Dog’s Last Will and Testament

October 30, 2009 by Lisa  
Filed under Blog

On the 1 year anniversary of our Reiley passing away, I thought I would post this poignant piece of writing.  May it help any of you that are going through what we went through just a year ago.  Our hearts still ache & we miss our girl everyday but know she is feeling better now. ~ Lisa

I came across this wonderful piece of writing by Eugene O’Neill, the well known American playwright and a Nobel prize recipient. He reportedly wrote this to comfort his wife when their beloved dog, Blemie, was in his last days:

” Last Will and Testament”

I, Silverdene Emblem O’Neill (familiarly known to my family, friends and acquaintances as Blemie), because the burden of my years is heavy upon me, and I realize the end of my life is near, do hereby bury my last will and testament in the mind of my Master. He will not know it is there until I am dead. Then, remembering me in his loneliness, he will suddenly know of this testament, and I ask him then to inscribe it as a memorial to me.

I have little in the way of material things to leave. Dogs are wiser than men. They do not set great store upon things. They do not waste their time hoarding property. They do not ruin their sleep worrying about objects they have, and to obtain the objects they have not. There is nothing of value I have to bequeath except my love and my faith. These I leave to those who have loved me, to my Master and Mistress, who I know will mourn me most, to Freeman who has been so good to me, to Cyn and Roy and Willie and Naomi and – but if I should list all those who have loved me it would force my Master to write a book. Perhaps it is in vain of me to boast when I am so near death, which returns all beasts and vanities to dust, but I have always been an extremely lovable dog.

I ask my Master and Mistress to remember me always, but not to grieve for me too long. In my life I have tried to be a comfort to them in time of sorrow, and a reason for added joy in their happiness. It is painful for me to think that even in death I should cause them pain. Let them remember that while no dog has ever had a happier life (and this I owe to their love and care for me), now that I have grown blind and deaf and lame, and even my sense of smell fails me so that a rabbit could be right under my nose and I might not know, my pride has sunk to a sick, bewildered humiliation. I feel life is taunting me with having over lingered my welcome. It is time I said good-by, before I become too sick a burden on myself and on those who love me.

It will be sorrow to leave them, but not a sorrow to die. Dogs do not fear death as men do. We accept it as part of life, not as something alien and terrible which destroys life. What may come after death, who knows? I would like to believe with those of my fellow Dalmatians who are devout Mohammedans, that there is a Paradise where one is always young and full-bladdered; here all the day one dillies and dallies with an amorous multitude of houris, beautifully spotted; where jack-rabbits that run fast but not too fast (like the houris) are as the sands of the desert; where each blissful hour is mealtime; where in long evenings there are a million fireplaces with logs forever burning and one curls oneself up and blinks into the flames and nods and dreams, remembering the old brave days on earth, and the love of one’s Master and Mistress.

I am afraid this is too much for even such a dog as I am to expect. But peace, at least, is certain. Peace and long rest for weary old heart and head and limbs, and eternal sleeps in the earth I have loved so well. Perhaps, after all, this is best.

One last request I earnestly make. I have heard my Mistress say, ‘When Blemie dies we must never have another dog. I love him so much I could never love another one.’ Now I would ask her, for love of me, to have another. It would be a poor tribute to my memory never to have a dog again. What I would like to feel is that, having once had me in the family, now she cannot live without a dog! I have never had a narrow jealous spirit. I have always held that most dogs are good (and one cat, the black one I have permitted to share the living-room rug during the evenings, whose affection I have tolerated in a kindly spirit, and in rare sentimental moods, even reciprocated a trifle). Some dogs, of course, are better than others. Dalmatians, naturally, as everyone knows, are best.

So I suggest a Dalmatian as my successor. He can hardly be as well bred, or as well mannered or as distinguished and handsome as I was in my prime. My Master and Mistress must not ask the impossible. But he will do his best, I am sure, and even his inevitable defects will help by comparison to keep my memory green. To him I bequeath my collar and leash and my overcoat and raincoat, made to order in 1929 at Hermes in Paris. He can never wear them with the distinction I did, walking around the Place Vendome, or later along Park Avenue, all eyes fixed on me in admiration; but again I am sure he will do his utmost not to appear a mere gauche provincial dog. Here on the ranch, he may prove himself quite worthy of comparison, in some respects. He will, I presume, come closer to jackrabbits than I have been able to in recent years. And, for all his faults, I hereby wish him the happiness I know will be his in my old home.

One last word of farewell, Dear Master and Mistress. Whenever you visit my grave, say to yourselves with regret but also with happiness in your hearts at the remembrance of my long happy life with you: ‘here lies one who loved us and whom we loved.’ No matter how deep my sleep I shall hear you, and not all the power of death can keep my spirit from wagging a grateful tail. “

Family and friends,

We want you to know that Karna, our 5 year old German Shepherd, was put to sleep today due to irreversible liver disease.

He was a brave and loving dog who brought warmth and affection to all he met. He will be deeply missed.

Love,

Tony and Melissa

Financial Assistance for Veterinary Bills

PLEASE CONTACT KARNA’S OWNER, TONY, DIRECTLY IF YOU HAVE ANY INFORMATION THAT MAY HELP HIM AND HIS FAMILY

tony.cerrito@gmail.com

Thank you for the wonderful web site you created dedicated to Canine Liver Disease. I’ve found the information helpful in understanding the disease diagnosis I just received for my 5-year old male German Shepherd, Karna (a rescue).

After treatment in August from my veterinarian for cracking and flaking paws and lethargy proved unsuccessful, she referred me to the North Carolina State University Veterinary School for a diagnosis at their dermatology clinic. I took him last week and was informed that Karna had Phenobarbital induced (he has a history of seizures) Hepatocutaneous Syndrome – also known as necrolytic migratory erythema (NME). This is apparently a new and extremely rare disorder. They want to start a treatment on him quickly that will cost $750-1500 initially, with one or two additional treatments possible and ongoing therapies of injections (administered by yours truly) 3-4 times a day.

Here’s the reason for my email: I am currently unemployed and have been for some time (my profession is tied to the construction industry – hardest hit in this economy, as you probably know). I received my last unemployment insurance check in June and my wife and I are hanging on by a thread. This event with Karna has already put us in debt to the tune of nearly $1200 on top of an additional $700 we spent in February at another specialist (canine neurologist) for treatment of anticonvulsant toxicity he was diagnosed with then. I’m not complaining, I’d do it all over again. We love our boy very much. But we’re facing the reality now of having to make a decision between treatment or euthanasia because we have come to the end of our financial resources. I have asked the NCSU Vet School if we would qualify for financial assistance. The person who makes that decision is out until this Monday when I am scheduled to take Karna in for treatment. So we do not yet know if we will qualify. But we are taking a leap of faith and going ahead with the treatment in the hopes that we will be approved for assistance. However, if we are NOT approved, we will be in financial trouble and likely will be at the tipping point of being able to pay our bills. So I want to ask you if you can direct me to any other organizations that might be able to help my wife and I pay for Karna’s treatments.

Karna is probably the sweetest dog I’ve ever owned. He loves absolutely everyone and doesn’t have a mean bone in his body. He is a frequent hugger, known to wrap his long neck around the legs of those he meets. He deserves a shot at regaining his health. He’s been a brave boy through all of his misery and we want so much to save him. He has many years left in this world if we can do so. The doctor who will be treating him (Dr. Olivery) is optimistic that the treatments will help Karna regain liver function, but admits that only time will tell. Unfortunately, because of the economic downturn, the timing for all of us in this matter couldn’t be worse. I am not one to ask for charity, but I see no other course right now if I wish to try and save my buddy. Any information or help you might be able to provide is very, very much appreciated.

Memorial Writing

February 26, 2009 by Lisa  
Filed under Blog

Someone posted this nice memorial to a Canine Liver Disease group that I belong to. I thought it was very well written and poignant

Written and © copyrighted by Terri Onorato

I know what you’re thinking. You think I’m dead. Because you cannot see me
with your human eyes, cannot feel me with your hands or hold me in your arms
you think I am gone forever. You recall how I looked when I left this earth
and you cannot remotely imagine that I am alive in another place. You are
racked and torn by the pain of our separation and it blinds you to that
which is right in front of you…me.

How many times since I left your immediate sight have you been told that I’m
dead and you should “get over it”? How many times have you cried yourself to
sleep because you feel like an outcast, believing you’re supposed to get
over me because that’s what people say is normal but somehow you can’t and
no one seems to understand? How many times have you put yourself through
such excruciating pain because you aren’t willing to consider that I am not,
by any means, dead?

I want you to do me a favour and go back in time with me. Remember the
glorious day you brought me home – was I not the most intriguing creature
you’d ever met? Did I not make you laugh and giggle? Did I not look at you
with such adoration that you wanted nothing more than to spend the rest of
your life with me? I wanted this too.

Remember the days when I was in my prime and we did many things together.
You were so proud of me! I was a good friend and I took care of you when you
cried, were angry or felt down and unhappy. When you didn’t have a lot of
time for me because of your obligations, I waited patiently for you. I was
always there when you needed me. Did I not look at you with such acceptance
and patience that perhaps at times you felt a bit unworthy? You were never
unworthy in my eyes.

Remember when age crept up on me, my bones became stiff and my movements
slower. Still I met you when you came home and followed you around. We’d
been together for so long, I was your very best friend regardless of what
you were doing, saying and thinking. Did I not look at you with such
kindness and understanding that you felt overwhelmed? I couldn’t get enough
of you.

Remember the last time we saw each other with earthly eyes. You tried to be
brave but I knew you were crying…I know you so well, better than anyone
else in the world. Did I not look at you with such pure trust and love that
you yearned only to hold me close and keep me with you always? Did you not
promise that you would love me forever? I believed you.

If this is so then why have you let me go by thinking I no longer exist?
Remember the depth of love in my eyes when I looked at you.
I am no longer an earthly figure, this is true. My
body was only part of who I really am and it would have been but a mere
shell on earth if it were not filled to overflowing with my soul, my spirit
and my loving light. When we met you thought I was cute, pretty and adorable
What kind of relationship would we have had if this were all that I’d been?
How could you have loved me if I’d had no spiritual substance?

We are all made up of energy that resides far deep down inside of us, it is
our core and our soul, spirit and loving light. It is the energy that is all
of life…it has no beginning, it has no end. It simply is and always will
be and without it there is no life. You can’t see it with the naked eye nor
can you hold it in your hand, it is simply a certain knowing that this
energy does exist. It’s a knowing just as you know that our love existed on
earth – you couldn’t see our love in a solid sense, you couldn’t gather it
all up and confine it to one place. But you *knew* it existed. There was no
doubt in your mind.

There are those who demand you get over me, insisting that I’m dead and you
ll never see me again because animals don’t go to Heaven. Oh really? I’m
here to tell you different. You were as worthy of my love and undying
devotion on earth as I was of yours. Do you really believe this love would
be snatched from us *forever* simply because I wasn’t
human? Was I not a living, breathing creation with personality? How could I
have been so if I didn’t possess the energy of soul, spirit and loving
light? And if this energy is and always will be, then how can it be that I
am dead? If my core is not the energy that is all of life then I was never
alive to begin with. But you know better.

You cry because you miss me, this I understand. I miss you too – I miss the
belly rubs, hugs and kisses that we shared. But life does go on beyond these
wonderful, fulfilling physical connections. I came to this place to continue
on in a new life, not because I didn’t love you anymore or because I wanted
something better. I came here because it was time for me to go to the next
phase of my existence, something all living creatures must do eventually. It
is the normal progression of life. I was not taken away from you because you
cannot take away that which was never owned. My presence in your life was
and is a gift to be cherished and honored just as I cherish and honor you.
Life is not simply about being born into a body, living a certain number of
years and then dying. Energy cannot die. We are blessed with time in a body
so that we can learn, share and grow. It prepares us for the next phase of
our eternal life. The body holds within it the true life force of our
existence…our soul, spirit and loving light. Without these our bodies
would be empty, blank, void of feeling and expression. Without our energy we
would indeed be dead and could never have experienced our love for each
other.

You say that all you have left are memories but this is not so. You see,
when I took leave of my earthly body I left a little something behind for
you. You can’t touch it, hold it or examine it, for what I left behind is
far too uninhibited for confinement. I left in your tender care a piece of
my soul. I placed it right next to your own which is quite fitting as we
were always side by side in our earthly life together. I love you too much
to have left you with nothing but memories that tend to fade and grow cloudy
as the years go by. I love you too much to have vanished without a trace.
How selfish it would be of me to remove love and light from your life.

I understand your tears, each one you shed is testament to your love for me
and I am honored and humbled. But don’t forget the good things we shared -
remember and smile. This is an honor for me as well. When you need me I will
be here. Close your eyes, relax, take slow, deep breaths and picture me in
your mind. Shut off the world and your notions of what you think death is
and give me a chance. Look for the subtle signs I send you. Don’t stop being
proud of me, I am a friend to be proud of, I am still your friend and soul
mate. Don’t memorialize the death of my body but instead honor and celebrate
my never-ending life for it is eternal and forever as is my love for you.
Until we meet again…

Canine Liver and Anatomy

January 7, 2009 by Lisa  
Filed under All Info, Anatomy/Function (Liver)

Comments Off

Canine liver disease is among the top five leading causes of non-accidental death in dogs and as such should be taken seriously. The liver is responsible for a number of essential bodily functions, and if it is compromised in any way your dog’s overall health is in jeopardy.

FUNCTION

Among the liver’s many responsibilities are blood detoxification, waste removal and bile production to aid digestion. This large gland is involved in just about every process in the body. As such, it is very resilient, with the ability to work even during the onset of liver disease in dogs.

It is involved with almost all of the biochemical pathways that allow growth, fight disease, supply nutrients, provide energy, and aid reproduction. Liver cells, which are called hepatocytes, go through thousands of chemical reactions every second in order to perform these myriad functions. Since the liver is involved with almost all biochemical processes it is no wonder that there are many different diseases that will affect it.

The liver processes raw materials, manufactures the building blocks of the body, recycles the old to make new, and detoxifies the industrial waste of the body. In short the liver is involved in just about every biochemical process required to run the body. As a result of this relationship, liver disease can affect just about any other part of the body and thus the symptoms of liver disease are typically unpredictable and non- specific. Furthermore, because the liver acts as a “biochemical cross roads” for the body, it is affected by a wide range of diseases, including viral and bacterial infections, degenerative and neoplastic disease, and toxic insults. It is estimated that three per cent of all disease seen by veterinarians is liver based.

The liver has a double edged nature which, while being life preserving, makes diagnoses and treatment of liver disease extremely difficult. The liver has a tremendous reserve capacity, which means that it can easily perform its duties with up to 70 to 80 per cent of the liver mass affected by disease. While it certainly is a benefit that our liver can keep us alive despite an overwhelming infection or a massive tumor, it also means that the disease is well advanced and possibly untreatable before any symptoms are noted. We all know that disease is most easily conquered early, but the very nature of the liver makes this an impossible task. One thing about livers though: they are the only organ in the body which is capable of complete regeneration and thus is we do manage to successfully treat the disease, there is a chance of complete recovery.

SPECIFIC LIVER FUNCTIONS


Metabolism

The liver is the organ that orchestrates the metabolism of fats, carbohydrates, and protein. It does this in conjunction with the circulatory system, the lymphatic system, and the endocrine (hormone) system. A healthy liver is critical to proper protein, carbohydrate, and fat metabolism.

*Protein Metabolism

The liver produces all of the proteins except for the proteins synthesized by the immune system. It does this by reassembling amino acids into protein. The main protein produced by the liver is called albumin.

Normal albumin in the bloodstream is important for many physiologic functions. One of these functions involves the normal maintenance of fluid pressure in the arteries and veins. When the protein level falls below a certain point the fluid in these vessels can leak out and pool in the abdominal or thoracic cavities. This fluid is called ascites when it occurs in the abdominal cavity, pleural effusion when it occurs in the thoracic cavity. Albumin also functions to “carry” other compounds through the bloodstream. These compounds include calcium, vitamins, hormones, fatty acids, many drugs, and bilirubin.

A consistent finding with liver disease is a low protein level (hypoproteinemia). This low level usually occurs only when the liver has been severely diseased for a prolonged period of time, because of the great reserve capacity of the liver to produce more albumin.

*Carbohydrate Metabolism

With the aid of the hormones insulin and glucagon, the liver maintains a normal blood glucose level. Abnormalities in blood glucose level can result from an insulinoma or diabetes mellitus (sugar diabetes).

Glucose that is stored in hepatocytes is called glycogen. It is used as a reservoir during times when carbohydrate intake is low (fasting or starvation). The liver can also manufacture glucose from proteins or fats.

In liver disease the body can have a difficult time regulating the blood glucose level, usually leading to hypoglycemia (low blood glucose). This is one of the reasons why caloric intake is an important aspect of treatment.

*Lipid Metabolism

The liver regulates fats (called fatty acids) in the bloodstream. It does this by converting excess amounts of carbohydrates and proteins into fatty acids. The liver also manufactures cholesterol from this fat. Cholesterol is necessary for many functions, particularly the sex hormones and steroids like cortisone.

Detoxification

Drug detoxification is an important liver function. It is a complex process that occurs in the endoplasmic reticulum of the hepatocyte. Several phases are involved with this detoxification:

*Phase I

The offending drug is inactivated. This inactive drug is eliminated by the body, usually through the kidneys, or secreted into bile and passed out in the feces.

The drug is converted from an inactive drug to an active metabolite. This active metabolite circulates in the bloodstream and has an effect on the body.

The drug is converted from an active drug to an active metabolite.

*Phase II

In this phase biochemical processes occur that make these drugs more water soluble and thus easier to eliminate through the kidneys. They are excreted out of the body in the urine.

Another example of this detoxification process occurs with the compound ammonia. Ammonia is one of the by-products of the digestion and metabolism of protein into amino acids. Ammonia is detoxified by the liver and excreted by the kidneys. A diseased liver will not metabolize this ammonia to urea properly, leading to the disease called hepatic encephalopathy.

Bile Metabolism

Bile is made up of electrolytes, cholesterol, bile acids, bilirubin, and globulins. It is produced by hepatocytes, secreted into channels in the liver called and stored in the gall bladder. Drugs are eliminated in the bile, red blood cells are re-circulated through the bile system, and fats are absorbed from the intestines into the bloodstream only in the presence of bile.

When red blood cells break down and are recycled they release bilirubin from their hemoglobin. The liver, along with spleen and bone marrow, recycle this bilirubin, salvaging some of the compounds and excreting the rest in the bile. Bilirubin, which is toxic, binds to albumin and is detoxified and excreted. This is eventually excreted into the intestines and broken down by intestinal bacteria, where it imparts the dark color to stool. If this bilirubin cannot be excreted from the gallbladder (when there is an obstruction in the bile duct) there will be very light colored stool. The excess amounts of bilirubin that build up in the bloodstream will cause jaundice, the yellow discoloration of the skin and mucous membranes that can occur with liver disease.

The fat soluble vitamins, A, D, E, and K, require bile for proper absorption from the intestines. These vitamins are stored in the liver, and are converted to active compounds as the liver maintains normal physiology.

Coagulation Factors

The proteins that initiate and maintain clotting of blood are synthesized by the liver. These proteins go through very complex biochemical processes to achieve this vital function. A diseased liver is unable to synthesize these proteins, leading to a potential bleeding problem. Vitamin K is also an essential component of these clotting mechanisms.

Red Blood Cell System

The liver removes old or damaged red blood cells from the circulation, and is involved with the storage of iron and the breakdown of hemoglobin. Because of this, chronic liver disease could cause anemia. The liver (along with the spleen), is a storage organ for blood. If there is a severe blood loss the liver expels this blood into the bloodstream to help make up for the loss.

Reticuloendothelial System

Specific cells called Kupffer cells line the inside of the liver. These cells are part of the immune system. They eliminate and degrade the substances that are brought into the liver by the portal vein. Some of these substances are bacteria, toxins, nutrients, and chemicals. A diseased liver will not filter these compounds normally, resulting in toxic accumulations of drugs, chemicals, or bacteria. Excess accumulation of bacteria in the bloodstream is called septicemia, and is one of the reasons that antibiotics are commonly used in liver disease.

Vitamins

Many vitamins are stored in the liver, and perform their functions only when activated by the liver, and are degraded by the liver. These include some of the B vitamins and Vitamin C, along with A, D, E, and K previously described.

ANATOMY

The pictures in this section are reprinted with permission by the copyright owner, Hill’s Pet Nutrition, from the Atlas of Veterinary Clinical Anatomy. These illustrations should not be downloaded, printed or copied except for personal, non-commercial use

The liver is a multi-lobed organ that is located at the most forward part of the abdomen. It is so far forward that it lays up against the diaphragm, the muscle that aids in breathing in mammals. The liver is the largest organ that is located in the body, a testament to its importance. It has 6 distinct lobes organized into 3 regions. Like the kidneys, 25% of the blood ejected with each beat of the heart goes to the liver.

The liver is supplied with nutrients from the hepatic artery and the portal vein, which is different from other internal organs. Blood from the heart goes through the aorta and into the hepatic artery. The hepatic artery supplies a large amount of the oxygen and nutrients the hepatocytes use during metabolism. Approximately 1/3 of the blood that flows into the liver comes from this artery.

The other source of blood for the liver is the portal vein, supplying 2/3 of the blood that flows into the liver. The nutrients in the portal vein originate from the digestive tract, this time, not the heart, like the hepatic artery does. In essence, raw food that is absorbed from the intestines flows directly to the liver. This exposes the liver to toxins and bacteria, which are metabolized and detoxified by a normal liver before they leave the liver and enter the general circulation via the heart. This detoxification process protects other organs, particularly the brain, from bacteria and toxins that could injure brain cells. When this system fails, which happens in liver shunts, excess ammonia will build up in the bloodstream and affect the brain.

Signs and Symptoms of Canine Liver Disease

January 6, 2009 by Lisa  
Filed under All Info, Symptoms

Comments Off

We cannot stress enough that the symptoms of liver disease are VERY subtle and your dog may be acting normal other than a few small differences in behavior.  DO NOT WAIT TO CONSULT YOUR VETERINARIAN.  Often times, by the time the symptoms below are present, the disease is quite advanced.  Early detection is the KEY for treatment and survival.

Pets with liver disorders can show a variety of physical symptoms. Very few of the symptoms are specific for liver disease, but can be signs of multiple diseases and conditions. Symptoms of liver disease are variable and subtle in the early stages of the problem.  All, some, or only one of these signs may be present:

Loss of appetite – Anorexia (Most Common) – THIS IS VERY IMPORTANT AND ANY EATING CHANGES SHOULD BE REPORTED TO YOUR VETERINARIAN!!!

Intermittent recurrent abdominal or gastrointestinal upsets; vomiting, diarrhea, constipation

Progressive depression or lethargy; does not want to play anymore or refuses to go for walks.

Swollen belly with a “fluid filled” look. This is also known as ascites and is actually fluid accumulation in the belly due to circulation alterations in the abdomen.

Pale gray feces. Bile pigments are what give feces it’s characteristic brown color and if the liver is not processing bile properly, the feces will not get their color.

Orange urine. The improper processing of bile results in the excretion of bilirubin in the urine in high amounts, thus orange urine.

Jaundice, also known as icterus. Any pale or white skin or visible tissue takes on a yellow hue. Again the biliary pigments are accumulating in the body because the liver is not processing them.

Bleeding problems. Many of the proteins required for proper blood clotting are created in the liver. Remove these proteins and blood clotting decreases.

Hepatic encephalopathy, or severe neurological signs; behavioral changes, seizures, aimless pacing or circling, head pressing.

Pain associated with the abdomen. This is due to the stretching of the liver capsule. May be noted when the dog is lifted around the belly or when the veterinarian probes the abdomen. The veterinarian may also notice a swollen liver while palpating with some of the more acute liver diseases

Chronic weight loss or wasting. The liver processes all the building blocks. If it fails to process, the body fails to maintain itself.

Increased water consumption and urination. Most likely due to dramatic shifts in serum and kidney salt balances.

In a recent study it was found that dogs with liver disease can also have high blood pressure. This is called hypertension, and should be monitored to see if therapy is needed

If you notice any of the above symptoms, make sure you consult your veterinarian as soon as possible. Because the liver is able to function effectively even at 70-80% capacity, the disease may be in its advanced stages by the time the condition manifests itself.

Testing and Diagnosis of Canine Liver Disease

January 4, 2009 by Lisa  
Filed under All Info, Testing and Diagnosis

Comments Off

A thorough approach is needed for a correct diagnosis of any liver problem. An organ like the liver that
is so intimately involved with other important organs will exhibit symptoms that mimic disease in these other organs. Also, what initially might appear as a diseased liver is in reality a disease elsewhere in the
body that is involved with the liver secondarily. This is why it is crucial to follow a thorough and methodical approach called the diagnostic process.

Examination

Specifically noting signs which may indicate liver disease. Periodic ascites, intolerance of a high protein diet, icterus, chronic weight loss, abnormally colored feces or urine, bleeding disorders, chronic illness, and all that has been mentioned above. Sometimes urinary crystals formed from the improperly metabolized proteins and amino acids may indicate liver disease.

Liver disease can occur in pets of any age. If it occurs in young animals we tend to think more of toxicity, a liver shunt or a viral disease like adenovirus in dogs. In older pets we tend to think more of inflammation and cancer as the cause of the liver problem.

Several canine breeds are prone to getting liver disease:

Bedlington terriers, Skye terriers, Doberman pinschers, and West Highland White terriers get a
problem with excessive copper accumulation that results from failure of normal biliary excretion of copper. Cocker spaniels have an increased incidence of chronic hepatitis

History

Early signs of liver disease are subtle, and might exhibit as some of the symptoms described above. It is important to remember that some pets do not show any symptoms early in the course of the disease. This is another reason for yearly exams, along with blood and urine samples in dogs and cats 8 years of age or more. Even though many cancers do not show up in a blood sample, we can sometimes get indirect evidence there is a problem, leading to additional diagnostic tests that might find cancer.

The recent use of pesticides, insecticides, and drugs might give us a clue. Some Labradors are sensitive to the use of the arthritis medicine Rimadyl. These dogs should have a blood panel analyzed prior to initiating Rimadyl therapy. Every 6 months this panel should be repeated.

A history of poorly controlled diabetes mellitus might also clue us in to liver problems. Pets with
liver shunts might have stunted growth and become depressed right after eating.

Physical Exam

Routine physical exam findings might include:

Distended abdomen due to enlargement of the liver (hepatomegaly) might be found. This can be palpated in some situations, especially in the smaller animals. an enlarged liver from a disease other than liver disease can cause hepatomegaly. This includes heart disease and Cushing’s Disease.

Enlarged lymph nodes due to secondary bacterial infections or spread of a primary or metastatic
liver tumor.

Bruising (hematoma) might be observed under the skin, or when a blood sample is obtained. This is
due to the liver’s affects on the clotting mechanism

Fever- a rectal temperature of greater than 103 degrees F could accompany liver disease when inflammation or infection is present

Skin infections and wounds that do not heal, or recur after antibiotics are stopped

Yellowish discoloration (icterus or jaundice) of the ears, gums, or hairless areas of the skin

Anemia might be observed by checking the mucous membranes for a normal pink color

Extensive Blood Work and Diagnostic Testing

A complete blood count to check for anemia and blood cell abnormalities. A CBC (complete blood
count) and BCP (biochemistry panel) should be run on every pet 8 years of age or more, especially if they have any of the symptoms of liver disease. The CBC might show a decrease in the number of red blood cells (RBC’s). This decrease in RBC’s is called anemia. The white blood cell count (WBC) might be elevated (leukocytosis), normal, or decreased (leukopenia), mostly depending on the cause of the liver problem and how long it has been present. A change in the WBC’s does not necessarily indicate there is a liver problem.

A complete chemistry screen, including ALT, ALP, AST, bilirubin, glucose, urea, electrolyte levels,
albumin, globulin and bile acid levels. The bile acid levels should be checked on an empty stomach and two hours after feeding. All these values, with the exception of the bile acids, usually are included on
a standard Small Animal Data Base Screen.

Important Liver Enzymes

Traditionally the medical practitioner has measured the relative concentration of several enzymes which may indicate alterations in liver health. The following enzymes typically change values in the face of liver failure

Alanine Aminotransferase: ALT – Liver specific. Cell damage will cause elevations of ALT due to leakage. The elevation of the enzyme correlates with the number of cells damaged. Falling levels of ALT may indicate recovery or may indicate a failing number of functional liver cells. Rapid increases in ALT may indicate an acute process, while slow increases may indicate bile duct obstruction.

Normal Test Range: 10-100 U/L*

Aspartate Aminotransferase: AST - an enzyme seen in the liver, heart, kidney, skeletal muscle and brain. The half life of the AST in the blood stream is much shorter than that of ALT, therefore the values of AST tend to drop more rapidly once liver function is resumed. AST elevations and ALT elevations should parallel each other in liver disease

Normal Test Range: 5-55 U/L*

Alkaline Phosphatase: ALKP/ALP – This enzyme is present in many tissues, therefore it not very specific in liver disease, but it appears very early in the progress of liver disease, therefore it is considered quite sensitive. ALP tends to be slightly more specific in the cat, but not quite as sensitive. A similar enzyme or isoenzyme is secreted as a result of high levels of cortisone, therefore an effort must be made to separate Cortisole induced ALP or CALP and normal ALP. Liver ALP is released from the liver when many anticonvulsant drugs are administered to the dog. This must be taken into account when evaluating ALP levels. ALP levels typically are greatly elevated in the young, growing animal and therefore a veterinarian should not mistake any elevations as disease in a young animal.

Normal Test Range: 23-212 U/L*

Gamma Glutamyltransferase: GGT – This enzyme is has its highest concentration in the kidneys and pancreas, but it is also found in the liver and other organs. The major proportion of GGT in the serum seems to come from the liver. Elevations of GGT in disease seem to stem from new synthesis rather than leakage, therefore the changes seen due to disease are not spectacular. Large elevations of GGT are more commonly associated with pancreatitis and bile duct obstruction.

Bile Acids

These series of organic acids circulate almost entirely in the localized blood flow between the intestines
and the liver (a.k.a. the Portal system). The flow is typically from the liver, into the bile duct system, then excretion into the intestines to aid digestion after a meal, to be re- absorbed into the portal system and recycled by the liver. Very little of the bile acids escape from the portal circulation system into the rest of the body. Leakage is considered abnormal and is a sure sign of a liver abnormality. This is one of the most sensitive tests available to diagnose liver disease. While the liver does actually manufacture this product, it has tremendous reserve capacity and can easily meet the bodies demand for bile acids despite severe disease. As a result of this reserve, the bile acid levels do not typically drop due to liver disease.

Normal Test Range: Pre = Less than 7.0 umol/L, Post = Less than 15.0umol/L*

A complete urine analysis

Check urobilinogen levels, bilirubin levels, glucose levels, protein levels. Again all this is usually on a standard urinalysis panel.

Radiograph the abdomen

X rays can show increased liver size, decreased liver size liver abscesses, abnormal mineralization , and circulatory abnormalities (using special dyes).

Ultrasound the liver

Perfect technique for visualizing the circulation of the liver, the bile duct system, the density of the liver tissue, the size of the liver. Ultrasound is highly beneficial in the diagnosis of liver disease. We recommend ultrasounding a liver when the liver enzymes tests are elevated over time, or the bile acids test is abnormal. The internal structure (called parenchyma) can be analyzed, and post-hepatic liver disease can be differentiated from hepatic liver disease. This can be very important because disease in the liver can often be diagnosed with a biopsy during the ultrasound. Post-hepatic liver disease cannot easily be diagnosed in this matter. Instead it is diagnosed and treated with an exploratory surgery (called a laparotomy).

Biopsy of the liver

While this is a surgical technique, it is the ultimate for diagnosis, since it allows us to directly examine and test liver tissue, give an absolute diagnosis and hopefully a final treatment regime. Biopsies can be taken by full laparotomy, where the surgeon actually looks at the liver and removes a small piece, or they can be done by a biopsy needle guided by ultrasound through the body wall. The liver will regenerate any piece that has been removed, therefore liver biopsy is usually a low risk procedure in capable hands.

*The ranges for the test results listed above are dependent on the lab, the testing done and are relative. Some specialist allow for a much larger range before they diagnose “true” Liver Disease. After receiving your test results, please consult with an internal specialist and have them explain the results to you.

Treatment Options for Canine Liver Disease

The course of treatment required in a case of canine liver disease will depend upon the cause of the condition. For example, if trauma was the trigger, hospitalization while the dog recovers from the impact of the trauma may be all that is required. On the other hand, antibiotics may be needed if a bacterial infection is at the root of the disease. Furthermore, when liver disease is caused by another medical condition such as cancer or anemia, these additional medical circumstances will need to be taken into account.

In addition to certain medications, dietary adjustments and supplements can be very useful when attempting to treat canine liver disease. Dietary changes can include adjusting the amounts of proteins, vitamins, carbohydrates, fats, and minerals that a dog ingests. This will then ensure that the canine patient is receiving the nutrition it needs and will also help to decrease the stress and workload of the liver.  Furthermore, vitamin K can be helpful with respect to controlling bleeding disorders while vitamin E, as an antioxidant, helps to remove free radicals and to prevent continued oxidative damaged to the canine’s liver.

Certain homeopathic remedies can also be very helpful when treating canine liver disease. Natural herbs and substances such as burdock and greater celandine have properties that assist with the purification of blood, the stimulation of digestive enzymes, and the protection of the liver from toxic substances. Also, some such substances have anti-inflammatory and antibacterial properties.

Milk thistle is another natural ingredient that is known to be very effective in cases of canine liver disease. This natural substance acts as an antioxidant like vitamin E, stimulates production of new liver
cells, and helps to prevent certain toxins from attaching to the liver.

Thus, many natural substances and remedies can be very beneficial for dogs suffering from liver disease. However, it is always important to carry out any form of treatment under the supervision of a qualified veterinary doctor.

SPECIFIC TREATMENTS AND PROGNOSES

Portal Vascular Abnormalities

Fluids and Electrolytes – This corrects the dehydration that occurs with a poor appetite and supplies needed sodium, potassium, and chloride. This fluid is usually given intravenously (IV) at first. Pets
that are severely ill from PSS should not be given anything orally initially.

Cleansing Enemas – Enema’s will decrease the bacterial count of the intestines, leading to less ammonia absorption.

Lactulose – Lactulose works in the large intestine to minimize the production of ammonia by bacteria. It does this by changing the pH and converting ammonia to a form that is not readily absorbed into the bloodstream. It also stimulates normal colon bacteria to absorb ammonia, which is then passed in the feces. Finally, it stimulates the intestines so that ammonia passes through faster, which means there is less time for absorption.

Antibiotics – These drugs are also administered, especially if mental depression is present. They minimize the bacteria count in the colon, thus reducing the amount of ammonia that is absorbed
from the intestines into the bloodstream. They work well with lactulose to decrease the ammonia level.

Dietary Modification – A diet that is restricted in protein may be beneficial because less ammonia is produced as a by-product of metabolism. This protein needs to be of high biological value, such as eggs and dairy products. Meat based proteins should be avoided since they can increase the chance of HE. Most of the caloric needs of a pet with PSS should be supplied with carbohydrates like rice and pasta. Higher fiber diets might also be helpful, as long as the dog or cat is not undernourished. They can act to minimize ammonia production and absorption in a manner that is similar to lactulose

Surgical – For many PSS cases surgery is the treatment of choice. The abnormal vessel that is shunting blood around the liver is identified and closed (ligated) to minimize blood flowing through it. When the abnormal blood vessel is ligated blood will now flow through the liver instead of around it. This is readily accomplished for solitary extrahepatic shunts. Intrahepatic shunts can be more difficult
to identify and ligate. Post surgical monitoring is important. If the pressure within the liver becomes too high due to the increased blood flow through the liver then the ligation on the shunting vessel(s) must be reduced or removed.

In some cases medical management must also be utilized to affect a cure. The final outcome of treatment depends on what age the PSS started, how long it has been present, and whether it is intrahepatic (worse prognosis) or extrahepatic in nature.

Long Term Monitoring – Pets on long term medical care need to be monitored carefully. Body weight, albumin, and total protein are watched to ensure adequate protein in the diet. Initially, these tests should be performed monthly, then every 3 months. In addition to the above tests, bile acids are monitored monthly, then every three months to assess the vitality of the liver. Blood ammonia levels are monitored monthly to assess effectiveness of treatment. When stable, ammonia levels can be monitored every 3 months.

Prognosis – Many pets with isolated extrahepatic shunts return to a normal life after surgery. There is no guarantee that surgery will correct the problem, especially those pets that develop the disease very early in life. Some of them will need medical management simultaneously. The prognosis for pets that are treated only medically varies.

Chronic Active Hepatitis

Fluids and Electrolytes – This corrects the dehydration that occurs with a poor appetite and supplies needed sodium, potassium, and chloride. This fluid is usually given intravenously (IV) at first. It can be given subcutaneously (SQ) at home after the initial dehydration is corrected. B-Complex vitamins are routinely added to the fluid bag. Care must be taken not to give excessive amounts of fluids, especially if they contain sodium, in pets with fluid buildup in the abdomen (ascites).

Treating the Cause (when known) – Antibiotics are used to control bacterial infections and drugs that are suspected of causing this disease are stopped. We tend to use antibiotics that have minimal need for liver metabolism in order to minimize their toxic effects.

Rest – The liver has ability to heal itself if the disease is not too advanced. Rest can be a big aid, along with proper nutrition.

Ascites Reduction – Sodium restriction helps minimize fluid buildup (ascites) in the abdomen. This can be accomplished using Hills K/D Prescription Diet. Diuretics like Lasix are also used to help pull this fluid out of the abdomen.

Dietary Modification – Using a diet that is restricted in protein may be beneficial because less ammonia is produced as a by-product of metabolism. This protein needs to be of high biological value, such as eggs and dairy products. Meat based proteins should be avoided since they can increase the chance of HE. Higher fiber diets might also be helpful, as long as the dog or cat is not undernourished. This is the same basic diets as for pets with PSS (see above).

A diseased liver needs calories, which sometimes need to be supplied with a feeding tube.

Ulcer Treatment – This will make pets more comfortable, more inclined to eat, and prevent bleeding in the stomach.

Liver Specific Drugs:

Corticosteroids – Cortisone is used if there is evidence that the immune system is implicated as a cause
of the liver problem.

Ursodiol – This drug replaces toxic bile acids with a type of bile that is less toxic.

Zinc Supplementation – Might help reduce the effects of copper toxicity.

Long Term Monitoring – CCHID monitoring is similar to PSS (see above). In addition, repeating a liver biopsy 6 months after initiating therapy used.

Infectious Canine Hepatitis

Like most viral diseases therapy is directed towards symptoms. When symptoms are severe enough, intravenous fluids are administered. Since clotting factors can be disrupted particular attention needs to be paid to bleeding problems. If bleeding problems are severe enough, a whole blood transfusion must be administered. Dogs that are comatose may need intravenous glucose.

Copper Toxicosis (Copper Storage Disease)

Treatment has two goals – Enhance excretion of excess copper, and minimize further absorption of copper from the intestines.

Chelating agents – Drugs like penicillamine bind with copper to allow easier excretion.

Zinc – Zinc will help minimize further copper absorption from the intestines.

Supportive Care – Similar to other liver diseases previously described.

Long Term Monitoring – Serum, enzymes, and bilirubin should be monitored at least every 6 months.

Cancer

Primary hepatic neoplasms are treated by removal of the affected liver lobe when possible. If multiple lobes are involved then surgery is usually not performed. Secondary hepatic neoplasms are treated with chemotherapy. The results vary, and depend on the duration, location, and degree of malignancy of the neoplasia.

The prognosis is poor for long term survival.

Supportive care that is similar to other liver diseases is also used in neoplasia.

Preventative Maintenance

Comments Off

1. LISTEN TO YOUR INSTINCTS. You know your dog better than any vet or specialist. If there is something “not quite right”, encourage blood tests to see what is going on. The symptoms of canine liver disease are so subtle and can be mistaken for so many other things, ask for a liver panel test to rule it out.

2. Educate yourself about the signs/symptoms of canine liver disease so that you are able to recognize them if any are present in your dog.

3. Feed your dog a high-quality balanced diet with easily digestible protein (beef and fish are harder for dogs to digest), no animal by-products, fillers or allergens.

4. Know your dog’s normal body temperature and take it regularly and if/when they show behavior changes. Temperatures above 103F may be linked to internal infection and may be affecting the liver.

5. Know your dog’s eating and bathroom habits. If there are even slight changes that extend over a period of a week or so, seek out the advice of your veterinarian.

6. Do not allow dogs to roam freely where they can encounter animals or insects, standing water or poisonous plants.

7. Routinely vaccinate dogs for infectious canine hepatitis and leptospirosis.

8. Take your dog in for a yearly exam that should include blood, stool and urine samples in dogs 8 years of age or more. (Veterinarians will do these tests on dogs under the age of 8 as well.)

9. If tests are abnormal or presenting high range numbers, seek out the advice of an Small Animal Internal Medicine Specialist – your vet should be able to refer you to someone in your area.

10. Practice good dental hygiene for your dog. Brushing your dog’s teeth helps rid the gums and mouth of harmful bacteria that, if left unchecked, can spread to the heart, liver and other vital organs.

11. Avoid medications such as Cortisone, Rimadyl and Phenobarbital if at all possible. Also try to minimize exposure to flea and tick products, heartworm medication, anti-fungals, etc.

* If Rimadyl cannot be avoided:

A blood panel should be taken and analyzed prior to initiating Rimadyl therapy.
Every 6 months this panel should be repeated.

* If Phenobarbital cannot be avoided:

Have a chemistry panel with the liver enzymes ALT, GGT and alkaline phosphate
done every 3 to 4 months.

If all three liver enzymes are severely elevated (more than just a few points
above normal) then you should do a urine bile acid test or a pre- and post-meal
bile acid test to see what kind of damage has been actually done to the liver so you
can change the diet to the liver cleansing diet and/or reduce the Phenobarbital.

Monitor Phenobarbital levels every 6 months, more frequently if you do not have
seizure control or if there are any signs of toxicity like ataxia, wobbliness, and hind end
weakness (not after a seizure).
