You’ve come to the right place if you’re looking for thorough, in-depth info about putting down a dog with liver shunt. But how do you know if your dog has liver shunt? I’m so glad you asked. Here I will explain what it is and how to treat it.
Despite your best efforts and the vet’s, you were ultimately unable to put down the dog with liver shunt.
Dogs are resilient, even if they have liver shunt and live their lives like they’re invincible to the laws of biology. Liver shunts are very scary because you don’t know what’s going to happen. We had Max on medication, but it didn’t help a whole lot. Again, we had no choice but put down our dog who was suffering. The right thing had to be done, even though it hurt us both, and the helplessness we felt.

The liver shunt is a condition where blood from the intestine bypasses the liver, which causes toxins to build up in the dog’s body.
This can be fatal if not treated, so it’s important to know how to put down a dog with liver shunt.
The first step is to take your dog to the vet. They will do an ultrasound to confirm that your dog does have a liver shunt, and they’ll also be able to determine whether or not it’s possible for treatment to work. If it’s not possible for treatment to work, then putting down your dog may be your only option.
If you need to put down a dog with liver shunt, there are a few options for doing so.
If your dog is in the early stages of liver shunting, and the bleeding has not yet been too severe, you may be able to treat them with anti-coagulants. Antithrombin III (ATIII) is an enzyme that helps prevent blood clots from forming. If your dog’s ATIII levels are low, they may be able to get treatment by taking injections or pills. This can help slow down or even stop the bleeding that occurs as a result of liver shunting.
If your dog’s liver shunting has progressed further, however, you may need to consider euthanasia as an option. You can discuss this option with your vet if it seems like it might be necessary for your pet’s health or well-being.
Putting Down A Dog With Liver Shunt
What is Liver Shunt?
“Portosystemic shunting” (PSS) or liver shunt is a condition in which the blood-flow to and from the dog’s liver has been compromised.
Specifically, liver shunt causes blood to flow around the liver, not through it, resulting in blood bypassing the liver.
There are two types of liver shunt in dogs:
- Congenital: a birth defect
- Acquired: the result of severe liver disease such as cirrhosis
Congenital shunts are more common in dogs than acquired shunts.
Development of Congenital Liver Shunt in Dogs
Congenital liver shunt in dogs can be “intrahepatic shunt” (“inside the liver”) or “extrahepatic shunt” (“outside the liver”). Both of these conditions are formed while the puppy’s body is developing inside the mother.
When a dog fetus is developing inside the mother’s uterus, it requires the help of the mother’s liver for liver functions, such as detoxification, protein production, and storage of glucose. Dog fetuses do not have a functional liver until the end of gestation.
Toward the beginning of gestation, there is a “naturally-occurring” liver shunt (a blood vessel called “ductus venosus”) that delivers blood through the dog’s liver directly to the heart.
In normal circumstances, the large liver shunt (ductus venosus) closes down shortly before birth so that the puppy can be born with a fully functional liver that works on its own. When the shunt does not seal closed when the puppy is born, the puppy is said to have an “intrahepatic shunt”.
An “extrahepatic shunt” occurs when there is a genetic abnormaly in which the blood flowing to the liver is re-routed around the liver instead of the blood going through the liver. This also occurs in-vitro when the puppy fetus is developing inside the mother.
Who are At Risk?
If a puppy has a congenital liver shunt, most commonly he will some signs by six months of age. However, shunts have been diagnosed in adults as old as 10 years. Female dogs are more susceptible to shunts than males.
Breed-wise, small breed dogs tend to have extrahepatic shunts. For example: Yorkshire terriers, schnauzers, maltese, dachshunds, Jack Russell terriers, shih tzus, poodles, to name a few.
Large breed dogs tend to have intrahepatic shunts and breeds that are predisposed include Irish wolfhounds, Labrador retrievers, Australian shepherds, Australian cattle dogs, and old English sheepdogs.
Signs and Symptoms of Liver Shunt in Dogs
If a dog is suffering from a liver shunt, he lacks the necessary materials (particularly protein) to give him a ready source of energy and to help him grow. This causes the dog to be smaller and weaker than normal.
Also, the liver is unable to properly get rid of all the toxins, causing toxin buildup in the bloodstream or kidneys. Toxin buildup often causes seizures in dogs.
In addition, a dog with a liver shunt may also show the following symptoms:
- Lack of appetite, resulting in weight loss
- Lethargy and general weakness
- Behavioral abnormalities (e.g. circling, stumbling, disorientation, unresponsiveness, staring into space, head pressing against objects)
There are other less common signs, such as:
- Excessive drinking and frequent urinating
- Diarrhea
- Vomiting
- Blindness

Diagnosis and Conventional Treatment
Initial diagnosis is through blood work. Blood urea nitrogen (BUN) and albumin concentrations in dogs with congenital liver shunts are usually low. Liver enzymes such as ALT and AST can be elevated.
Another key indication of liver shunts is extremely high blood bile acid concentrations (Normal bile acid concentration is about 20 whereas a dog with a liver shunt can have a concentration of over 100).
However, these are not enough for a definitive diagnosis. The only definitive way to tell if your dog has a liver shunt and the only way to tell if it is an “intrahepatic” or “extrahepatic shunt” would be by some extra diagnostics, such as CT scan, MRI, ultrasound, or exploratory surgery.
Extrahepatic shunts can be corrected by surgery relatively easily. Intrahepatic shunts, on the other hand, have a poorer prognosis and are more difficult to be surgically fixed. Dogs with intrahepatic shunts tend to have post-surgical secondary complications.
Diet for Dogs with Liver Shunts
Giving a proper diet to your dog with liver shunt is extremely important.
Since the liver is responsible for removing toxic byproducts arising from protein metabolism, a liver that is not functioning properly will cause wastes and ammonia to accumulate in the dog’s body.
For this reason, many vets suggest giving a protein-restricted diet to dogs with liver shunts.
However, according to Dr. Olson (author of Raw and Natural Nutrition for Dogs), proteins themselves are not the culprit. It is the ammonia that proteins produce that is the problem.
What it means for dogs with liver shunts is, they should be given high-quality, highly-digestible animal protein sources that produce the least amount of ammonia.
Examples of such protein sources include:
- Fish
- Chicken
- Eggs
- Dairy products (yogurt, cottage cheese)
Red meats such as beef produce the most amount of ammonia and should NOT be given to dogs with liver disease such as liver shunts.
A diet for dogs with liver shunts should preferably be home cooked and should contain:
- High-quality animal protein sources – Remember to use those that produce the least amount of ammonia.
- Complex carbohydrates (e.g. oatmeal, barley, pumpkin puree) – The soluber fiber in these foods can help absorb some of the ammonia produced.
- Healthy fat (e.g. Omega-3 fatty acids) – As fat is processed by the liver, feed only easily digestible fat (such as salmon oil) and in reduced amount.
As it is important to get all the nutrients right and balanced, be sure to work with a canine nutritionist or a vet who has training in nutrition to design a balanced diet for your dog.
Natural Remedies That May Help
If your dog has been diagnosed with a liver shunt, but is otherwise acting fine, you may want to use natural remedies to help manage your dog’s liver shunt problem.
Natural remedies such as herbs and antioxidant supplements can be used to help liver functions such as detoxification. Homeopathic remedies can also help the body detoxify itself. Please visit this page for more information.
