Liver Problems in Dogs: Signs, Causes, Tests and Care
If you are reading about liver problems in dogs, your veterinarian is the best first step. This guide explains what owners commonly see and what to do next. It does not diagnose or prescribe.
Liver problems in dogs range from mildly raised liver enzymes found on a routine blood test to serious dog liver disease that causes yellow gums, vomiting and confusion. The liver filters toxins, helps digest food, and makes proteins the body needs, so problems can show up in many ways.
The liver can often repair itself if the cause is found early. This guide explains common signs and causes, how vets test for liver problems, and how diet and care support a dog with liver disease.
Important: Yellow gums, skin or eyes (jaundice), confusion, wobbling or seizures, vomiting with lethargy, or a swollen belly need a vet today. If your dog may have eaten xylitol, sago palm, wild mushrooms, moldy food or human medicines, call your vet or a pet poison line now: ASPCA Animal Poison Control (888) 426-4435 or Pet Poison Helpline (855) 764-7661 (a fee may apply).
What Liver Problems in Dogs Are
Acute Liver Injury
Sudden damage from toxins, infections or medicines. Can be life-threatening but may recover with fast treatment.
Chronic Liver Disease
Ongoing inflammation (hepatitis), copper build-up in some breeds, or scarring over months or years.
Raised Liver Enzymes
Blood test results that show the liver is stressed. They have many causes, some outside the liver, and need follow-up tests.
Shunts in Young Dogs
A blood vessel that bypasses the liver (portosystemic shunt), seen most in small breeds, causes poor growth and odd behavior after meals.
Signs of Liver Problems in Dogs
Jaundice
Yellow gums, whites of the eyes, or skin on the belly and ears.
Stomach Signs
Vomiting, diarrhea, poor appetite and weight loss. See dog vomiting.
Thirst and Urine
Drinking and peeing more, and dark orange urine.
Behavior and Belly
Confusion, pressing the head against walls, wobbling, seizures, or a swollen belly.
How Liver Disease Develops
Toxins
Xylitol, sago palm, certain mushrooms, blue-green algae, moldy foods and some human medicines, including acetaminophen, can badly damage the liver.
Infections
Leptospirosis (spread by wildlife urine and puddles) and canine adenovirus can attack the liver. Vaccines protect against both.
Breed and Genetics
Bedlington terriers, Labradors, Dobermans, West Highland white terriers and some other breeds are prone to copper-related or chronic hepatitis.
Other Illness and Age
Hormone diseases such as Cushing’s and diabetes, pancreatitis, and liver tumors in older dogs.
Dog Liver Problem Treatment and Diet
Tests
Blood and urine tests, a bile acid test, ultrasound, and sometimes a liver biopsy help find the cause.
Treating the Cause
Removing toxins, treating infections, managing copper, or surgery for shunts. Some dogs need fluids and hospital care.
Diet
Your vet may recommend a liver-support diet with high-quality protein in the right amount. Do not change diets or add supplements without your vet.
Supplements
Some vets use liver-support supplements alongside treatment. Ask before giving any, as some can interact with medicines.
