What causes increased liver enzymes in dogs?
In terms of primary liver issues, ingestion of certain toxins or chronic inflammation of the liver (due to infection, an over-reaction of the immune system, genetic disorders, etc.) tend to create the most significant ALT elevations.
Why would liver enzymes suddenly increase?
Elevated liver enzymes often indicate inflammation or damage to cells in the liver. Inflamed or injured liver cells leak higher than normal amounts of certain chemicals, including liver enzymes, into the bloodstream, elevating liver enzymes on blood tests.
What foods can cause elevated liver enzymes in dogs?
“Things like organ meats and fish contain higher levels of certain compounds (purines, some of the amino acids) that can be particularly harmful for dogs with bad liver disease.
What is the most common reason for elevated liver enzymes?
The most common causes of elevated transaminase levels are nonalcoholic fatty liver disease and alcoholic liver disease. Uncommon causes include drug-induced liver injury, hepatitis B and C, and hereditary hemochromatosis. Rare causes include alpha1-antitrypsin deficiency, autoimmune hepatitis, and Wilson disease.
How long can you live with elevated liver enzymes?
Aspartate Transaminase (AST): Very high levels of AST (more than 10 times normal) are usually due to Acute Hepatitis, sometimes due to a viral infection. With acute Hepatitis, AST levels usually stay high for about 1-2 months but can take as long as 3-6 months to return to normal.
When should I stop taking elevated liver enzymes?
If the levels of transaminases increase to more than 3 times baseline values, discontinuation of the drug should be considered. Clinical correlation with worsening of underlying disease, as well as exclusion of alcohol abuse and drug interactions, should be done before attempting permanent discontinuation of the drug.
What does it mean when your dog has elevated liver enzymes?
Liver enzymes present in your dog’s blood at higher than normal levels are a sign of liver disease and poor liver health. Damaged liver cells leak enzymes. The greater the cellular damage, the higher your dog’s enzyme blood count will be.
Why does my dog have a wonky liver?
The usual culprit is an enzyme called Alkaline Phosphatase, or Alk-Phos, or Alk-P. I commonly see this enzyme rise in older dogs that have no symptoms. The other liver enzymes always seem to be behaving – it’s just this one that’s wonky.
Where are ALT enzymes located in a dog?
Like AST, the ALT enzyme resides within the dog’s liver cells and is released into the blood with cell damage. Unlike AST, it is fairly specific for liver damage, as it is not produced by other organs in the dog’s body. Normal range is considered to be 5 to 107. Off the charts range is 2,000 to 4,000+ ALKP (or ALP) (alkaline phosphatase).
What does it mean when a dog has high ALT?
ALT (Alanine aminotransferase ): ALT is an enzyme that is present in the liver, kidneys, and intestines. High ALT in dogs can be an indicator of liver cell damage, so it should always be a sign to look deeper for serious liver damage. ALP (Alkaline phosphatase): ALP is an enzyme that is found in highest concentration in the liver and the bone.
Where are liver enzymes highest in young dogs?
Liver Enzymes. The levels of this enzyme are highest in the bone and the liver. Basic phosphatase is a homodimeric enzyme that is high in young fast growing animals, so it’s not unusual to see elevated ALP in young dogs. But whatever your dog’s age, if ALP is elevated, ask your vet to investigate the reason.

Can a dog with renal failure have normal liver enzymes?
Patients with renal failure and skeletal or muscular diseases can actually have normal GGT levels so GGT testing can also help exclude those diagnoses. Here’s an example of a healthy dog’s liver enzyme results, showing all enzymes including GGT well within normal ranges. Keep in mind some of the things that might affect your dog’s liver.
