AST in dogs stands for Aspartate aminotransferase (formerly SGOT), an enzyme used in blood tests as a marker for liver damage or disease. It is found in the liver, skeletal muscle, cardiac muscle, and red blood cells. Elevated AST levels indicate that these cells are damaged, allowing the enzyme to leak into the bloodstream.

When should I worry about AST in dogs?

When levels are increased in the blood, it means that the enzymes have leaked out of the liver cells due to cell damage. AST is found in muscle cells as well as liver cells, so an elevation in AST without a similar elevation in ALT may indicate muscle damage rather than liver damage.

How to treat high AST in dogs?

If your dog isn't acting sick, your veterinarian may recommend a therapeutic trial of antibiotics (to rule out a possible infection), antioxidants (such as vitamin E, Denamarin®, or ursodiol (a drug that increases bile flow and decreases inflammation). After a few weeks of therapy, the liver values would be rechecked.

What is AST in a blood test for dogs?

Aspartate aminotransferase is an indicator of damage to muscle (skeletal or cardiac) or liver cells. It is also found in the kidney. This enzyme is present in the cytosol and mitochondria.

What not to feed a dog with high liver enzymes?

What to Avoid:

• Fatty Meats: High-fat meats place additional strain on the liver.
• Organ Meats: Giblets are high in protein and can overburden the liver.
• Onions and Garlic: These vegetables are toxic to dogs.
• High Levels of Salt: Excess salt can strain the kidneys and further harm the liver.

• Cirrhosis.
• Mononucleosis.
• Heart procedures or problems.
• Pancreatitis.
• Hemochromatosis (too much iron in the body)
• Deep burns.
• Seizures.

How do you fix high AST?

Treating high AST levels involves addressing the underlying cause, often through lifestyle changes like a healthy diet (fruits, veggies, whole grains), regular exercise, weight management, avoiding alcohol and smoking, and careful medication use; see your doctor for diagnosis, as severe elevation needs immediate medical help to find serious causes like hepatitis or fatty liver disease.

What dog breeds are prone to liver problems?

Genetic predisposition: Certain dog breeds, including the Doberman Pinscher, Labrador Retriever, and Yorkshire Terrier, carry a higher risk of developing specific liver conditions due to inherited factors.

Can a dog recover from high liver enzymes?

Recovery depends on the extent of liver damage and how soon treatment begins. The liver has remarkable healing abilities when given proper support. Some dogs may need ongoing management for chronic liver issues, but many return to normal or near-normal function with appropriate care.

How fast can liver disease progress in dogs?

Chronic Liver Disease: Chronic conditions, such as chronic hepatitis, cirrhosis, or long-term exposure to low-level toxins, generally evolve over months to years. They can often be insidious, meaning they progress quietly without causing noticeable symptoms until the disease is advanced.

How to bring down high liver enzymes in dogs?

Foods like duck, beef or pork meat should be avoided or reduced a great deal. Dogs with increased liver enzymes should be fed food rich in protein, such as fish, egg or chicken. Vegetables are also a healthy food for the liver, vegetables like broccoli and carrots are highly recommended.

Are dogs with liver disease in pain?

Yes, some dogs may experience abdominal pain with liver failure. Other symptoms include vomiting, diarrhea, lethargy, and collapse.

Can stress cause high AST?

The most common ones are alanine transaminase (ALT) and aspartate transaminase (AST) (also called alanine transferase and aspartate transferase). These enzymes are released into your blood by your liver. If a blood test shows your transaminases are elevated, it suggests that your liver is under stress.

Can dehydration affect AST levels?

In present study, we assessed the extent of elevated liver enzymes; AST and ALT, in severely dehydrated children with AGE. Most of the patients (60, 43.5%) showed temporary isolated AST elevation along with normal ALT level. Concurrent elevated AST/ALT was observed in 22 (15.9%) children.

Can a high AST mean nothing?

Know that having a high level of aspartate transaminase (AST) doesn't necessarily mean you have a medical condition and need treatment. Many factors can affect your AST levels, and approximately 1 in 20 healthy people will have a result outside the normal reference range.

What drugs cause high AST?

Other common medications that may cause elevated liver enzymes include:

• The antibiotics synthetic penicillin, ciprofloxacin and tetracycline.
• The anti-seizure drugs carbamazepine and phenytoin and valproic acid.
• Nonsteroidal anti-inflammatory drugs (NSAIDs)
• The diabetes drugs sulfonylureas and glipizide.

What dog breeds are prone to liver issues?

Certain breeds are predisposed to specific types of liver diseases due to genetic factors. Breeds at higher risk include Doberman Pinschers, Cocker Spaniels, Labrador Retrievers, Bedlington Terriers, German Shepherds, Standard Poodles, West Highland White Terriers, and Skye Blue Terriers.
