What Causes High Liver Enzymes in Dogs

Welcome to our comprehensive guide on high liver enzymes in dogs. If you’ve recently received the concerning news that your beloved canine companion has elevated liver enzymes, it’s natural to have questions about the causes and solutions. In this in-depth article,

we will thoroughly explore the multifaceted aspects of high liver enzymes in dogs, providing valuable insights into not only the causes but also the symptoms, diagnosis, treatment, and prevention of this health concern.

What Are Liver Enzymes?

Before delving into the complexities of high liver enzymes, it’s essential to have a fundamental understanding of what liver enzymes are. Liver enzymes are specialized proteins produced by the liver, which play a pivotal role in an array of bodily functions. These functions encompass digestion, metabolism, and detoxification processes vital to your dog’s overall well-being.

Causes of High Liver Enzymes in Dogs

Now, let’s embark on a comprehensive exploration of the myriad factors that can lead to elevated liver enzymes in dogs:

Food Allergies: Dogs can develop allergies to specific foods, sparking an inflammatory response in the liver and consequent elevation of enzyme levels.

Medications: Certain medications, especially when administered over extended periods, such as antibiotics or pain relievers, have the potential to impact liver function.

Infections: Bacterial or viral infections, including hepatitis, can exert a detrimental effect on the liver, causing a surge in enzyme levels.

Toxic Substances: Ingestion of toxic substances, whether they be certain plants, chemicals, or excessive alcohol, can inflict harm on the liver.

Obesity: Canine obesity can culminate in fatty liver disease, a condition that significantly increases liver enzymes.

Genetics: Some dog breeds possess a genetic predisposition to liver issues, making them more susceptible to enzyme elevation.

Pancreatitis: Inflammation of the pancreas can indirectly impact the liver, leading to enzyme elevation.

Gallbladder Disease: Issues like gallstones or gallbladder dysfunction can indirectly affect liver function, thereby elevating enzyme levels.

Trauma: Severe abdominal injuries or trauma can directly cause liver damage, leading to enzyme elevation.

Cancer: Whether benign or malignant, liver tumors can lead to the elevation of liver enzymes.

Poor Diet and Nutrition: A deficiency in essential nutrients can strain the liver, potentially resulting in enzyme elevation.

Toxic Foods: Specific human foods, such as chocolate, grapes, or onions, are highly toxic to dogs and can inflict severe harm on the liver.

Pre-Existing Liver Diseases: Dogs with pre-existing liver conditions like cirrhosis or hepatitis may experience a further elevation of liver enzymes.

Recognizing the Symptoms

It is imperative to be vigilant for signs and symptoms that may indicate elevated liver enzyme levels in your dog. These symptoms can include vomiting, diarrhea, jaundice (the yellowing of the eyes and skin), lethargy, or a loss of appetite. If you observe any of these warning signs, it is essential to promptly consult your veterinarian.

Diagnosis and Treatment

To determine the underlying cause of high liver enzymes, your veterinarian may perform a series of diagnostic tests, which can include blood tests, ultrasounds, or liver biopsies. Treatment options are contingent upon the specific cause but can involve dietary modifications, medication regimens, or, in certain instances, surgical intervention.


As the age-old adage goes, “Prevention is better than cure.” To safeguard your dog’s liver health, ensure they receive a well-balanced diet, regular exercise, and protection from toxic substances. Regular check-ups with your veterinarian serve as a crucial proactive measure to detect potential issues in their early stages.


Q1: Can high liver enzymes in dogs be reversed?

A1: The reversibility of high liver enzymes depends on the underlying cause. In many cases, with proper treatment and lifestyle changes, it is possible to manage or reverse the condition.

Q2: Are there specific foods that promote liver health in dogs?

A2: Yes, there are specialized diets designed to support liver function in dogs. Consult your veterinarian for tailored dietary recommendations.

Q3: Can high liver enzymes be fatal in dogs?

A3: In severe cases, elevated liver enzymes can lead to serious complications. Timely diagnosis and appropriate treatment are essential to improve the prognosis.


In conclusion, high liver enzymes in dogs can stem from a myriad of underlying causes, spanning from food allergies to liver diseases. It is of paramount importance to collaborate closely with your veterinarian for a thorough diagnosis and a well-structured treatment plan. By prioritizing your furry companion’s well-being and taking proactive steps to protect their liver health, you can significantly contribute to their overall happiness and longevity.

If you suspect that your dog may be suffering from high liver enzymes, do not delay. Schedule a veterinary appointment promptly to provide your loyal companion with the best possible chance of a healthy and joyful life.
