What Are the Alkaline Phosphatase Levels in Dogs?

Alkaline phosphatase (ALP) is a liver enzyme found in the liver, bones and kidneys. In dogs, the normal or reference range of ALP levels can vary depending on several factors such as age, breed, and overall health status.

The reference ranges may also differ between different laboratories. Here is a general range for ALP levels in dogs:

Adult dogs: 20 - 150 international units per liter (IU/L)

Puppies: Up to 350-400 IU/L with lower values as the puppy matures.

Elevated ALP levels can be due to a number of reasons including liver disease, bone disorders, certain types of cancer, and conditions that affect bile flow. Low levels of ALP are less common and can be associated with malnutrition or certain genetic conditions.

It's important to note that the ALP level alone is not diagnostic and should be interpreted in the context of a dog's overall health, symptoms, and other relevant laboratory findings. If you are concerned about your dog's ALP levels or observe any unusual symptoms, it is advisable to consult with a veterinarian for proper evaluation and guidance.
