What Are The Symptoms Of High Alkaline Phosphatase In Dogs

Dogs are wonderful companions, and as pet owners, it’s our responsibility to ensure their well-being. One crucial aspect of a dog’s health is monitoring their blood chemistry, including the levels of substances like alkaline phosphatase. In this article, we will explore the symptoms of high alkaline phosphatase in dogs and what you can do to help your furry friend.

What is Alkaline Phosphatase?

Alkaline phosphatase, often abbreviated as ALP, is an enzyme found in various tissues throughout a dog’s body. It plays a crucial role in several physiological processes, including bone formation and liver function. While it’s normal for dogs to have some ALP in their bloodstream, abnormally high levels can be a cause for concern.

Importance of Alkaline Phosphatase in Dogs

Before diving into the symptoms of high alkaline phosphatase, let’s understand why this enzyme is important. ALP helps in the development and maintenance of healthy bones in dogs. Additionally, it aids in the digestion of certain nutrients, particularly in young puppies.

Symptoms of High Alkaline Phosphatase in Dogs

When a dog’s alkaline phosphatase levels become elevated, it can indicate an underlying health issue. Here are some common symptoms to watch out for:

Digestive Issues

Dogs with high ALP may experience digestive problems such as diarrhea or vomiting. These issues can be persistent and affect their overall well-being.


Lethargy or a lack of energy is another potential sign. Your dog may appear tired and unwilling to engage in activities they once enjoyed.

Loss of Appetite

A decrease in appetite is often associated with high ALP levels. If your dog suddenly loses interest in food, it could be a cause for concern.


Jaundice, characterized by yellowing of the eyes and skin, may occur in dogs with elevated alkaline phosphatase. This indicates a potential liver issue.

Bone Problems

Since ALP is involved in bone health, dogs with high levels may experience bone-related problems, such as pain or difficulty moving.

Behavioral Changes

Unexplained behavioral changes can also be a sign. Your dog might become irritable or anxious due to discomfort.

Other Potential Symptoms

In some cases, other symptoms like increased drinking and urination or weight loss may accompany high ALP levels.

Diagnosing High Alkaline Phosphatase

If you observe any of these symptoms in your dog, it’s essential to consult your veterinarian. They will perform a thorough examination and may request blood tests to confirm elevated ALP levels.

Common Causes of Elevated Alkaline Phosphatase

Understanding the root cause of high ALP levels is crucial for effective treatment. Some common causes include liver disease, bone problems, infections, or even certain medications.

Treatment Options

Treatment for high alkaline phosphatase levels depends on the underlying cause. It may involve medication, dietary changes, or addressing any specific health issues your dog is facing.

Preventing High Alkaline Phosphatase Levels

While not all cases of high ALP can be prevented, maintaining a healthy diet and regular exercise can contribute to overall well-being. Regular check-ups with your veterinarian can also catch potential issues early.


In conclusion, high alkaline phosphatase levels in dogs can be a sign of underlying health problems. It’s essential to be vigilant and seek veterinary care if you notice any concerning symptoms. With early diagnosis and proper treatment, your beloved pet can enjoy a happy and healthy life.
