My puppy has high ALP levels. Is this normal for a growing dog?

Updated on September 23rd, 2025

Pet's info: Dog | Golden Retriever | Female | unspayed | 8 months and 20 days old | 45 lbs

Luna's Alkaline Phosphatase levels are 350 (normal range is 3-73). The vet has suggested a low carb diet and prescribed Demanarin capsules and Vitamin B supplements. What could be the reason of the elevation?

She is a puppy. An elevated ALP is normal in puppies. ALP can go up because of liver problems, but also increases during bone growth. I see this elevation in about 80% of puppy bloodwork. I do not treat this as it it is not a problem and the value becomes normal when they stop growing. If there are other liver values elevated, then I am concerned, but ALP alone is not generally a problem.

Per IDEXX, one of the largest veterinary pathology services in the United States, ALP values in puppies can be elevated 4 times normal (which is about where Luna is.)

Denamarin, Vitamin B, and a low-carb diet will not hurt Luna, but they probably won’t change the ALP either.

Best wishes to you and Luna.

    Hi there and thank you for using Pet Coach to address your concern. The ALP being elevated in a young puppy like this is normal and to be expected. Growing puppies will typically have an elevated level due to bone growth. This is nothing to be concerned about. I would follow the recommendations for treating the symptoms as your vet should have recommended. If you have any other questions or concerns, please do not hesitate to contact me. I am also available via consultation if needed.
