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

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.
