• Our 7 mo old Morkie puppy has an elevated BUN and ALT. I read that puppies eating kitten (cat food) can cause kidney and liver problems since they cannot digest the kitten for the same. Our puppy has been getting into the kitten's food quite a lot. Could that be possibly be causing the increase in BUN and ALT. Since reading that, we have no removed his access to the cat's food.

    Hi Richard,
    I recommend that you call and talk to your local veterinarian about your questions. There can be many different causes for these values to be increased which does include what they are eating. The significance of these results will depend on your pet’s age, breed, size, and medical history. Your vet knows your puppy and they can give you the best advice on what is causing his increased values.
