Ah, I'm sorry to hear. So the vet did some lab work and found a raised level of a kidney test? So, he is having some issues with kidneys? What did vet say about that? Any strategies? I know diet an play a role. We had a great person here who always answered questions about dogs with kidney issues. Maybe I'll send them a note to see if they can help. but it sounds like you've notified your vet. I'd worry most about keeping him hydrated. Give us an update with what is going on!
