Poor little guy isn't moving much, clearly not feeling well as he isn't eating his food or treats, and I get get him to take his meds

but he is drinking his water... I called the vet, as he is already coming back to check on him with the lab results in a few days, but I'm worried the little guy won't make it.... Say a prayer for him as he has been a very good dog that claimed me in either 92 or 94...
