I'm so worried .. We purchased pup on sat and today is Thursday he stopped eating anything Tuesday ... He ate a bite of salmon last night and won't eat it today . We go to vet Saturday for last shots.. Just worried to death about him. He is still active a big size for a small puppy and he is drinking water... Frequently ... Why won't he eat ?? Nothing we tried same food as breeders had we tried turkey warm water ... Even tho he is still active he is starting to look skinny and moving slower than yesterday .
