That poor pup needs to be evaluated by a vet ASAP before it becomes dehydrated
Well, he's not off to a very good start is he? You don't say how old this guy is...It's possible that he IS too young to be able to eat, but can only drink the milk & should still be nursing........Either way, You need to get this Puppy to your Vet ASAP & have him evaluated to make sure this isn't the beginning of any serious illness.....The sooner the better.....Karla
