The problem is, he is only 2 pounds so they have a less of a chance when they are smaller dogs. He has is pretty bad and there is no improvement, he is just getting worse. MY vet see's parvo everyday and I really believe him when he says that the "humane" thing to do is to put him down. But we will wait the rest of the day. Trust me I want to keep fighting, but I also don't want to drag it out and make him suffer more. It's a hard decision
