Well Snoopy has returned to normal now. He has never had diarrhea, but the vomiting didn't start till I started giving him high quality treats from the holistic pet store and the vomiting stopped once I stopped giving the treats. Because the other time he had a vomiting spell it was right after giving those high quality treats. Then it started again once I gave him that bone, so I agree with vet because he said the treats from that store are most likely to rich and are upsetting his stomach.
