Agree with Muttmom! Cannot wait! ER Pet hospital! If doc rules out parvo, then there's things I would do. When my boy is down, I give him 2T plain yogurt a.m. & p.m. before food. I will pray for your pup & you!
This is an emergency. Vet---NOW. If he dehydrates he could die. Could be the food, could be parvo.
