Please take your puppy to the vet ASAP!!
ParvoVirus may or may not be the cause but without your veterinarians help, the dehydration if left untreated can lead to shock and eventually death.
Dr Carol Osborne, DVM
Your puppy is in trouble! Please, get to a Vet immediately....... Dehydration from the diarrhea & vomiting alone, can kill a puppy quickly...... Get him some help, NOW!
