I adopted a puppy from the shelter Monday, her first vet visit was that same day. He said she had Coccidia and possibly worms and gave meds. She started having diarreah vomiting fever and listlessness the next day. We rushed her back and they said possibly Parvo. Hey kept her in hosp. over night on IV, the next day, after having put out close to 700.00 they said I should take her home if I couldn't pay more(which I can't) her insurance won't kick in for 14 days I'm not even sure it is Parvo, but she is deteriorating with blood in stools now, advice?
