Alrighty so I am a bit concerned about our blue pit, Leo. Last Saturday he had very yellow, liquidy diarrhea and threw up all of his dog food but after giving him a lot of pedialyte and pepto he was fine. However, we still took him to the vet Monday for a fecal sample just to be safe. The tests came out negative for any parasites and for parvo and he was fine the rest of the week. Then this Saturday rolls around and he won't eat or drink, he won't play, he's throwing up everything and having bloody diarrhea. We gave him gatorade and force fed him maple syrup mixed with water and gave him a pedialyte enema and after 24 hours he was eating and playing again. The past 48 hours his stool has been solid but still has sort of a copper/penny smell to it but he's been normal other than that. Should I retest him for parasites and parvo? How long does he need to be symptomless before I should stop worrying? I'm thinking its either hookworms (doubtful because of fecal tests) or that its a reaction to the dose of parvo in his 2nd set of shots? I'm just very concerned and I don't want to lose him =/ our vet doesn't seem concerned and is sort of treating the situation as if I'm just being a hypochondriac so I would really appreciate your guys' input! Thank you!
