My coonhound pup had parvo. She pulled through it after 3 days of hopitalization and iv's. When we brought her home, we kept her littermate away from her so that she wouldn't get it. Also, we fed boiled rice and venison. She came through it as good as new but I wouldn't bring her around other puppies, even once she's better. The problem with parvo positive dogs is that even though they might be better, they are still carriers and can still pass it on. The only way to guard against it is vaccinating but that's not 100%.
