rhe only thing i know about parvo is that cody had it. he was 9 months old....was an indoor dog with a yard of his own....hadn't been around other dogs since he was a pup in school.....one day he puked. about 2 hour later he puked again. an hour later again, 30 minutes again, we gave him an ice chunk, he puked when he licked it.....then he ran to the front and shot poo out his butt like a hose.....he rush him to the ER, and it was parvo. the poo turned into strictly BLOOD that was shooting out of his butt, up to 3 feet....and he puked blood as well. it took a week to just gwet him under control....ano ther week to take home.....and about 2 weeks of nothing to make sure he was okay......but that was after thousands of dollars of vet bills! nasty thing, but im glad he made it!
