keep it hydrated .....good luck with the smell! i would go to my ex wifes vet clinic and they would have dogs there that had parvo crappin all over the place i clearly remember the smell
dont give up though dude once a dog pulls through something like that you can see it in thier eyes how they worship you for stickin with em . my dogs are like kids to me id pay whatever to fix em if they were hurt or sick
