your best bet with the pup that doesnt have parvo send him to a friends or family members house that way he wont contract parvo
spray everything with the bleach solution
NO!!!!!!! If he has been exposed to Parvo he will carry it over. You can also carry Parvo on your clothes. Wash everything you have and quarantine the puppy. Get some overalls and rubber boots Wear those around your dogs and keep the bleached. I killed every bit of grass in my yard and had to spread hay because of the mud. Parvo is very contagious and should be treated like a plague. It can be carried on clothes, shoes and anything else. Make sure the puppy has it's Parvo vaccine and watch it close. Get to the vet at the first sign of Parvo. Keep every dog where it is. They can have it and not show signs plus it can be on their hair. Wash your dogs often as well. After you have bleached everything and kept the dogs isolated for four week I think you are in the clear. The incubation period is 7-14 days.
I HATE PARVO!!!!!!
