I don't know about that ..this is what my vet has said and I also got from a Parvo WEBSITE "Puppies receive antibodies against parvo and other diseases from their mother before and shortly after birth. These maternal antibodies provide some protection during the first 8 to 12 weeks of life before disappearing from the puppy's body."
"Isolation of puppies until they can receive a full series of vaccine appears to be the best way to insure their future." |
