Can a puppy get parvo after its second vaccination?

Answer 1

Yes, it is possible. The vaccine against parvovirus is not considered completely effective in a puppy until two weeks after the last shot is given; since the last shot is generally given when the puppy is 16 weeks old, the puppy can usually be considered protected by the time it is 18 weeks old. If your puppy had not completed the vaccine series, it was still susceptible to parvovirus infection.

Answer 2

Yes, as they usually will not have full immunity until after the 3rd shot. It's the "window of susceptibility". During this time, limit your dogs exposure to other dogs, dog parks, pet stores and the floor of vet clinics.

Answer 3

Yes, I just had a red heeler get it at 13 weeks or ~3 months. We took him to the vet and after two days @ the vet he was able to come home. The vet said this was exceptional most dogs take four days, if they recover at all.

Answer 4

Yes, a puppy can get a parvovirus infection up until 14 days after the last parvo booster shot (usually given at 16 weeks of age). The parvo shot is a vaccine, which is not immediately effective and needs to be boostered several times until the puppy's immune system has built up enough antibodies to protect the puppy.

Answer 5

YES - Parvo virus can mutate into strains that are not covered. The vaccine may also be ineffective if it is outdated, or not kept cold enough. Vaccines can also be rendered ineffective if given before the pup is weaned long enough, as the immunity from the mother's ,milk may override vaccines given too early. And lastly, vaccines must be given at 3-wk intervals between 6 and 16 weeks, then again at 6 months.

Answer 6

Maybe.
