If you’re planning a trip to the dog park or a walk around a crowded park with your new puppy, you might want to wait a few weeks. A Kansas State University veterinarian says taking your puppy out before it has been fully vaccinated for parvovirus could be deadly, especially at this time of year.
“Parvovirus—parvo—is a highly contagious virus
that is something we do see year-round because it is always in the environment, but the Veterinary Health Center has been seeing more cases recently,” said Susan Nelson, clinical associate professor of clinical sciences.
The increased number of cases is because the weather is nicer, which is a better environment for the virus to survive, and owners are taking advantage of the warmer temperatures to take their pets outside and interact with other dogs
. But owners may not realize their puppy is at risk of getting parvo until they are fully vaccinated, according to Nelson.
“We usually see cases in young dogs, primarily puppies, that have had one vaccine
as a puppy but didn’t complete the series or had no vaccines at all,” Nelson said. “This is definitely a preventable disease, so it’s important when you have puppies to get them into your veterinarian starting around 6 to 8 weeks of age for their first vaccine of what is commonly known as their ‘puppy series.’ Then they will need to get that vaccine every three to four weeks and receive their last booster around 14 to 16 weeks of age for the best chance of avoiding parvo and other diseases included in this vaccine series. They aren’t considered fully protected until a few weeks after that final dose at 14 to 16 weeks of age.”
Nelson says the number of shots may concern pet owners, but the protection is vital. A mother gives immunity to her pups through her milk. As long as this immunity is around, it will keep the puppy from responding to a vaccine. While the mother’s protection is good for the puppy, at some point it goes away. If it has already rendered a vaccine ineffective, it leaves the puppy at risk for infection until the next round of boosters. For some pups, mom’s immunity disappears as early as 6 weeks of age, while for others, around 14 to 16 weeks of age. To protect as many puppies as possible, vaccines are started around 6 to 8 weeks of age and ended around 14 to 16 weeks.
