When should my rescue puppy get parvo shots? What's the schedule?

Updated On September 23rd, 2025

Hello I work with a rescue and we get a lot of parvo pups. My question is as long as pups are still with mom should we start pups on shots at 5 wks? And if we do then do we do shots at 5,7,9 wks of age? Thank you

Giving a shot before six weeks is not necessary and there is not sufficient evidence that this is helpful. They should start at six weeks and get a booster every week until they are 18-20 weeks of age. The last one is the most important, because they will most susceptible around 16-20 weeks of age. If you happen to get a puppy in that is over 16 weeks of age, then they should receive an initial vaccine and a booster 2-4 weeks later. These are the current shelter guidelines and what I've done with success at other shelters. The most important thing for prevention of parvo is sanitation and quarantine if you are taking in Parvo positive/suspects. I hope that helps and you can get this issue more under control. I definitely understand how miserable these outbreaks can be.
