Updated On September 23rd, 2025

Pet's info: Dog | Golden Retriever | Female | unspayed | 1 year and 9 months old | 50 lbs

Hi. I’m wondering about a situation where there was a litter of puppies who contracted parvo. They were sick all over the back yard. This would have been a year ago and now mom is pregnant again. How can I prevent this litter from contracting parvo from my infected back yard? Will her antibodies be stronger dontonher being exposed to the virus last year? Should I get her a parvo shot while she’s pregnant?

Hi. Most likely after that long, ot wouldn't still be in the environment. It wouldnt hurt to definitely clean everything out there really well. As far as vaccines, it is not recommended to vaccinate a pregnant pet or a lactating pet. So to vaccinate mom, it will have to wait until the puppies are weaned. The best way to prevent parvo in the puppies is to keep them.home only, keep a clean area, and begin vaccinating puppies with their veterinarian at 6 to 8 weeks. And then every 3 to 4 qeeks until 16 to 18 weeks old. Good luck.
