Puppy Parvo: When is it safe for my vaccinated puppy to go home?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | unspayed | 3 months and 7 days old | 1.5 lbs

Due to sisters dog getting and surviving Parvo 6 months ago her new Chihuahua puppy is staying with me. We were told she had her 1st vaccination at 5 wks but did not have proof so are not counting it. She got her 1st vaccination at 8 wks, 2nd 3 wks later and will be getting her 3rd tomorrow. Now is where I am getting different answers on when she can go home with my sister. Some say in 10 days, some say she need 1 more vaccinations and others say 2 more vaccinations. Please help.

Hello, congratulations on your new puppy. The reason why you are getting different opinions is because there isn't a correct answer to avoid the risk of exposure. Regardless of the time you chose to bring her to your sisters, there will be a chance she could contract parvo from the environment. So how do you decrease this possibility. First, understand that Parvovirus is a strong virus that can survive in the environment for long periods of time. The virus is actually most susceptible to bleach. Now, cleaning the entire house with bleach is not feasible, but what ever can be cleaned with bleach should. Your sister should get rid of any old toys, bedding, clothes from the puppy that had parvo, and use new things for this new puppy. Bedding and other washable materials should be washed with hot water at least 2-3 times prior to the new puppy coming. A fully vaccinated puppy (has had 3-4 booster of the parvo vaccine combo) and is older than 16 weeks will have a significantly lower risk of becoming ill. As long as all of these steps are taken, then Bella should be very unlikely to become ill. However, that risk, will never be zero. Hope this helps and best of luck.
