How to prevent bringing parvo home to my vaccinated dog from the vet?

There is less risk for an adult fully vaccinated dog to develop parvovirus, but it can be a very hardy virus and live for a long time on clothing or shoes. To be safe I would change clothes after coming in contact with the puppy and wash hands thoroughly. You can clean shoes in a mixture of bleach and water (1:32).

No, it is not necessarily safe to go home and handle your animals if you were handling the one infected with Parvo. For instance, in a hospital setting, Parvo infected animals are kept completely isolated from the others and anyone that is handling them has to wear special bioprotective gear to prevent spread of disease. I would recommend that you change out of anything you were wearing that could have come in contact with the dog or the dog's belongings, and clean yourself off thoroughly with a bleach product. The Parvo virus will not be killed by regular antibacterial soap, which is the reason that bleach is the best thing to use in the absence of a veterinary cleaner which the average person does not possess in their home. Hope this helps!

Yes, you should be worried, but if your dog is vaccinated against parvo, then there is no worry. If your dog isn't vaccinated, I would keep a change of clothes to change into in your car when you get home from your boyfriend's place.

Parvo can live in the environment for up to 6 months without proper cleaning, so it can be carried in on your shoes and clothes if you come into contact with the virus. If Tiny is vaccinated, it likely isn't an issue, but if you are interacting with unvaccinated pets or puppies and are concerned, cleaning or changing out shoes/clothes is best to avoid spreading it.

It sounds like you've done a good job disinfecting your home - if the new pup is finished with her vaccinations, the risk should be minimal. To be safe, you could certainly try and keep her in the areas of your home where your previous puppy never spent time or used the bathroom. But from what you've said here, it seems unlikely that Kiki would get sick - the parvo vaccine is usually very effective, so most cases that I see are in unvaccinated pups.

Parvovirus (CPV) is very hardy. It is capable of surviving for months in the environment, even through the winter. Infected dogs can shed huge amounts of the virus, making it difficult to disinfect an area once it has been exposed to an infected dog. If you have parvovirus on you or your clothes you can certainly transmit it to your car or other places. Disinfectant wipes are not likely to do the trick. CPV is resistant to most household cleaning products with the exception of bleach. Cleaning with a solution of one part bleach mixed with approximately 30 parts water is an acceptable method for disinfecting any indoor area (including bedding, food/water bowls, and all surfaces). Hope this helps.

It is unlikely that your home will have parvo in the environment. It can survive for a long time in soil, but in the home you would be looking at approximately 3 months after an infected dog had been present. You would have to buy special cleaner that is sensitive to parvo, most vets have this. Luckily nowadays parvo is quite rare, it is good that you are so concerned but dont think it is necessary to clean your shoes all the time. You could just remove them in the porch.
