Are your other dogs older? We went through the Parvo thing last summer. Our puppy got bitten by a rattlesnake, we took her to the vet and they kennelled her between two puppies with Parvo. A week later she came down with it.
We have 4 other dogs, ranging from 1 - 3 yrs old at the time. We physically could not bleach everything inside that may have had the virus on it, as that could be anything we had touched in the entire house. We throughly bleached their toilet area of the yard, with straight bleach, and threw their toys and beds out. I used a bleach solution on the areas of the carpet where she had vomited. We threw out her food bowl, and any other plastic bowls, and bleached the stainless steel ones (then rinsed very well).
Other than that, since the other dogs had been around her for a week, we figured if they were going to come down with it they would no matter what we bleached. Luckily nobody did, they all were up to date on their shots. The puppy made a full recovery. We don't allow anybody else's dogs in our house or yard, and will not for a year.
It really is important to note that vaccines bought from feed stores etc truly are not as effective as those administered by a vet. They do not usually have protection against the most recent strains of the virus, and (unless you go to our incompetent previous vet!) you can be fairly certain that the vaccine has been handled and stored appropriately if sent to a vet's office rather than a store. Our new vet, who is very old school and quite willing to advise us on how to treat conditions at home, will sell us vaccine to administer ourselves rather than us use the feedstore brands.
