My dog had parvo when she was less then 3 months old. She lived! She is now 11 months old. That was 8 months ago. I am getting a pup on the 5th of June this year. I went outside and sprayed the back year with 1 part bleach to 30 part water all over the back yard. Will that get ride of it in the back yard? It has been 8 months ago that my other dog had parvo. Is it gone from the inside of my home? What else should I do?
