Hi Kerri - I just read your post about your dogs coming in contact with parvo.
Please check out this site
www.ambertech.com. I lost a puppy back in february due to parvo. I am getting my new puppy Monday. I'm using there product called Parvaid on my new puppy as a precautionary action. One thing you said that kinda scares me was the fact that your vet wants to give the parvo booster. If your dog would become infected with parvo and you give them this shot it makes the parvo much worse. You can read about it on this site. Another member here lost a puppy to parvo and she is currently useing this product. I hope she sees this posts and responds how it is working for her new puppy. I also bought a product called Kennel Kare by the gallon. It's proven to kill the parvo virus. I have used it on everything. Lets just say my spring cleaning got done a little early this year. I hope everything works in your favor.
