I had two dalmation/lab crosses that both survived parvo. In fact they were siblings and were completely vaccinated when they got it. But they both lived to the ripe old ages of 11 and 12. I also have a friend whose puppy just went through a bout with parvo and survived. I know at work we use bleach, betamint, betazyme, and virkon. The virkon is supposed to be virualcide (okay I think I just made that word up). I don't like it though because it gets all foamy and soapy. I prefer to use bleach myself but then again I use it at full strength.
