I've been nervous, too, ever since poor little Madda came down with Parvo. But, Cindy was telling us that she has no idea WHERE Madda got it because Madda never went outside and was never around strange dogs. So, I guess there is really no point in me worrying. All I can do is stay current on all of their shots and keep them away from strange dogs and stray poo in the yard. Whatever is meant to happen, will happen. Of course, I'm sure I'll be singing a different tune if something actually does "happen."
