Has anyone ever heard of this or am I just paranoid? My husband said that a girl at work told him that she had pups for sale and someone came to look at them and handle one well they had a dog at home that had parvo and I guess they didn't know it and transfered it to the pup they handled and it died. Could this happen? I have someone coming to look at puppies tomorrow and put a deposit down. I am going to ask them to wash thier hands before they handle any puppies. I hope that isn't offensive to any one but I can't take any chances with these babies. What do you all think?
