Hello, I am a new member and I have a question. I had two dogs that I got off of craigslist. The person that sold them to me said they had all their shots and were good until a year old. Of course I believed them , my family was going threw we had just lost a child to SIDS. One day they were playing with us the next they were gone and it has been about two months and we decided to adopt another dog. This dog is 7 months old , UTD on all shots and has even had 4 doses of the parvo vac as a smaller pup. How great are the chances of him getting parvo? Sorry if this is a stupid question.
