I don't know about any other state but here in Florida, if you don't get your dog vaccinated at least for rabies, you pay a fine! My dog gets a 3 yr. shot. As far as parvo, I had 3 dogs that came down with it and it was very expensive to treat them but they lived. The first two dogs got a modified live virus and that's where they picked it up. I would suggest using a killed virus instead. but if you choose not to get it at all and your dog comes down with it, it's very painful to watch them suffer, some dogs do not live through it, also, it's very expensive to treat and some people choose not to because they don't have the money.
