None of my dogs have gotten vaccinated for anything after the round of puppy shots. After having a severe reaction to a rabies shot by one of my dogs I dropped that one too. We live in the country and in all these years none of my dogs have ever picked up anything. After discussing my feelings with my vet she no longer sends reminder cards for the shots and respects my decision. Even if they need treatment for something she won't try to push the vacs on them. I bring in a stool sample yearly just in case but they are always negative.
