Every US state has a 3-year rabies vaccination requirement (see www.dogs4dogs.com/rabies-laws). There are more frequent laws in some localities. Call your local Animal Control to check. Also, the FIRST rabies shot has to be followed by another in one year. Thereafter, it should be every three years. Before your dog gets the shot, I suggest you read this article on protecting your dog from an adverse reaction. http://www.dogs4dogs.com/blog/2010/09/23/rabies-va...
