"The updated Rabies Control Act has new rules passed by the State Board of Health that allow for a longer interval between rabies vaccinations for dogs and cats. The new rules will become effective January 1, 2010.
If a three-year vaccine is chosen, the pet will be required to be revaccinated three years later."
