How long does the rabies vaccination last?

According to Fun Times Guide, rabies vaccinations are considered good or up to date for one to three years, depending on the type of vaccination administered to the animal.

The type of rabies vaccination administered depends on location. For example, one city may require a yearly vaccination while another city may only require a three-year vaccination. According to the American Humane Association, the first and second rabies shots are always one-year shots. Pet owners can choose to switch to a three-year rabies vaccination or continue with a yearly vaccination after the first two shots, provided the three-year shot is an available option.
