Many areas have laws that require dogs and cats (and sometime ferrets) to be vaccinated against rabies. These laws help protect both pets and people from this deadly disease. Locally, dogs and cats require a current rabies vaccination certificate to cross into the United States and dogs require current rabies vaccination to obtain their city dog license. We recommend that all dogs and cats (even indoor ones) be kept up to date on their rabies vaccination because of the potential threat to human health.
