Check with your veterinarian about the right vaccine and vaccination schedule for your dog. In many areas of the country, itâs mandatory that all domestic dogs and cats are vaccinated after the age of three months. Vaccinating your pet not only protects him from getting rabies, it protects him if he bites someone. Dogs who have bitten humans are required to be confined for at least 10 days to see if rabies develops, and if the animalâs vaccination records are not current, a lengthy quarantine or even euthanasia may be mandated. If youâre not sure of the laws in your town, consult your local animal affairs agency.
