Our recommended vaccination schedule, once the puppy or kitten series of vaccinations is complete, is an annual booster for canine distemper/parvovirus combination for dogs and feline distemper combination for cats. Rabies is recommended every other year for the average animal. Those with a higher risk, such as hunting dogs or farm dogs, we recommend annual boosters. Those with very low risk, dogs that do not leave the house except on a leash, the booster can be extended to three years. See our vaccination schedule here.
