Puppies and kittens require several booster vaccinations three weeks apart to protect from viruses common to our area. Missing a vaccination can lead to severe illness which can lead to death. Puppies and Kittens receive some immunity from their mothers milk, but this immunity will only protect for a short period of time. We recommend vaccinating puppies and kittens at six, nine, twelve, and fifteen weeks. Annual vaccines are recommend one year after the final puppy/kitten booster. These are the national vaccine guidelines set by the American Animal Hospital Association (AAHA).
