Core vs. Noncore Dog Vaccinations Vaccinations for pets are split into two general categories: core vaccines and noncore vaccines.  Core Vaccines Core vaccines are required for all dogs and puppies. Core vaccines include: Canine distemper/adenovirus (hepatitis)/parvovirus vaccine (given as one vaccine called DAP or DHP) Canine rabies vaccine Noncore Vaccines Noncore vaccines (lifestyle vaccines) are considered optional and given based on factors such as your pet’s lifestyle and geographic location. Several noncore vaccines protect against highly contagious or potentially life-threatening diseases. To determine which lifestyle vaccines are appropriate for your pet, your vet will look at a variety of factors, including: Geographic location and risk of disease in these areas Whether your pet goes to doggy day care, dog parks, boarding or grooming facilities Whether your pet’s lifestyle includes traveling, going on hikes, or being exposed to wilderness or bodies of water Overall health of your pet Noncore vaccines include: Bordetella Bronchiseptica vaccine Parainfluenza vaccine (often combined with either the Bordetella or the DAP vaccines) Leptospirosis vaccine Lyme vaccine Canine influenza vaccine (H3N2 and/or H3N8) KM GLOBAL ANIMAL HOSPITAL Reference : Vaccinations Schedule for Every Lifestage | PetMD read more
