Your dog's vaccine schedule may vary depending on the type of vaccine given [attenuated-live (weakened, but live germ), inactivated (killed germ), and recombinant], and the injection route (SC, intra-nasal, intra-oral). Each dog must be evaluated and a plan formulated on an individual basis to provide the best protection for your pet. While vaccination generally provides good protection, it does not guarantee complete immunity due to several factors that can affect efficacy. No vaccine achieves 100% protection.

Core Vaccines: Recommended for all pet dogs as diseases can cause significant infection and/or death unless there is a specific medical reason not to vaccinate. These diseases are widely distributed.
Rabies
Rabies virus is transmissible to humans and other mammals (zoonotic)
Vaccination required by AZ law starting at 3 months of age
DA2PPv—combination vaccine includes
Distemper virus
Adenovirus type 2
Cross-protects against Adenovirus type 1 which causes infectious canine hepatitis
Type 2 causes tracheobronchitis
Parainfluenza (tracheobronchitis)
Parvovirus
Non-core Vaccines (optional): Recommended based on your dog's disease risks (environment, lifestyle, and life stage)
Bordetella
Caused by the bacterium Bordetella bronchiseptica
Also known as kennel cough or infectious tracheobronchitis
Common in dogs exposed to kennel or boarding situations
Leptospirosis
This should be considered for all dogs since cases are increasing
Contagious to people (zoonotic)
Lyme disease
Transmitted most commonly by the Ixodes tick, including the black-legged tick
Western black-legged tick (Ixodes pacificus) is found in the higher elevations of the Hualapai mountains (Mohave County) Arizona
Canine influenza—vaccine covers
H3N2
H3N8
Rattlesnake toxoid
Vaccine developed from western diamondback rattlesnake (Crotalus atrox) venom
Lack of peer-reviewed published data demonstrating that it cross-protects against other pit viper envenomations
