The DHPP vaccine for dogs is a combination vaccine that protects against several diseases, including distemper, hepatitis, parainfluenza, and parvovirus. It is commonly referred to as a distemper or a distemper-parvo vaccine. The DHPP vaccine is a core vaccination that is needed by all dogs, and puppies can be started on this vaccine by 6 weeks of age. They should then receive a high titer low passage booster every 3-4 weeks until they are approximately 16 weeks old. Once a properly vaccinated puppy reaches adulthood, it should receive boosters every 1-3 years as determined by a veterinarian. The DHPP vaccine is considered vital to a pets health based on exposure risk, the severity of the disease, and its transmissibility to the human population.
