What is a DHPP vaccine?
DHPP is a combination vaccine that protects dogs against distemper, hepatitis, parainfluenza, and parvovirus, considered a core vaccine in canine medicine.
DHPP stands for a four-in-one vaccine that protects dogs from four separate viral diseases. Each letter represents one disease: D for distemper, H for hepatitis, P for parainfluenza, and the second P for parvovirus. Veterinarians classify DHPP as a core vaccine, meaning it is recommended for all dogs because these viruses are widespread, serious, and potentially fatal.
Canine distemper attacks the respiratory, gastrointestinal, and nervous systems and historically had high mortality rates. Infectious canine hepatitis damages the liver and kidneys. Parainfluenza is a respiratory virus that contributes to kennel cough. Parvovirus causes severe vomiting, diarrhea, and dehydration, particularly in puppies and unvaccinated dogs.
Puppies typically receive DHPP in a series of shots starting at 6 to 8 weeks of age, with boosters every 3 to 4 weeks until 16 weeks old. Adult dogs receive a booster at one year and then every one to three years, depending on the vaccine formulation and your veterinarian's recommendation. Some vaccines labeled DHLPP include leptospirosis as a fifth component, though leptospirosis is considered non-core in many regions.
Because DHPP protects against diseases that remain common in the Denver area, veterinarians here strongly recommend this vaccine as part of routine preventive care for all dogs.
