The DHPP vaccine is a combination of vaccines. The name DHPP is an acronym that comes from the viruses it protects against. Distemper, Hepatitis, Parainfluenza, and Parvovirus. It's a vaccine that all dogs should get early on in life and at a regular schedule following.
Canine Distemper Virus
Is a highly contagious virus that affects the respiratory, gastrointestinal and central nervous system organs. Distemper is incurable, often fatal, and dogs that survive usually have permanent; irreparable nervous system damage.
Infectious Canine Hepatitis
Infectious Canine Hepatitis (IHC) is a viral infection of the liver. Infectious Canine Hepatitis (IHC) begins to replicate in the tonsils and from there the virus spreads to nearest lymph nodes, then spreads to the circulatory system. The body's blood supply pushes the virus to various bodily tissues such as the lungs, liver, kidneys, spleen, and eyes resulting in inflammation, bleeding, and even death of bodily tissues. Severe cases may result in death of the dog.
Canine Parainfluenza Virus
Canine Parainfluenza Virus (CPIV) is a highly contagious virus that affects the respiratory system. Parainfluenza suppresses some of the innate parts of the immune system and causes a loss of cilia. Cilia filters dust and other materials from inhaled air before it reaches the lungs. The infection and removal of this filter makes it easier for co-infections like "kennel cough" to occur.
Parvovirus (CPV) is a highly contagious virus that causes a gastrointestinal illness in dogs. Parvo can be deadly to puppies if not treated as soon as possible. Dogs of any age can get Parvovirus, but puppies younger than 6 months are more vulnerable to the virus.
