Last month, we went more into depth on the first half of what DA2PP vaccine means. This time we’ll be taking a look at what the two 'Ps' stand for.
D- Canine Distemper Virus
A2- Adenovirus-2
P- Parainfluenza
P- Parvovirus
Parainfluenza, the dog flu, is another virus that causes a highly contagious respiratory infection. It also causes a cough that is easily mistaken for kennel cough, but is in no way related. Infected animals can be contagious for up to two weeks after infection, and it’s usually spread through the air. Symptoms will include a dry or moist cough, a low-grade fever, nasal discharge, lethargy, and loss of appetite(1).
Nearly all dogs that are exposed to parainfluenza become infected; however only 80% will show clinical signs, but all infected dogs will shed the virus. Thankfully, not many deaths occur from this disease, yet it can pave the way for other respiratory problems(2).
Finally, we come to parvovirus. Parvo as it is commonly known is a serious disease and can cause death within 2 days of the onset of symptoms. It is highly contagious and targets the gastrointestinal tract. Symptoms include: lethargy, loss of appetite, fever, vomiting, and severe bloody diarrhea. It’s spread by direct contact with the sick individual, or contaminated feces, environments, or people. Unfortunately it can remain viable within the environment for extended periods of time(3).
While parvo can affect all dogs, unvaccinated dogs and particularly puppies under four months old are the most susceptible. There is no “cure” for parvo, but with aggressive supportive care up to 90% of infected dogs can survive. Even aggressive supportive care cannot guarantee the outcome. It’s best to have your dog vaccinated.
We hope this series has cleared up some of the mystic on this particular vaccine. Until next time!
