Canine parainfluenza virus (CPIV) is a highly contagious respiratory virus and is one of the most common pathogens of infectious tracheobronchitis, also known as canine cough.1 Although the respiratory signs may resemble those of canine influenza, they are unrelated viruses and require different vaccines for protection.
CPIV is excreted from the respiratory tract of infected animals for up to 2 weeks after infection and is usually transmitted through the air.1 The virus spreads rapidly in kennels or shelters where large numbers of dogs are kept together.2
