Canine Parainfluenzavirus – (part of DAPP vaccine)

This virus is one of a group of agents that causes infectious tracheobronchitis and laryngitis (inflammation of the airways), commonly known as “kennel cough” in dogs. Dogs that are exposed to other dogs (such as in a kennel or dog park) or are stressed for any reason may be more susceptible to infection. This virus attacks the specialized cells in the respiratory tract that would normally defend against harmful irritants, viruses, and bacteria. It can take 4-10 days after being infected for the dog to display symptoms. Symptoms can include a mild productive or non-productive cough but can lead to loss of appetite, fever, and lethargy if a secondary bacterial infection takes advantage of the weakened immune system. Treatment may include a cough suppressant and/ or antibiotics if signs of secondary bacterial infection are present. The best prevention is vaccination by a veterinarian beginning at 6 weeks and repeated every 3-4 weeks until 20 weeks of age, then every 1-3 years as an adult.
