Canine Parainfluenza is a highly contagious viral infection that affects dogs, primarily impacting their respiratory system. It is one of the key contributors to kennel cough, a common condition in dogs, especially those in crowded environments like shelters or boarding facilities. Symptoms often include a dry cough, nasal discharge, and fever. The virus is spread through respiratory secretions, making close contact with infected dogs a significant risk factor. Vaccination is available and recommended to help protect dogs from this virus. While most dogs recover without severe complications, some may develop more serious respiratory issues, especially if they have underlying health problems.
