Canine Influenza, also known as dog flu, is a contagious respiratory infection caused by specific strains of the influenza virus. It primarily affects dogs, leading to symptoms such as coughing, sneezing, nasal discharge, and fever. The virus spreads through respiratory droplets and contaminated surfaces, making it easy for dogs to contract it in places like dog parks or boarding facilities. Vaccines are available to help protect dogs from Canine Influenza, but not all dogs are vaccinated. Most dogs recover within a few weeks, although some may develop more severe symptoms or complications. Pet owners should consult their veterinarians for guidance on prevention and treatment options.
