Canine influenza, or “dog flu,” is a highly contagious respiratory disease affecting dogs across the U.S. It’s caused by specific strains of influenza virus — H3N8 and H3N2 — and spreads easily in areas where dogs gather, such as parks, kennels and grooming facilities. Dogs infected with the flu can exhibit symptoms similar to a cold, including coughing, sneezing, fever, lethargy and loss of appetite. In some cases, it can progress to pneumonia, which can be life-threatening, especially in puppies, older dogs or those with underlying health conditions.
To protect your dog, vaccination is one of the best steps. Although it doesn’t prevent infection entirely, it reduces the severity of symptoms and decreases the chance of transmission. Many veterinarians recommend vaccination, especially for dogs frequently in close contact with others.
While flu in dogs is not transmitted to humans (or vice versa), protect your pup with good hygiene by washing your hands and changing clothes if you’ve been around other dogs, especially if a local outbreak has been reported. Avoid taking your dog to crowded areas during flu season, and keep your dog at home if they exhibit any symptoms of illness. These precautions can significantly lower the risk of infection and help keep your furry friend healthy year-round.
