Canine Influenza: Signs & Symptoms to Watch For

Cold and flu season doesn’t just affect people — dogs can get sick, too. Canine influenza, or dog flu, is a contagious respiratory virus that spreads quickly anywhere dogs gather, from boarding facilities to dog parks. While most cases are mild, some can develop into serious respiratory illness.

How It Spreads

The virus spreads through airborne droplets from coughing, sneezing, or barking, as well as contaminated surfaces like water bowls, toys, and leashes. Because it’s highly contagious, even brief contact can be enough to transmit the virus.

Common Symptoms

Most dogs recover within two to three weeks, but secondary infections like pneumonia can occur in more severe cases.

• Persistent cough (wet or dry)
• Runny nose or watery eyes
• Fever
• Lethargy or decreased appetite
• Sneezing or nasal discharge

Prevention

• Keep your dog’s vaccines current — many veterinarians recommend the canine influenza vaccine for social dogs or those who frequent group settings.
• Avoid close contact with coughing or sick dogs.
• Wash hands and disinfect items after visiting public pet spaces.
  

If your dog starts coughing or showing flu-like symptoms, it’s best to contact your vet before visiting, as isolation may be necessary to prevent spread.
