Symptoms of Kennel Cough in Dogs

Kennel cough is an upper respiratory disease thought to be caused primarily by the bacterium Bordetella bronchiseptica and other bacteria and viral agents. Named for its prevalence at boarding kennels, the disease spreads quickly among dogs. Also known as tracheobronchitis, kennel cough affects dogs of all ages.

  1. Exposure

    • Contact with dogs in boarding kennels, animal hospitals and dog parks may expose your dog to the highly contagious disease. The virus develops within two to 14 days. In most cases, a dog does not seem sick.

    Cough

    • A cough may alert you to your dog's illness. The primary symptom is a dry hacking cough, described as a honking sound, which lasts about 10 days.

    Discharge

    • Nasal discharge or a runny nose is typical. Your dog also may cough up foamy mucus to clear his airways.

    Lethargy

    • If your dog loses interest in eating, is lethargic or has a fever, the infection is more severe and could turn into pneumonia. Your veterinarian will test for specific viral or other organisms.

    Treatment

    • Mild cases may benefit from antibiotics, bronchodilators to open airways or cough suppressants. Serious cases require antibiotics and veterinary care. Severe infections and complications can cause death.
