My Pet Folio

Kennel cough is a highly contagious respiratory infection common in dogs who have been in close contact with other dogs (e.g., at boarding kennels, dog parks, or training classes). It is caused by various viruses and bacteria and usually results in a self-limiting but persistent cough.

Symptoms:

A strong, persistent, "honking" cough
Retching or gagging after coughing, sometimes producing white foam
Watery nasal discharge
Mild lethargy or fever (in some cases)
Generally, the dog will otherwise appear well and have a normal appetite

Home Care:

Isolate your dog from other dogs to prevent spread.
Use a harness instead of a collar for walks to avoid pressure on the trachea.
Keep your dog in a well-ventilated area. Using a humidifier can help soothe the airways.
Encourage rest and avoid strenuous activity.
Contact your veterinarian for diagnosis and potential treatment (e.g., cough suppressants or antibiotics if a bacterial infection is suspected).

Important Warning

While typically mild, kennel cough can sometimes progress to pneumonia, especially in puppies, senior dogs, or those with compromised immune systems. Seek veterinary care if your dog shows signs of lethargy, loss of appetite, fever, or difficulty breathing.
