If you’re a pooch parent, your ears likely prick up at the mention of canine kennel cough. But what is it, and how can you best protect your dog?

Kennel cough isn’t just one disease, it’s a group of viral and bacterial diseases collectively known as canine infectious respiratory disease complex.

The classic sign of kennel cough is a persistent honking cough. But depending on the infection involved and the strength of your dog’s immune system, signs can range from lethargy and loss of appetite to pneumonia and other severe illnesses.

Because kennel cough is highly contagious, vaccination can lower the risk of infection and reduce the severity of illness. During outbreaks, it’s also important to limit your pooch’s contact with other dogs.
