Kennel Cough

By Kay Hisano | Dated February 17, 2026

We have recently seen an increase in kennel cough cases at our clinic and wanted to share important information with owners.

What is Kennel Cough?

Kennel cough, or canine infectious respiratory disease, is a highly contagious infection of the upper airways. It is commonly caused by Bordetella bronchiseptica bacteria and/or parainfluenza virus, and spreads quickly in places where dogs gather, such as boarding facilities, dog parks, daycare, grooming salons, and training classes.

Signs to Watch For

• Persistent, dry, hacking cough (often described as honking).

• Can sometimes even sound like your dog has something stuck in their throat and trying to clear it

• Retching or foamy vomit after coughing

• Mild lethargy or reduced appetite

Many dogs otherwise appear bright and alert despite the cough.

Treatment & Care

Most healthy adult dogs recover within 1–3 weeks with rest and supportive care, while some dogs may require medications such as cough suppressants or antibiotics. Puppies, older dogs, and those with underlying health conditions are at higher risk of complications like pneumonia.

Vaccination

Vaccination can reduce the severity and spread of kennel cough. The yearly vaccination we provide here at Gordon Vet covers protection against kennel cough. However, this does not guarantee your dog will not get it, but it helps reduce the risk of severe illness.

Preventing Spread

If your dog is coughing, keep them away from other dogs and indoors to help protect the wider dog community.
