Brachycephalic Obstructive Airway Syndrome

by | Jun 17, 2025

Keeping Your Brachycephalic Dog Safe This Summer

As summer approaches and temperatures rise, it’s especially important for owners of brachycephalic (flat-faced) dogs—like Pugs, Bulldogs, Shih Tzus, and French Bulldogs—to be aware of a condition called Brachycephalic Obstructive Airway Syndrome (BOAS).

These breeds are loved for their adorable looks and charming personalities, but their short snouts and compact airways can make breathing a real challenge—particularly in warm weather. BOAS refers to a group of anatomical issues including narrowed nostrils, an elongated soft palate, and other airway abnormalities that can cause labored breathing, snoring, gagging, and exercise intolerance.

Why Summer Makes It Worse

Heat and humidity can seriously strain a brachycephalic dog’s already compromised respiratory system. Because dogs regulate their body temperature through panting, dogs with BOAS often struggle to cool down efficiently, putting them at higher risk for heat exhaustion or even heatstroke.

How We Can Help

If your dog shows signs of breathing difficulty or struggles in the heat, we recommend booking a consultation with one of our vets. In some cases, corrective surgery can significantly improve your dog’s ability to breathe and enjoy life more comfortably. Procedures can involve widening the nostrils or shortening the soft palate to allow better airflow.

In the meantime, keep your brachycephalic dog cool, avoid strenuous walks during the heat of the day, and always have fresh water available.

We’re here to help you keep your furry friend happy and healthy all year round—especially during the hot months. If you have concerns or would like to discuss whether surgery may be beneficial for your dog, don’t hesitate to reach out.
