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.
Case Study: Lilly’s Story

Lilly Recovering from her BOAS surgery.
Lilly, a sassy flat-nosed dog with a big personality, had been struggling with noisy breathing, frequent coughing, and difficulty keeping up on walks. Her breathing issues were so uncomfortable that she had to go on steroid medication just to help her breathe more easily—but this wasn’t a long-term solution.
After discussing the options with our veterinary team, Lilly underwent BOAS (Brachycephalic Obstructive Airway Syndrome) surgery. The procedure made a world of difference. Now, Lilly breathes more freely, is far more comfortable, and can enjoy her walks more. Her transformation has been a joy to see!
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.
