Flat-Faced Breeds and Exercise: Walking Pugs, Bulldogs, and More

Pugs, French Bulldogs, English Bulldogs, Boston Terriers, Shih Tzus, and Boxers share a trait called brachycephaly— a shortened skull that gives them their adorable flat faces. It also means their airways are compromised, making exercise riskier.

Why They Overheat Faster

Dogs cool themselves by panting — moving air rapidly over the moist surfaces of their tongue and airways. Brachycephalic dogs have narrowed nostrils, elongated soft palates, and smaller tracheas, which means they can't move air as efficiently. They overheat at temperatures that would be comfortable for other breeds.

Safe Exercise Guidelines

• Keep walks short: 15-25 minutes is often plenty
• Avoid heat: If it's above 75°F, keep walks under 15 minutes or skip them
• No intense exercise: Running, fetch on hot days, and dog parks with high-energy chasers are risky
• Use a harness, not a collar: Collars restrict an already-compromised airway
• Bring water always: Even on short walks in mild weather

Warning Sounds

Learn to distinguish your flat-faced dog's normal breathing from distressed breathing:

• Normal: Soft snoring, occasional snorting
• Concerning: Loud wheezing, gagging, retching, or blue-tinged tongue
• Emergency: Inability to catch breath, collapse, blue/purple gums

Best Walk Times for Flat-Faced Breeds

Stick to early morning or late eveningin warm months. In winter, midday walks are fine since cold air is actually easier for brachycephalic dogs to breathe (but watch for very cold temps below 30°F). Spring and fall are their golden seasons.
