Brachycephalic dogs face extreme risk from overheating due to compromised respiratory anatomy. Advanced understanding of thermal physiology in these breeds enables better welfare management.
Brachycephalic dogs experience a thermal welfare emergency risk in conditions that normal dogs tolerate comfortably. Their compromised anatomy means they cannot dissipate heat efficiently, creating dangerous overheating from minimal exercise in moderate temperatures. Owners of brachycephalic dogs must apply dramatically more conservative management of exercise and heat exposure. BOAS surgery that widens airways significantly improves thermal tolerance and welfare.
