As summer temperatures rise, most dog owners become more aware of the dangers of heatstroke. But for brachycephalic (short-muzzled) breeds like pugs, bulldogs, boxers, shih tzus, and Boston terriers, the heat poses an even greater risk. Flat-faced dogs suffer heat-related health emergencies—and we want to help you prevent that from happening.
Here’s why these lovable snub-nosed pups are at higher risk, and how you can keep them cool and safe all summer long.
Why Flat Faces Make It Hard to Stay Cool
Dogs don’t sweat like humans do—they cool off mainly by panting. But brachycephalic breeds have shortened skulls, compact airways, and narrowed nostrils, which means they pant inefficiently. When it’s hot, their bodies can’t cool down fast enough, and their core temperature can rise to dangerous levels in just minutes.
Brachycephalic breeds are more prone to a condition called Brachycephalic Obstructive Airway Syndrome (BOAS), which makes it even harder to breathe normally, especially during exercise or stress. Add heat and humidity, and you’ve got a recipe for a life-threatening emergency.
Heatstroke Hits Hard and Fast
Dogs suffering from heatstroke can experience symptoms such as:
Heavy, labored panting
Bright red or purple gums
Vomiting or diarrhea
Disorientation or staggering
Collapse or loss of consciousness
For brachycephalic dogs, these signs can come on rapidly—even during a short walk in the heat or a car ride without adequate airflow. Once a dog’s internal temperature reaches above 104°F, organ damage can begin, and immediate veterinary attention is needed.
Tips to Protect Your Brachy Pup This Summer
Avoid Midday Walks: Walk your dog early in the morning or after sunset when temperatures are lower. Stick to shaded areas and avoid hot pavement that can burn paws.
Provide Constant Access to Cool Water: Hydration is crucial. Keep bowls of fresh, cool water available at all times, and consider using a dog-friendly water fountain or portable bowl when outside.
Never Leave Them in a Car: Not even for a few minutes. Temperatures inside vehicles can spike dangerously in seconds—even with windows cracked.
Keep Indoor Temperatures Comfortable: Use fans, AC, or cooling mats inside your home. Some dogs even benefit from dog-safe frozen treats or damp cooling towels.
Know When to Call the Vet: If your brachycephalic dog seems unusually tired, refuses to eat, or struggles to breathe, don’t wait.
Long-Term Care: Consider a BOAS Evaluation
Some brachycephalic dogs benefit from surgical correction of anatomical issues like elongated soft palates or stenotic (narrow) nostrils.
We love our smooshy-faced friends just as much as you do—but summer isn’t always kind to them. Prevention is key. By staying alert, keeping your dog cool, and knowing the signs of trouble, you can help ensure your furry friend enjoys a safe, happy summer.
