Why Flat-Faced Dogs Struggle More in Summer Heat
Summer can be tough on all dogs, but it can be especially dangerous for flat-faced breeds like Bulldogs, French Bulldogs, Pugs, Boston Terriers, Shih Tzus, Boxers, and Pekingese.
These breeds are known as brachycephalic dogs, meaning they have shortened noses and airways. While their adorable faces are part of their charm, their anatomy can make it harder for them to breathe and cool themselves down—especially during hot, humid weather.
Why Are They More at Risk?
Unlike people, dogs don't sweat to cool off. They rely on panting to release body heat. Because brachycephalic dogs often have narrowed airways, panting requires more effort and may not cool them as effectively.
Heat, humidity, excitement, exercise, and excess weight can all make breathing even more difficult, increasing the risk of overheating.
Signs of Heat Stress
Watch for:
- Heavy or nonstop panting
- Noisy, strained breathing
- Excessive drooling
- Weakness or slowing down
- Bright red, pale, gray, or blue gums
- Vomiting or diarrhea
- Collapse or severe breathing difficulty
If you notice any of these signs, move your dog to a cool area immediately and contact a veterinarian.
Summer Safety Tips
Exercise During Cooler Hours
Walk your dog early in the morning or later in the evening when temperatures are lower. Keep walks shorter than usual and let your dog set the pace.
Provide Plenty of Water and Shade
Always have fresh water available and make sure your dog has access to shade or air conditioning.
Be Careful With Hot Surfaces
Pavement can stay hot long after the sun goes down. Test the surface with your hand before walking your dog.
Never Leave Your Dog in a Parked Car
Temperatures inside a vehicle can become dangerous within minutes, even with windows cracked.
Maintain a Healthy Weight
Extra weight puts additional strain on the airway and can make breathing more difficult in warm weather.
When Is It an Emergency?
Seek immediate veterinary care if your dog is struggling to breathe, collapses, has vomiting or diarrhea, develops abnormal gum color, or seems unable to cool down.
Move your dog to a cool area, offer small amounts of water if they're alert, and begin cooling them with cool (not ice-cold) water while contacting a veterinarian.
Helping Your Dog Enjoy Summer Safely
Flat-faced dogs can still enjoy summer activities, but they often need extra precautions. Planning outdoor time during cooler parts of the day, keeping activity levels reasonable, and closely monitoring your dog's breathing can help prevent heat-related emergencies.
If you have concerns about your dog's breathing, exercise tolerance, or heat sensitivity, schedule an appointment with your veterinarian.
