Rising temperatures in the summer directly affect not only people but also dogs. However, not every dog is affected in the same way. Some breeds are much more sensitive to hot weather due to their body structure, coat characteristics, or respiratory systems. In such dogs, heatstroke, fainting due to heat stress, breathing difficulties, and even sudden death may occur.

In this article, we take a detailed look at the dog breeds that are more sensitive to hot weather, the reasons for this, and the precautions owners should take. If you want to keep your companion safe in hot weather, this information will guide you.

1. Why Are Some Breeds More Sensitive to Heat?
Sensitivity to heat depends on the dog’s physical traits, coat thickness or color, nasal and respiratory structure, weight, and overall health. The main factors include:

• Short nasal structure (brachycephalic breeds)

• Thick and double coats

• Excess weight (obesity)

• Dark-colored coats (absorb more heat)

• Puppies, elderly, or sick dogs

2. Dog Breeds at Higher Risk in Hot Weather
Here are the main breeds at high risk in summer and the reasons:

a. French Bulldog

• Brachycephalic (very short nose)

• Narrow airways make breathing difficult

• Poor heat regulation, very prone to heatstroke

b. English Bulldog

• Short nose and excessive skin folds reduce heat tolerance

• Tongue often hangs out, very limited ability to sweat

c. Pug

• Small but extremely short-nosed

• Protruding eyes prone to infections in hot, dusty air

• Easily stressed in hot conditions

d. Shih Tzu

• Thick double coat

• Short, flat face makes breathing harder in summer

• Without a summer trim, severe heat stress can occur

e. Chow Chow

• One of the thickest coats among dogs

• Dislikes heat, pants heavily even in shade

• Extra body fat raises body temperature

f. Saint Bernard

• Large body and dense coat make them intolerant of heat

• Adapted for cold climates

• Overheats quickly even when inactive

g. Siberian Husky

• Bred for northern climates

• Thick coat makes them vulnerable in summer

• Tires easily and risks heatstroke during exercise

h. Pekingese

• Despite small size, short nose and thick coat are major disadvantages

• Higher mortality risk in older Pekingese during hot weather

i. Boxer

• Energetic but short-nosed, overheats easily in summer

• Body temperature rises quickly during exercise

3. Are There Breeds More Tolerant of Heat?
Yes, some breeds adapt better to hot weather. For example:

• Basenji: Short-haired, African origin

• Ibizan Hound: Lean body and short coat help tolerate heat

• Mexican Hairless (Xoloitzcuintli): Hairless, naturally suited to hot climates

Still, the safest way for every dog is to ensure access to cool areas, fresh water, and shade.

4. Precautions for At-Risk Breeds in Summer

• Walk during early morning or late evening hours

• Provide a cool area at home with a fan or air conditioning

• Maintain coat care; consider a summer trim (with vet approval)

• Provide plenty of water, and use frozen treats if necessary

• Reduce exercise during summer months

• Never leave dogs in cars

• Ensure your vacation accommodation offers cooling options

---

5. Warning Signs of Heat Danger

• Rapid, shallow breathing

• Excessive drooling

• Weakness or fainting

• Increased heart rate

• Vomiting or diarrhea

• Disorientation or confusion

If even one of these symptoms appears, immediate cooling measures should be taken, and a veterinarian should be contacted right away.

Conclusion: Care Should Be Based on Needs, Not Just Breed

In summer, every dog can be at risk, but some breeds are naturally more vulnerable. This is why owners must understand their dog’s physical traits, provide care tailored to their specific needs, and avoid excessive exercise in hot weather.

Remember: your furry friend’s health is directly linked to your knowledge and attention. Take the effects of heat seriously and ensure your dog enjoys the summer safely and comfortably.
