Dog Breeds That Struggle in Hot and Humid Climates
Hot and humid weather can be challenging for many dogs, particularly those with short noses, thick coats, large body sizes, or existing breathing difficulties. In warm regions, including parts of South Asia, high temperatures and humidity can increase the risk of overheating, dehydration, and heatstroke.
Some dog breeds are more vulnerable to these conditions than others. Understanding their needs can help owners make responsible decisions about adoption, daily exercise, grooming, and home care.
This guide explains which dog breeds may struggle in hot and humid climates, why they are vulnerable, and how to keep them comfortable and safe.
At DogsLiveAsia, we share helpful information about dog breeds, responsible adoption, grooming, and everyday dog care to help owners make informed decisions about their pets.
Why Hot and Humid Weather Is Difficult for Dogs
Dogs do not cool themselves as efficiently as humans. They rely mainly on panting to release body heat, along with some heat loss through their paws. When the air is humid, moisture evaporates less effectively, making it harder for dogs to cool down.
Several factors can increase a dog’s risk of heat-related illness:
- Short noses: Flat-faced dogs may have difficulty breathing and regulating body temperature.
- Thick double coats: Dense fur can make heat management more challenging, although a coat also provides insulation.
- Large body size: Large dogs may generate and retain more body heat during physical activity.
- Age and health: Puppies, senior dogs, overweight dogs, and dogs with heart or respiratory conditions may be more vulnerable.
- Limited access to shade and water: Poor ventilation, direct sunlight, and hot outdoor surfaces increase the risk of overheating.
No breed is completely protected from heatstroke. Even dogs that are generally suited to warm climates can become seriously ill during extreme heat or strenuous exercise.
1. English Bulldog
English Bulldogs are among the breeds that require particular care in hot weather. Their short muzzles and compact airways can make breathing less efficient, especially when they are panting to cool themselves.
High humidity can further increase the difficulty of releasing body heat. Bulldogs may become distressed after relatively limited exercise in warm conditions.
Care tips:
- Keep the dog indoors in a cool, well-ventilated environment during hot periods.
- Schedule short walks during the coolest parts of the day.
- Avoid running, strenuous play, and long walks in the heat.
- Watch for unusually heavy panting, noisy breathing, weakness, or excessive drooling.
2. Pug
Pugs are small, affectionate companion dogs, but their flat faces can make them particularly susceptible to breathing problems and overheating.
Their shortened airways may prevent them from panting as effectively as dogs with longer muzzles. Hot, humid weather can therefore become dangerous, even when a Pug is not exercising heavily.
Care tips:
- Provide a cool indoor resting area.
- Keep outdoor activity brief and gentle during warm weather.
- Maintain a healthy body weight.
- Never force a Pug to continue walking if it appears tired or breathless.
Pugs may need more supervision than many other breeds during summer, especially when temperatures remain high throughout the day and night.
3. French Bulldog
French Bulldogs have short muzzles and compact airways, making them vulnerable to breathing difficulties in hot weather. Their limited ability to cool themselves through panting can increase the risk of heat exhaustion.
Humidity is an additional concern because it reduces the effectiveness of evaporative cooling.
Care tips:
- Prefer indoor exercise in a cool environment.
- Avoid walks during midday heat.
- Use a well-fitted harness rather than putting pressure on the neck.
- Seek veterinary advice if breathing becomes more difficult than usual.
French Bulldogs should never be left outdoors without access to a cool, shaded space and fresh drinking water.
4. Siberian Husky
Siberian Huskies developed in cold environments and have a dense double coat that helps insulate them against cold temperatures. They can adapt to some warmer conditions, but prolonged heat and humidity may make exercise and outdoor living difficult.
Their thick coat should not automatically be shaved. A healthy double coat provides insulation and protection from sunlight, and shaving it may interfere with its natural functions.
Care tips:
- Provide shade, ventilation, and a cool indoor area.
- Exercise early in the morning or later in the evening when conditions are safer.
- Brush regularly to remove loose undercoat and prevent matting.
- Never force a Husky to run or exercise in hot weather.
Huskies can live in warmer regions with careful management, but owners must be prepared to adjust their routines to the weather.
5. Chow Chow
Chow Chows have a dense coat, and their relatively short muzzle may also contribute to breathing and heat-management difficulties. These characteristics can make prolonged exposure to hot and humid weather particularly challenging.
Their heavy fur should be maintained through regular brushing rather than automatically shaved down.
Care tips:
- Keep the dog in a cool, shaded environment.
- Brush the coat regularly to prevent mats that interfere with normal coat function.
- Limit outdoor activity during hot periods.
- Monitor breathing, energy levels, and appetite during heat waves.
Chow Chows living in warm climates need attentive grooming and reliable access to comfortable indoor conditions.
6. Saint Bernard
Saint Bernards are large dogs with substantial body mass and a thick coat. These characteristics can make cooling down more difficult during strenuous activity in warm weather.
Their size also means that owners should pay attention to exercise intensity, hydration, and the temperature of outdoor surfaces.
Care tips:
- Provide a spacious, cool resting area.
- Keep exercise gentle during hot weather.
- Ensure fresh water is always available.
- Avoid leaving the dog in direct sunlight for extended periods.
Saint Bernards may need additional support during hot seasons, particularly in homes without adequate ventilation or cooling.
7. Newfoundland
Newfoundlands are large dogs with dense, water-resistant coats. Although they are known for their strength and swimming ability, these characteristics do not make them immune to heat stress.
Hot and humid weather can be especially challenging when a Newfoundland is active for extended periods or has no opportunity to rest in a cool environment.
Care tips:
- Keep exercise moderate during warm weather.
- Brush the coat regularly and maintain good skin health.
- Provide shade and a cool resting area.
- Supervise activity carefully and allow frequent breaks.
Access to water for swimming is not a substitute for proper cooling, and dogs should not be forced to swim when they are tired or overheated.
8. Pekingese
Pekingese dogs have short muzzles and long coats. Their facial structure can make breathing less efficient, while their coat requires regular maintenance.
These characteristics may increase the risk of overheating during warm, humid weather.
Care tips:
- Keep walks short during hot periods.
- Maintain a clean, well-groomed coat.
- Avoid excessive exercise.
- Watch for heavy panting, noisy breathing, and unusual tiredness.
Owners should discuss breathing concerns with a veterinarian rather than assuming that persistent snoring or noisy breathing is always normal.
Are Long-Haired Dogs Always Unsuitable for Hot Climates?
No. Coat length alone does not determine whether a dog can live comfortably in a warm region. Some long-haired dogs can adapt to warmer conditions, while some short-haired dogs are highly vulnerable because of their facial structure or medical conditions.
A dog’s risk depends on several factors, including:
- Coat type and density
- Muzzle length and airway health
- Body size and fitness
- Age and underlying medical conditions
- Temperature, humidity, and access to cooling
- Exercise intensity and duration
Double coats can provide insulation as well as protection from sunlight. For this reason, shaving a double-coated dog is not a universal solution to heat management. Regular brushing, appropriate shelter, and veterinary grooming advice are generally more suitable approaches.
How to Keep Dogs Safe in Hot and Humid Weather
Responsible care can reduce heat-related risks, even for breeds that are more sensitive to warm conditions.
Provide Fresh Water
Keep clean drinking water available throughout the day. Refill bowls regularly and take water with you when travelling with your dog.
Create a Cool Resting Area
Allow dogs to rest indoors in a well-ventilated room. Air conditioning can be particularly helpful during periods of extreme heat. Shade and fans may help, but a fan alone may not adequately protect a dog in very hot, humid conditions.
Walk During Cooler Hours
Schedule walks early in the morning or later in the evening when temperatures and ground surfaces are cooler. Adjust the length and intensity of exercise according to the dog’s breed, health, and behaviour.
Never Leave Dogs in Parked Cars
A parked vehicle can become dangerously hot very quickly, even if the windows are slightly open or the weather initially feels mild. Never leave a dog unattended in a parked car.
Maintain a Healthy Weight
Excess weight can make heat management and exercise more difficult. Provide an appropriate diet and activity routine based on veterinary advice.
Recognize Warning Signs of Heatstroke
Signs of heat-related illness can include excessive panting, heavy drooling, weakness, vomiting, confusion, poor coordination, and collapse.
If heatstroke is suspected, move the dog to a cooler area, begin cooling it with cool—not ice-cold—water, and contact a veterinarian immediately. Do not delay veterinary care while waiting for the dog to improve.
Choosing a Dog Breed for a Hot Climate
If you live in a region with long, hot summers and high humidity, consider a dog’s individual health and cooling needs before adoption.
Rather than selecting a breed based only on appearance, size, or popularity, ask whether you can provide suitable indoor conditions, safe exercise, regular veterinary care, and protection from extreme weather.
Some dogs may be better adapted to warm conditions, but no breed should be considered completely heatproof. A local mixed-breed dog may also be a good companion, depending on its individual characteristics, health, and temperament.
Before adopting, discuss the dog’s likely adult size, coat, respiratory health, and exercise needs with a veterinarian or responsible animal-welfare organization.
Frequently Asked Questions
Which dog breeds struggle most in hot and humid climates?
Flat-faced breeds such as English Bulldogs, Pugs, and French Bulldogs are particularly vulnerable because their shortened airways can make breathing and cooling difficult. Thick-coated breeds, including Siberian Huskies, Chow Chows, Saint Bernards, and Newfoundlands, may also require careful heat management.
Can Huskies live in hot countries?
Yes, some Huskies can live in hot countries if their owners provide suitable indoor cooling, fresh water, shade, and carefully timed exercise. However, prolonged heat can be difficult for them, and they should never be forced to exercise in unsafe conditions.
Should I shave my dog’s fur during summer?
Not necessarily. Shaving a double-coated dog can interfere with the coat’s protective and insulating functions. Regular brushing and professional veterinary or grooming advice are better starting points. Severe matting may require specific treatment.
What is the safest time to walk a dog in hot weather?
Early morning and later evening are generally preferable to midday, but the safest time depends on local temperature, humidity, and ground conditions. Shorten or skip walks when conditions are unsafe.
How can I tell if my dog is overheating?
Warning signs include excessive panting, heavy drooling, weakness, vomiting, confusion, and collapse. Suspected heatstroke is an emergency that requires immediate cooling measures and urgent veterinary attention.
Conclusion
Hot and humid climates can pose serious challenges for certain dog breeds, particularly flat-faced dogs and breeds with dense coats or large body sizes. English Bulldogs, Pugs, French Bulldogs, Huskies, Chow Chows, Saint Bernards, Newfoundlands, and Pekingese may need additional protection during warm weather.
However, responsible ownership is about more than breed selection. Providing fresh water, appropriate exercise, a cool living environment, regular grooming, and prompt veterinary care can help dogs remain safer and more comfortable.
Before adopting a dog, consider the local climate and your ability to meet its long-term needs. Every dog deserves a safe home where its health, comfort, and well-being come first.
