Your Dog Might Be at Risk—12 Breeds That Overheat Easily

Many dog breeds have a natural ability to adapt to different climates and weather conditions. However, some breeds may struggle to cope with extreme temperatures, particularly those that are prone to respiratory problems or have thick fur coats.

Dogs regulate their body temperature differently from humans, and they are more susceptible to heatstroke and dehydration. It is important to be aware of your dog’s needs, especially during the summer months. By knowing which breeds are more likely to struggle in the heat, dog owners can take the necessary precautions to keep their pet safe and healthy.

1) Bulldog

Bulldogs are a popular breed known for their wrinkly faces and friendly demeanor. However, they are also one of the breeds that struggle the most in hot weather.

Bulldogs have a short snout, which makes it difficult for them to cool down by panting. This can lead to overheating and heatstroke, especially if they are exposed to high temperatures for a prolonged period. It’s important to keep Bulldogs cool and hydrated during hot weather. They should have access to plenty of water and shade, and should not be left outside for extended periods of time.

Owners should also avoid exercising Bulldogs during the hottest parts of the day and should watch for signs of overheating, such as excessive panting, drooling, and lethargy.

2) Pug

Pugs are a popular breed known for their wrinkly faces and cute personalities. However, these adorable dogs are not well-suited for hot weather. Due to their short snouts and compact size, Pugs struggle to regulate their body temperature in high temperatures and humid conditions.

Temperatures above 80°F can cause discomfort for Pugs, and temperatures over 90°F pose a serious risk to their health. Signs of heatstroke in Pugs include excessive panting, lethargy, and vomiting.

3) French Bulldog

French Bulldogs are a popular breed, but they also struggle in the heat. They have a short snout, which makes it difficult for them to regulate their body temperature. As a result, they are more prone to heat exhaustion and heatstroke.

If you own a French Bulldog, it is important to be aware of the signs of heat exhaustion and heatstroke. These include excessive panting, drooling, lethargy, and vomiting. If your French Bulldog shows any of these symptoms, it is important to seek veterinary care immediately.

4) Boxer

Boxers are a medium-sized breed that is known for their loyalty and affectionate nature. They have short, smooth coats that come in a variety of colors, including fawn, brindle, and white. While they are generally a healthy breed, Boxers are prone to overheating due to their short snouts and compact build.

Boxers are not well-suited to hot and humid climates, and they can quickly become overheated if they are not provided with adequate shade and water. They are also prone to sunburn, so it’s important to keep them out of direct sunlight during the hottest parts of the day.

5) Shih Tzu

Shih Tzus are a small breed with long, thick coats that can make it difficult for them to regulate their body temperature in hot weather. They are prone to overheating and heatstroke, which can be life-threatening.

To keep Shih Tzus cool in hot weather, provide plenty of shade and cool water. Avoid exercising them during the hottest parts of the day.

6) Chow Chow

Chow Chows are one of the dog breeds that really struggle in the heat. According to a study, they are 17 times more likely to suffer from heatstroke than the average dog. This is because they have a thick double coat that was originally bred to keep them warm in cold weather.

Chow Chows are also brachycephalic, which means they have a flat face and a short snout. This can make it difficult for them to breathe, especially in hot and humid weather. Additionally, they have a high body fat percentage, which makes it harder for them to regulate their body temperature.

7) Pekingese

The Pekingese is a small dog breed that was originally bred as a companion dog for Chinese royalty. They have a distinctive appearance with long, flowing hair and a flat, wrinkled face.

Pekingese are not built for strenuous exercise and can quickly overheat in hot weather. They are also prone to respiratory problems, which can be exacerbated by high temperatures. Regular grooming can also help keep their coat from becoming too thick and matted, which can trap heat and make them uncomfortable.

8) Boston Terrier

Boston Terriers, also known as “The American Gentleman,” are a popular breed known for their affectionate and lively personalities. However, they are not the best-suited breed for hot weather due to their short snouts and compact size.

In hot weather, Boston Terriers are prone to heatstroke and other heat-related illnesses. They should be kept in air-conditioned environments and given plenty of water and shade when outside.

9) Cavalier King Charles Spaniel

Cavalier King Charles Spaniels are a loving and gentle breed that make great companions. They are well-suited to a variety of family structures and living situations but they are not the best dog breed for hot climates.

Cavaliers have a hard time dealing with extreme heat or humidity. They are sensitive to weather conditions and can get sick if they’re exposed to high temperatures for too long. It’s important to keep them in a cool environment and give them plenty of water to drink.

10) English Setter

English Setters are a medium to large-sized dog breed that originated in England. They have a sweet, charming, and fun personality, making them great family pets. English Setters have long, silky hair that requires regular grooming to prevent matting.

They are prone to heat exhaustion due to their long hair and the fact that they were bred to hunt in cooler climates. Therefore, it is important to keep them in a cool and shaded area during hot weather. While English Setters are active dogs, they are not well-suited for hot climates. They prefer cooler temperatures and may struggle in the heat.

11) Basset Hound

Basset Hounds are known for their droopy ears, soulful eyes, and gentle disposition. They are a lovable breed that makes great family pets. However, their long ears and short legs make them prone to overheating in hot weather.

Basset Hounds have a thick coat that provides insulation in colder weather, but can be a burden in the heat. They are also susceptible to skin infections and other heat-related illnesses. It is important to keep them cool and hydrated during hot weather.

12) Saint Bernard
