Not every dog can handle high temperatures—and that matters in hot regions. Certain breeds are naturally better adapted for warm weather, with body structures, coat types, and traits that help them stay cool. Selecting a dog suited to your climate helps ensure comfort, health, and safety—whether looking for a small companion, a large family protector, or an active working partner.

Physical Traits That Help Dogs Stay Cool

Short coats allow body heat to escape more easily. Sleek coats, like those on Greyhounds or Dalmatians, promote airflow and reduce heat retention.

Large ears act as natural radiators. Blood vessels in the ears release heat into the air, a trait seen in breeds such as the Ibizan Hound and Saluki.

Lean body types reduce insulation. Breeds like the Italian Greyhound and Whippet have low body fat and thin skin, allowing them to cool more quickly.

Why Face Shape Matters

Dogs with long muzzles cool incoming air more efficiently, reducing heat stress. Dobermans and Weimaraners breathe more effectively in high temperatures than flat-faced breeds.

Short-nosed (brachycephalic) dogs—such as Bulldogs and Pugs—are prone to overheating because their restricted airways make panting less effective.

Small Dog Breeds For Hot Weather

Chihuahua

Originating in Mexico, Chihuahuas weigh 2–6 pounds and have short coats that release heat quickly. Large ears aid cooling. Smooth-coated varieties are especially suited to warm weather.

Italian Greyhound

This sleek, low-fat breed has a short coat and an athletic build. Agile and quick, Italian Greyhounds cool off rapidly after exercise. Light skin requires sun protection during peak hours.

Xoloitzcuintli

A hairless breed from Mexico, the Xolo dissipates heat efficiently. Long muzzles and lean bodies further aid cooling, but skin protection from sunburn is essential.

Key traits for small heat-tolerant dogs: Short or absent coats, long muzzles, large ears, lean frames, and lower activity during peak heat. Learn more about what small dog is the best fit for you with help from Puppy Dreams.

Large Dogs Built for Warm Climates

Great Dane

Despite their size, Great Danes have short coats and a calm demeanor, helping them stay cool. However, they require ample water due to their large body mass.

Vizsla & Weimaraner

Both breeds were developed for warm-weather hunting. Thin coats, light coloring, and lean builds help maintain a safe body temperature.

Doberman Pinscher

With sleek coats and athletic frames, Dobermans adapt well to heat when given shade, water, and breaks from activity.

Hot-weather tips for large dogs: Exercise in the morning or evening, ensure frequent hydration, and provide shaded rest areas.

Medium Breeds for Hot Regions

Australian Cattle Dog

Bred to work under the Australian sun, these dogs have short double coats for both sun protection and ventilation.

Basenji

From Africa, Basenjis have short coats, large ears, and long muzzles that support efficient cooling.

Ibizan Hound

Light-colored coats, long legs, and large ears make Ibizan Hounds well adapted to warm conditions.

Family-Friendly Breeds for Sunny Climates

Dalmatian

Thin coats, long noses, and active temperaments make Dalmatians a good match for warm regions, with rest breaks during peak sun.

Greyhound & Whippet

Both breeds have short coats, lean bodies, and gentle temperaments, making them excellent family companions in warmer climates.

Breeds to Avoid in Hot Climates

• Dogs with flat faces: Pugs, Bulldogs, and Boxers struggle to pant effectively, making them vulnerable to heatstroke.
• Heavy-coated breeds: Huskies, Chow Chows, and Pomeranians trap heat and overheat quickly in hot weather.
• Warning signs of heat distress: Heavy panting, drooling, sluggish movement, vomiting, or collapse. Immediate cooling and veterinary care are essential.

Hypoallergenic Dogs That Do Well in Heat

• Chinese Crested: Hairless variety dissipates heat well, but requires sun protection.
• American Hairless Terrier: Low-maintenance coat, but needs UV protection
• Toy & Miniature Poodles: Low-shed coats; adapt well indoors during high heat.
• Xoloitzcuintli: Both coated and hairless varieties handle heat effectively.

​Hot-Weather Safety Tips for All Dogs

• Provide constant shade and fresh water.
• Avoid midday walks; opt for early morning or evening.
• Test pavement temperature before walking.
• Use cooling vests, mats, or dog-safe sunscreen as needed.
• Maintain regular grooming to improve airflow without shaving double-coated breeds.
