Breeds like Siberian Huskies, Alaskan Malamutes, and Saint Bernards have adapted to harsh, cold climates over centuries. These adaptations give them a better natural defense against cold weather conditions and frostbite, but it’s important to understand why and how this works. Many cold-resistant breeds have a double coat. The undercoat is dense and woolly, acting as an insulator to retain body heat. The outer coat is longer and water-resistant, protecting the dog from snow and ice. This dual-layer system provides significant warmth and protection compared to the single-layer coats of other breeds. Body Fat and Muscle Mass: These breeds often have higher body fat and muscle mass, providing additional insulation and warmth. Physical Structure: Dog breeds built for cold climates typically have a more compact body structure, with shorter ears and tails, reducing the surface area exposed to cold and decreasing the risk of frostbite. Their paws are also specially adapted, with a more significant fat pad and often webbed toes, which provide better traction and insulation against the snow and ice.

Dogs don't freeze because the arrangement of blood vessels beneath the animals’ skin keeps the temperature just right. The arrangement helps the animal hold on to body heat, which might otherwise be easily lost through their hairless paws. Dogs can fetch and roll over in the snow without fear of frostbite, thanks to the arrangement of blood vessels in their paws. The scientists discovered that veins surround the arteries that deliver warm blood to dog paws. The two kinds of blood vessels are so close together that they exchange heat: The warm arteries heat up the cooler veins. As a result, the temperature in the paw stays balanced. Warm blood reaches the pad’s surface to keep frostbite away, but without letting the animal lose too much body heat. Scientists call this kind of system a counter-current heat exchanger.

It turns out that the paws of dogs have a unique arrangement of blood vessels and fat that help keep the area warm. This may explain why many dogs are able to walk on cold surfaces better than we humans can barefoot. However, this trait varies from dog to dog, and certain breeds may be more or less adaptable to walking on cold ground. Some dogs enjoy cold weather, and many breeds are more tolerant of the cold than others, such as Siberian huskies and Alaskan Malamutes. But loving the cold doesn't mean they can tolerate frigid temperatures, so it's important to prevent prolonged exposure to cold. The direct contact with cold surfaces literally freezes the tissues and causes damage, but the unique arrangement of blood vessels and fat in their paws helps to minimize this risk. Fortunately, frostbite is not especially common in dogs.

Dogs have tiny ‘heat exchangers’ in their feet that allow the cold venous blood returning to the heart to be rewarmed by the arterial blood traveling to the toes. This keeps the core body temperature protected while allowing the toes not to freeze. When our feet get cold, our body constricts our feet’s blood vessels to slow blood flow to protect our core body temperature. Low blood flow can mean not just discomfort, but possible frostbite. Researchers in Japan have studied dogs’ feet circulation patterns and found an interesting difference from humans.

Obviously, cold-weather breeds such as the Siberian Husky and the Alaskan Malamute are less prone to this condition.
Breed type certainly does play a factor in how susceptible a dog is to getting frostbite.
Small dogs, shorthaired dogs, puppies, and senior dogs are at the biggest risk of frostbite.
A warm dog winter coat, sweater, and boots will help minimize the risk, especially for short-coated breeds or older, more fragile animals.
Make sure your dog is dry before taking them out for a walk.
If a dog is wet or damp, these areas are more vulnerable to frostbite.
Keep winter walks short when possible.
A dog can start developing frostbite in as little as 30 minutes.
