Sled dogs, also known as mushing dogs, are a type of working dog that pulls sleds. The most common breeds used for this purpose are northern dog breeds such as Siberian Huskies and Alaskan Malamutes, known for their ability to withstand harsh climates and terrains. The dietary requirements of sled dogs are unique, as they need to maintain weight and energy for endurance racing. Their diets are typically high in protein and fat, with chicken and salmon being popular choices. During extremely cold weather, their diets may be supplemented with lard. While sled dogs do not require special food, their diets need to be carefully monitored to ensure they receive adequate nutrition to support their active lifestyles.

What You'll Learn
Sled dogs' high-calorie, high-protein, and high-fat diets
Sled dogs have unique dietary requirements to maintain weight and provide energy for exercise. They can consume up to 10,000 calories a day and require a nutrient-dense, high-fat, high-protein diet. Their energy requirements are substantially higher during racing than when at rest, by 2-5 times.
Sled dogs are fed a high-performance dry dog food called kibble. This is often mixed with water to provide additional hydration. Some mushers give their dogs snacks of meat, or make a soup-like mixture of hot water with frozen meat. This can include meat such as chicken, salmon, elk, and turkey skins. Bear fat is also loved by sled dogs and can be rolled into balls and then coated in kibble for a high-calorie snack.
While sled dogs are often fed meat, they are omnivores and can also thrive on a vegetarian diet, as long as they get enough protein and other nutrients. Dogs descended from hunter-gatherers, such as the Samoyed and Husky, are poorly adapted to process vegetation. However, dogs that spent time around farmers, such as Western European breeds, can handle large quantities of vegetation due to their ability to produce more enzymes to process carbohydrates.
The energy requirements of sled dogs can vary depending on factors such as body weight, distance travelled, and the type of exercise they are engaged in. For example, Inuit sled dogs in training during the winter require up to 12,000 kcals/dog/day, while open sprinting sled dogs require 4000-5000 kcals/dog/day. It is important to provide enough calories and nutrients to sled dogs to ensure they can perform their essential role in racing or transportation.

The evolution of sled dogs' diets
Sled dogs, also known as mushing dogs, have unique dietary requirements to support their high energy output and maintain a healthy weight. The evolution of sled dogs' diets has been shaped by their working demands, breed, and genetic adaptations.
Early Diets
Historically, sled dogs were primarily working dogs used for transportation and hauling by Indigenous and Inuit Canadians in the Arctic region. The early diets of sled dogs likely reflected the diets of their wolf ancestors, which were mostly carnivorous. Wolves are known to feed on large game, such as reindeer, and other available meat sources.
With the rise in popularity of sled dogs during the late 19th and early 20th centuries, particularly after the Yukon gold discovery, the demand for specialized dog food increased. Commercial dog food companies began formulating nutrient-dense diets specifically designed to meet the high energy requirements of sled dogs. This led to the development of high-performance dry dog food, often referred to as "kibble." Kibble is a convenient and portable option for mushers, who can easily carry it in their drop bags and prepare it by adding hot water during checkpoints.
High-Fat, High-Protein Diets
It is widely recognized that sled dogs have substantially higher energy requirements during racing and endurance activities. To meet these demands, sled dogs are typically fed diets that are very nutrient-dense, high in fat, and high in protein. Fat is particularly important as it provides a concentrated source of energy, with bear fat being a favorite among sled dogs. Sled dogs can consume up to 10,000 calories a day, depending on their activity level and body weight.
Breed and Genetic Adaptations
The diet of a sled dog can also vary depending on its breed and genetic adaptations. For example, dogs such as the Samoyed and Husky, which were domesticated by hunter-gatherers, are less adapted to process vegetation and do better on a meat-based diet. On the other hand, dogs from Western European backgrounds have genetic adaptations that allow them to handle carbohydrates and process vegetation more efficiently.
Pre-Race and Race-Day Diets
The diets of sled dogs may also be tailored according to their activity levels and racing schedules. Pre-race meals are carefully considered to ensure optimal performance. Lean ground chicken or salmon are sometimes used as pre-race meals, providing protein without causing digestive issues. During races, mushers often feed their dogs a mixture of kibble and meat, adding hot water to increase hydration. Meat snacks, such as frozen meat tossed into a soup-like mixture, are also given to the dogs to provide additional energy.

How sled dogs' diets differ from those of other working dogs
Sled dogs have unique dietary requirements, particularly those that are racing endurance sled dogs. They require a very nutrient-dense, high-fat, high-protein diet to maintain a healthy weight and can consume up to 10,000 calories a day. Sled dogs are often fed frozen meat, such as chicken, as well as organ meat, bones, and bear fat. They can also eat a vegetarian diet as long as it is rich in protein and other nutrients.
The diet of a sled dog differs from that of other working dogs in that it is typically much higher in fat and protein content. While most working dogs require a modest increase in dietary energy, sled dogs need a significant boost to maintain their endurance. Sled dogs are generally similar in size and body composition, and their energy requirements are largely dependent on the level of exercise they are undertaking.
In addition, the breed of the sled dog can determine how well they can process carbohydrates. For example, Siberian Huskies have a higher ability to handle carbs than a Pit Bull or Labrador. This is due to the history of domestication and the genetic differences that come with it. Dogs that were domesticated by hunter-gatherers, such as the Samoyed and Husky, are less adapted to processing vegetation. In contrast, dogs that spent time around farmers, such as Western European breeds, can handle larger quantities of plant-based foods.
The diet of a sled dog is specifically tailored to provide them with the energy needed to travel at high speeds over long distances. While other working dogs may have specific dietary requirements based on their job, such as guide dogs or herding dogs, the focus on endurance and speed is what sets sled dogs apart. Overall, the diets of sled dogs and other working dogs can vary greatly depending on breed, size, and energy requirements, with sled dogs typically requiring a much higher calorie intake.

The types of meat sled dogs eat
Sled dogs are direct descendants of wolves and are therefore predominantly carnivorous. Their diets are high in protein and fat, which is necessary to sustain them in the cold weather.
Chicken is a popular meat for sled dogs and is often fed to them in frozen, raw, or ground form. In addition, sled dogs are known to eat other types of meat, including salmon, which is rich in protein but should be given in moderation as it may cause diarrhoea. Sled dogs in Wisconsin have been known to eat leftover organs, bones, and meat from taxidermists, with a particular fondness for bear fat. In colder climates, such as Minnesota, sled dogs may be fed meat from local hunters and trappers, which can include reindeer, cattle, and even horse meat.
It is important to note that while sled dogs are primarily carnivorous, they can also thrive on a vegetarian diet as long as they receive sufficient protein and other necessary nutrients. Their ability to process carbohydrates and vegetation varies depending on their breed and genetic background. For example, dogs with a Western European genetic background may have a higher capacity to handle carbohydrates due to their ability to produce specific enzymes.
The diet of sled dogs has evolved over time, with modern dogs being bred for speed and endurance, resulting in lighter dogs compared to their historical counterparts. This has influenced their dietary needs, with a focus on protein-rich and fatty meats to support their athletic performance and endurance in cold climates.

How sled dogs' food is prepared
Sled dogs require a diet that is high in fat and protein to maintain their energy levels and healthy weight. Their diet typically consists of a base of high-quality kibble, supplemented with meat, organs, bones, and additional fat.
The kibble forms the core of their diet and should be well-balanced, containing approximately 30% protein and 20% fat, along with essential vitamins and minerals. It is recommended to soak the kibble in water before feeding to aid in hydration. As the weather gets colder and the dogs burn more calories, it is important to mix meat with the kibble. This can include beef, chicken, liver, egg, salmon, and bone meal. Some mushers also add salmon oil to the food for its nutritional benefits.
During races, sled dogs are fed a variety of meats, including beef, chicken, salmon, sheefish, and multiple kinds of kibble. Mushers may also provide treats such as bacon, pork chops, steak, or even share their own human food with picky eaters. The food is often prepared as a "'soup'" or thick stew, with warm water and slices of meat. This watery food helps keep the dogs hydrated, and the warm water aids in quickly thawing frozen meat.
The amount of food given to sled dogs depends on their size and energy expenditure. Larger dogs require more food, while smaller dogs need less. It is essential to monitor the dogs' weight and stool consistency to ensure they are receiving adequate nutrition. Typically, during the winter, when the dogs are running frequently in cold weather, they may be fed a total of two pounds of food per day.
In extremely cold conditions, additional fat, such as lard or bear fat, is supplemented into their diet to provide extra energy and help the dogs stay warm.
