Delbert, a 150-pound Alaskan Malamute from Cascade Kennel, currently holds the dog weight pulling record at 5,400 pounds pulled to the finish line. The AKC adds that the following breeds are best for sled pulling:
Samoyed
Alaskan Malamute
Siberian Husky
Chinook
They also explain that many breeds were developed to pull heavy loads to assist their owners and add that many dogs enjoy the sport of weight pull, which enables dogs to put on a special harness and pull a cart loaded with weight, often bags of dog food.
The sport of weight pulling is based on traditional sled dog racing, where teams of dogs would pull a sled loaded with supplies or people across snow-covered terrain.
In modern weight-pulling competitions, dogs are instead asked to pull a heavy sled or cart a distance. These events are held indoors and outdoors year-round, and dogs of all shapes and sizes can compete.
While there is no definitive answer to which dog can pull the most weight, breeds that are typically strong and have a lot of muscle mass, such as the Alaskan Malamute or the Siberian Husky, are usually the top contenders. However, any dog in good physical condition and has a strong drive to pull can be successful in the sport of weight pulling.
