Alaskan Malamutes. This large-bodied dog was originally bred for its strength and endurance in carrying heavy objects. Not only that, Alaskan Malamutes are also often used to pull sleds, there is even a special sled competition that uses Alaskan Malamute dogs!
The Alaskan Malamute shares DNA similarities with other dog breeds, such as the Greenlandic Dog, Siberian Husky, Canadian Eskimo and Samoyed. The similarity between them is that they are both big-bodied dogs, have thick fur and are physically strong.
