Samoyed

Samoyeds, the smiling sledge dogs, were bred for hard work in the world’s coldest locales. The Sammy’s famous white coat is thick enough to protect against temperatures as low as minus -60. Powerful, agile, tireless, impervious to cold—Sammies are drop-dead gorgeous but highly functional. Even their most delightful feature, a perpetual smile, has a practical function: The mouth’s upturned corners keep Sammies from drooling, preventing icicles from forming on the face. Samoyeds' friendly disposition makes them poor guard dogs; an aggressive Samoyed is rare. The breed is characterized by an alert and happy expression which has earned the nicknames "Sammie smile" and "smiley dog." With their tendency to bark, however, they can be diligent watch dogs, barking whenever something approaches their territory. Samoyeds are excellent companions, especially for small children or even other dogs, and they remain playful into old age. When Samoyeds become bored, they may begin to dig. With their sled dog heritage, a Samoyed is not averse to pulling things, and an untrained Samoyed has no problem pulling its owner on a leash rather than walking alongside. They will instinctively act as herd dogs, and when playing with children, especially, will often attempt to turn and move them in a different direction.
