Which breed of dog is this?
The Samoyed is a breed of large herding dog that descended from the Nenets herding laika, a spitz-type dog, with a thick, white, double-layer coat. It takes its name from the Samoyedic peoples of Siberia. These nomadic reindeer herders bred the fluffy white dogs to help with the herding.
The AKC Standard requires 21–23.5 inches (53–60 cm) at the shoulder for males, and 19–21 inches (48–53 cm) for females. The UK Kennel Club Standard requires 51–56 centimetres (20–22 in) for males, and 46–51 centimetres (18–20 in) for females.
Samoyeds' friendly and affable 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.
A Samoyed sentenced to solitary confinement in the yard is miserable, and destructive. These are smart, social, mischievous dogs who demand love and attention. Sammies need a very firm but loving hand in training.
Samoyeds can compete in dog agility trials, carting, obedience, showmanship, flyball, tracking, mushing and herding events. Herding instincts and trainability can be measured at noncompetitive herding tests. Samoyeds exhibiting basic herding instincts can be trained to compete in herding trials.
