The Siberian Husky is a medium size working dog breed that originated in north-eastern Siberia, Russia. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred double coat, erect triangular ears, and distinctive markings. The original Siberian Huskies were bred by the Chukchi people — whose hunter-gatherer culture relied on their help. It is an active, energetic, resilient breed, whose ancestors lived in the extremely cold and harsh environment of the Siberian Arctic. William Goosak, a Russian fur trader, introduced them to Nome, Alaska during the Nome Gold Rush, initially as sled dogs. The people of Nome referred to the Siberian Huskies as “Siberian Rats” due to size and weighing 40 to 50 pounds when compared to the Malamute dogs.The Husky howls rather than barks. They have been described as escape artists, which can include digging under, chewing through, or even jumping over fences. Because the Siberian Husky had been raised in a family setting by the Chukchi and not left to fend for themselves they could be trusted with children.The ASPCA classifies the breed as good with children. It also states they exhibit high energy indoors, have special exercise needs, and may be destructive “without proper care”.
