The Siberian Husky (Russian: Сибирский хаски, tr. Sibirskiy khaski) is a medium-sized working dog breed. The breed belongs to the Spitz genetic family. It is recognizable by its thickly furred double coat, erect triangular ears, and distinctive markings, and is smaller than a very similar-looking dog, the Alaskan Malamute. Siberian Husky tails are heavily furred; these dogs will often curl up with their tails over their faces and noses in order to provide additional warmth. As pictured, when curled up to sleep the Siberian Husky will cover its nose for warmth, often referred to as the 'Siberian Swirl'. The tail should be expressive, held low when the dog is relaxed, and curved upward in a 'sickle' shape when excited or interested in something.
