Spitz (German: "pointed") is a domestic dog characterized by long, thick, and often white fur, and pointed ears and muzzles. The tail often curls over the dog's back. Smaller breeds resemble foxes, while larger breeds resemble wolves. The exact origins of Spitzes are not known, though most of the Spitzes seen today originate from the Arctic region or Siberia.
Spitzes are well suited to living in harsh northern climates. They often have an insulating, waterproof undercoat that is denser than the topcoat to trap warmth. Small, upright ears help to reduce the risk of frostbite, and thick fur that grows on the paws protects the dogs from sharp ice. With their thick fur, fluffy ruffs, curled tails and small muzzles and ears, Spitzes have been bred into non-working dogs designed to be companions or lap dogs.
