Bred by the nomadic Samoyedic people of Siberia 3,000 years ago for reindeer herding, sled pulling, and (uniquely) sleeping with the family for warmth, the Samoyed retains its uncanny human-bond to this day. The famously upturned mouth corners — the 'Sammy smile' — prevent drool from freezing. Spectacularly fluffy white double coat, friendly with everyone, including kids and strangers. The cost: epic seasonal blowouts, intolerance to heat, and a tendency to howl when bored or left out.
