Bred to be small sheep dogs suited for the terrain of Scotland's
Shetland Islands, the Shetland Sheepdog ("Sheltie") is an outstanding
and loyal companion, lively, intelligent, trainable, and willing to
please and obey. While they're affectionate with their family, they
can be aloof with strangers and should be socialized extensively.
Shelties do especially well with children if they are raised with them
from an early age.
With a still strong herding instinct, some Shelties may try to "herd"
groups of people by running around, barking, and nipping at heels.
Shelties have a double coat with a long, straight, water-repellent
topcoat, and a short, furry, and very dense undercoat which helsp keep
the dog warm. They typically only need to be brushed once or twice a
week. Shelties do best with a sensitive, yet firm, owner and are
highly trainable.
