How does a Shetland Sheepdog look like?

A Shetland Sheepdog, also known as a Sheltie for short, is a strong, nimble, lightly built, beautiful dog, with a long, wedge-shaped head. Its coat is rough with a soft undercoat. Some say they are almost a perfect miniature copy in of the long-haired collie. The top plane of the muzzle should be parallel to that of the skull. The glorious long double coat sports a lion-like mane and frill around the neck, and comes in blue merle, sable and black with various amounts of white and/or tan. The outer coat is lined with a dense, woolly undercoat. The legs and long tail are feathered, and the hair on the face and feet is smooth. The tail should reach to the hock. The almond-shaped eyes are generally dark, except in blue merle dogs where they may be blue or merle color. The dog should have a watchful, gentle, questioning and intelligent expression. The nose should be black. The teeth should meet in a scissors bite. The ears are small, flexible and expressive, with dropping tips. The Sheltie is an agile, swift dog and a good jumper.
Height: 13-16 inches (33-40.6 cm.)
Weight: 14-27 pounds (6.4-12.3 kg.)

To simplify, they look like Rough Collies only smaller.
