The Shetland Sheepdog, or "Sheltie" as it is commonly called, is essentially a working Collie in miniature. A rough-coated, longhaired working dog, he is alert, intensely loyal and highly trainable and is known as a devoted, docile dog with a keen sense of intelligence and understanding. Agile and sturdy, the Sheltie is one of the most successful obedience breeds, but also excels in agility, herding and conformation.
