The Scottish Terrier, popularly known as the Scottie, is a breed of small terrier dogs. One of several breeds from the Scottish Highlands, it was originally bred to kill rodents on farms and to hunt foxes and badgers over the tough terrain of the region. All terriers from Scotland being termed Scottish terriers for many years makes it difficult to figure out the exact early history of the breed.

Though there are early records from the 15th and 16th centuries, proper documentation of the breed begins only from the 1800s, when the rough-haired variety of the terrier was clearly identified as the Scotch Terrier, as against the smooth-haired English Terrier, and a pure bloodline began to be developed.

Setting up of Scottish Terrier Clubs in England and Scotland, and increasing participation in dog shows, helped further breeding across set standards. In the US, the Scottish Terrier really caught on in the years between the two World Wars, and has remained a popular show dog and pet.
