The Scottish Terrier (also known as the Aberdeen Terrier), popularly called the Scottie, is a breed of dog best known for its distinctive profile. The Scottish Terrier is one of five breeds of terrier that originated in Scotland. The other four are Skye, Cairn, Dandie Dinmont, and West Highland White Terriers. Its nickname is "little diehard", given to it in the 19th century by George, the fourth Earl of Dumbarton.[1] The Earl had a famous pack of Scottish Terriers, so brave that they were named “Diehards”. They were supposed to have inspired the name of his Regiment, The Royal Scots, "Dumbarton’s Diehards".
