A Big Little Dog
The Cairn terrier really is a big little dog. Though he stands only about 10 inches tall and weighs just 14 pounds, he is sturdy and strong.
In the personality department, there is nothing small about him.
The Cairn’s ancestors are from the Scottish Highlands. This breed was known for its working ability and intelligence, according to the Cairn Terrier Club of America. Over time, the West Highland white terrier and Scottish terrier evolved into their own distinct breeds, with the Cairn staying the closest to his roots as a small, tough working dog.
