Cairn terrier is a breed of dog that originated in the highlands and island regions of Scotland. It received its name because of its ability to dig under cairns (heaps of stones) to hunt rats and other animals. The terrier’s broad, short head looks more like that of a cat than that of a dog. Its ears are wide apart, and the dog holds them erect. The cairn has a hard wiry topcoat and an undercoat of soft fur. Its coat may be any color but white. It weighs from 13 to 14 pounds (6 to 6.4 kilograms).
