A sheepdog is a dog bred or trained to work with sheep, either by herding them or guarding them from predators. The term also refers to several specific dog breeds that were developed for livestock work, including the Old English Sheepdog and the Shetland Sheepdog. Sheepdogs are familiar to Canadian readers through farm livestock management, dog breeding, and popular companion breeds such as the Shetland Sheepdog and Old English Sheepdog.

Meaning of the term

Sheepdog is a general term for dogs used in sheep work. It includes dogs that drive, gather, or control sheep, as well as dogs that guard flocks from predators or poachers.

Working roles

Herder-type sheepdogs move livestock through fields, roads, or pens. Guardian-type sheepdogs live with flocks and help protect them from threats.

Breed examples

The term appears in the names of several breeds, including the Old English Sheepdog, Shetland Sheepdog, Maremma Sheepdog, and Polish Lowland Sheepdog. These breeds differ in size, coat, and exact working purpose.

Use in agriculture

Sheepdogs have long been important on farms because they reduce the labour needed to manage flocks. They are especially associated with pastoral farming traditions in Europe.
