Breeds in the working group were originally bred to perform labor intensive tasks to assist human beings in their daily lives. Working dogs tend to be bigger, stronger and more robust than other dogs. Common tasks have involved the guarding of property and goods, transportation across land, pulling items up inclines, the guarding of nobility and aristocracy, as well as tasks involving general protection, safety and rescue etc.
Some popular guard dogs include the Boxer, the Great Dane, the Doberman Pinscher, and the Saint Bernard. Lesser known breeds in the working group include the Samoyed, Kuvasz, and Black Russian Terrier. Many of these dogs are not suitable choices for first time dog owners. However, with careful research and training, working breeds can become valued members of the family.
