Working Group dogs were bred to help their humans in their daily lives by doing such jobs as guard duty, pulling sleds and carts, and search and rescues. They have been performing these jobs for longer than history has been recorded.

The Doberman Pinscher, Siberian Husky, and Great Dane are included in the Working Group, to name just a few. Quick to learn, these intelligent, strong animals make great companions. Their large size and strength alone, however, make many working dogs problematic as pets for average families.  Because of their size alone, these dogs must be properly socialized and well trained.

A Great Dane, for instance, can weigh up to 175 pounds. They are easy-going and gentle giant dogs and would not harm a small child on purpose. But because they are huge dogs, they could easily injure a small child completely by accident.
