The German shepherd is one of the cleverest breeds of dog, with only the border collie and the poodle being considered more intelligent. The German Shepherd dog was originally bred to herd sheep. But no matter what task you give it, it will take on any challenge enthusiastically and master it with unparalleled determination and great courage. Therefore, it is also ideal as a guide dog, a dutiful guard and police dog, and as a reliable rescue dog. When well trained, it is also a great family dog and very chield-friendly. But the energetic, active dog would not be satisfied with a life on a sofa.
