What characteristics do the dog German shepherd have?

German shepherds are unique beyond any other dogs. They are amazingly intelligent. They have extremely readable expressions on their faces and sweet unique personalities. They are protective and loyal yet welcoming herding dogs. They are all different. Mine is gentle and tender, a mother who could never have pups, always worrying about the family and trying to do good. My grandma's shepherd, however, is a playful mischief maker who is unique and also unlike any other dog. He loves to bound around the yard and taunt and tease his owners, wagging his tail. Although he tries to protect his owner, whenever someone comes into the yard, he barks protectively, but in a shrill yelping bark. :) Such a funny dog.
