Canine Body Language: the dog in the photo is a German Shepherd. Get to know your dog and pay attention to his own body language. It will be helpful when introducing him to new situations and handling them appropriately.
Another Pinner said: Yes, German Shepherds can bite harder then pitbulls. That's why they make such efficient cop dogs. Nat Geo tested the bite force of a pit, Rott, and GSD, and the German Shepherd came out as having more PSI then the Pit Bull.
