5. For the duty-bound: German Shepherd
For someone who always plays by the book and wouldn’t even dream of exceeding the speed limit, the German shepherd may be the perfect companion. There’s a reason these large and sometimes intimidating dogs have been used by law enforcement agencies and the military for many years. German shepherds are very eager to please and they will put themselves in harm’s way on command without hesitation. It’s hard to beat this breed where duty, loyalty, and obedience is concerned.
