Boxer (dog)
The Boxer was bred in Germany and was originally bred for bull-bating and dog fights, but when that was ruled out they were used as hunting dogs and farm dogs and just regular house pets.  The Boxer breed was created from the brabanter and Bullenbeiser. Though originally bred to fight and later used as a military sentry or police dog, Boxer owners will confirm that this type of role is no longer suitable for Boxers, as many decades of breeding had produced a dog that is too docile for this type of duty.
