The Brottweiler is a portmanteau, or an arbitrary name derived from two words, for the result of a cross between a purebred Brussels Griffon and a Rottweiler.
The Brussels Griffon is classified as a toy dog, and there are three varieties, which are considered to be disparate breeds in some countries. Aside from the Griffon Brixellois, there is the Griffon Blege, and the Petite Brabancon. Differences are mainly in coat type and color, but otherwise, other breed standards remain the same.
The Rottweiler is a heavily muscled German breed, originating from the town of Rottweil as a farmer's working dog, driving and guarding herds of livestock. Its size and fearlessness also served to guard its master from robbers and thieves as he traded and did business in the market.
