Bull Mastweiler
Open each contributing breed for detailed information on the hybrid's parentage.
The Bull Mastweiler is an intentional cross, not a kennel-club breed with a single written standard. Two dogs from the same pairing can differ in size, coat, and temperament, because each puppy inherits a different mix of traits from the contributing breeds.
The portrait is an illustration of one possible look for this pairing. Individual dogs from the same cross can differ in size, coat, color, and build.
A Bull Mastweiler pairs a Bullmastiff with a Rottweiler. This is a large, short-coated guardian dog with a broad head, rust markings, and substantial bone.
Both parents can be protective. Training and socialization are required. They need space and a handler who can manage a heavy dog. This is not a first-dog mix or a neighborhood wanderer.
