Bull Daniff (Great Dane x Bullmastiff)

The Bull Daniff is a large designer breed, inheriting the huge size and protective nature of both its parents. With the Bullmastiff as one of its parents, this breed is likely to inherit their guarding instincts. They could have an independent nature like the Bullmastiff, making the training process a little challenging. These dogs would suit better for an experienced owner rather than a first-timer.
