"This is my two year old Staffordshire Bull Dogue De Bordeaux, Molly. Very sound temperament. Not at all dog aggressive and the kids adore her. Suffers occasional bouts of deafness when being nosy, but once something has been explored her hearing returns to normal."
The Staffy Bull Bordeaux is not a purebred dog. It is a cross between the Staffordshire Bull Terrier and the Dogue de Bordeaux (also called the French Mastiff). The best way to determine the temperament of a mixed breed is to look up all breeds in the cross and know you can get any combination of any of the characteristics found in any of the breeds in the hybrid. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generation crosses.
