Bullmastiff
The Bullmastiff is a large and powerful British breed developed in the nineteenth century by gamekeepers who needed a courageous, silent dog capable of apprehending poachers on private estates.
Created by crossing the English Mastiff with the Old English Bulldog, the breed combined the Mastiff's impressive size and stability with the Bulldog's determination, resulting in an ideal working companion.

About the Bullmastiff
Standing 61 to 69 centimetres at the shoulder and weighing 41 to 59 kilograms, the Bullmastiff is a massively built dog with a distinctive broad, wrinkled head and short, dense coat in fawn, red, or brindle, always featuring a dark muzzle. Despite its formidable appearance, the Bullmastiff is typically gentle and deeply affectionate at home, showing remarkable devotion to its family and surprising patience with children when properly raised. The breed is confident and self-assured rather than aggressive, often using its commanding presence as an effective deterrent. However, the Bullmastiff's considerable strength demands experienced, consistent training and early socialisation. These dogs require more than two hours of daily exercise and thrive best with committed owners who can provide firm guidance. With proper care and attention, the Bullmastiff makes an impressive, loyal and steady family companion.
