The Bullmastiff Dog Breed is a very strong breed, fearless at work, docile at home, and large. Bullmastiff is physically imposing but incredibly patient and loving. Bullmastiffs can reach a weight of 59kg, and most of that is muscle. Living with a Bullmastiff brings the responsibility of ensuring that you have a well-trained and socialized dog. When that’s the case, you’ll find yourself in possession of a wonderful dog who is loving, faithful, and courageous, a huggable lug who’s your best friend.
