Yes, we have a female Bullmastiff called Maddy, she was big and ugly looking and when i first met her i was scared so much (especially when walking her as she liked to lunge for other 狗 and noisy vehicles) but i soon learned she was as soft as anything.
The only other dog we had i was intimidated of was our 罗威, rottweiler, 罗威纳犬 called Max. He was a lovely dog, but suddenly and for no known reason he turned on my little brother Anthony while he was making a 三明治 in the kitchen, and if my younger sister Sophie hadn't been there at the time, Anthony would have 迷失 his hand. Unfortunately his 前一个 owners wouldn't take him back, so we sent him to training to see if anything could be done, unfortunately he bit one of the trainers after receiving high marks on his finishing certificate (odd i know) she pressed charges so he was sadly put down.
