A girl I went to school with has one of those XL bully's.
He is absolutely HUGE.
He's used as a guard dog for the house and also as a pet. She runs an aesthetics business from home and regularly posts reminding her clients to text her before they go through the gate as he'll attack otherwise.
Then in the next post, it's a picture of her two daughters under 10 laying on him in bed. Makes me shudder.
She is tiny, I'm talking 5ft, size 6 and walks him on one of those chain leads and I always think to myself that the moment he chooses to overpower her, she stands no chance.
