I'm sorry you were frightened by your friends pit bull. She really does need to get him neutered that would help a lot. Also, she shouldn’t tolerate that kind behavior from her dog. As, the owner of a pit bull myself you have to be top dog over them. It sounds like the dog runs her. Have you suggested she do the nothing in life is free with her dog? It really does work wonders. Does your friend give her pit bull any type of exercise? They are such high energy dogs they need lots of exercise. Pit bulls are such good, loving dogs but the owners must do right by them. So many don’t. My Ebony is a big marshmallow she loves people and kids. I wish you could meet her, I know you would love her she wouldn't scare you at all.
