Bull Mastiff M.

This was the best decision I made on purchasing this collar. I bought a cheaper one initially and it had no effect on my stubborn Bull Mastiff. With this collar, now I have an extremely well behaved dog that will listen to me and can have off leash. I merely have to hold up the control and she will listen (the collar won't even be on her). Highly recommend for stubborn, large breeds. This is my third Bull Mastiff, but first female, and she was a challenge until I purchased this collar.....never needed something like this for my males.
