Purchased this collar to help train our strong willed Golden /Lab mix. I was hesitant, but after using this collar found it extremely helpful and easy to use.

I have a very strong headed German Shepard puppy (about to be 1 year). I was at the end of my tolerance with him. I had even sent him to 7 weeks of training where they had him walking in public without a leash. But as soon as he got home, he remembered he was in charge here and back to not listening and doing what he wanted.

Bottom line is this is a great collar!
