Works wonderful on our doberman. My mom is not able to control the doberman so the collar comes in handy for her. She tells me that she only has to tone him, or use just the vibrate button and on the lowest setting too. This is a great improvement from the one that I had previous to this one. It had been dropped a few times and some of the functions did not work.

I Love it.

Great Item

Very nice.

Absolutely awesome.... It works wonders!

Given as a gift for a very Barky dog---hope it works.
