We have a german shepherd, he is very headstrong....this collar worked great to get him to stop terrorizing the two neighbors for fun! He gets a beep first then only one time did we have to low shock him before the beep worked just fine. He wears it whenever we are outside. Now we are working on the grumbling he does because his previous bark collar he figured out that he could grumble and not get shocked!

Overall, this is a good product and has helped.

I would gladly recommend this collarHad great results.

This is great! It does the job, easy to use and Love the design.how amazing is that.thanks

It was difficult to watch as it is not entirely pain freeIt works great, my dog responds very well to it.

I hope someday he probably won't need it anymore and that will be the final goal of this wonderful product.
