I use it to control their barking at strangers when they passed by with other dogs and our dogs, as soon as they hear the music sounds from the collar, will stop barking and returned inside the house immediately. Very please with this collar and strongly recommend it to anyone with problems training their dogs.

I bought this collar a approx.. 2 months ago. It arrived very fast.

I just got a new dog, only 10 months old, from a family with small children. As a result, my new lab/boarder collie loves children and wanted to follow them down the road. I love the fact that I can use the tone button as a replacement for "come" and the vibrate mode to warn him. I hate the thought of shocking my dog but even on the low setting he learned quickly. I no longer have to tie him up and he now checks on me every 5 minutes or so, or I remind him with a quick tone. I love this unit and the company stands behind their product. I recommend this product, it's worth every dime....
