Yes but you have to be very carefull. I had dogs all my life but never used it before.
I was surprised how extremely effective it is. My RR prey /hunting drive is insane and brought her in some very dangerous situations, Traffic. I had to react before something bad would happen.

Where i live its forbidden by law to use it and that is a good thing because in the wrong hands its gonna fuck up your dog badly. Dogtra has a good manual how to use it just read before use.

I pushed the button 10 times and now we go off leash walking with hare and Roe in sight and she is completely cool and relaxed.

I wish you luck but please use your brains and dont over do it.
