I have a three-year-old German Shepherd. She is loud, and she is stubborn. I got the PetGentle to try to stop the barking when anything goes past our house, as well as stopping her desire to chase cars while on walks. I have to say I was amazed at the results. It stopped her barking almost immediately, along with the command "calm" and a treat. She watches cars go by, but no barking. The car chasing is proving a bit harder but even there it is making a big difference. I would recommend this to anyone with a similar issue with their dog.
Bottom Line: Yes, I would recommend this to a friend
