People where I live do not control their vicious dogs in or out of my new apartment complex. On a fixed income, dog training was not possible (new widow). I ordered the PetGentle, and honestly, I flashed the PetGentle immediately as she heard a dog barking, and I pointed the machine directly at her face and pushed the button. She stopped barking, and shook her head...I praised her, and then she smiled back at me. Not once, twice, three times, etc., but EVERY time she barked and I have repeated now for a month now. If I start to sense an "eruption", I touch the PetGentle and she stops, looking into my face for my praises!
Well worth having. My husband would be so proud!
Bottom Line: Yes, I would recommend this to a friend
