Review on Collarless Remote Trainer by PetSafe - Handheld Ultrasonic & Tone Dog Training Device - Correct Barking, Digging, Jumping Behavior - Similar to Electronic Dog Whistle, No Collar Needed by Jeremy Therrien

I took my naughty dog to a sawmill where the dogs are friendly. My dog goes nuts when he sees another dog and sometimes even people scare him and he's downright obnoxious. A good couple saw my problem and mentioned this product. I don't remember taking it to the store, but it helped me in other ways. When people approached my car she went crazy, very embarrassed. All it took me was to use this thing a few times, she figured it out and now people think I have a different dog :)
