I ordered the "PetGentle", and the first time I used on my Australian Blue Heeler, he responded. My Chihuahua was nearby, and the device TRAUMATIZED him! Every time my Chihuahua saw the PetGentle, he would run and hide, wouldn't stop shaking, and wouldn't leave our sides when he wasn't hiding, had panting spells. So besides the $110.00, I paid for the three PetGentles, which should have only been two PetGentle. I also had a $120 vet bill. The vet said the chihuahua was traumatized, and gave him some medicine to help him calm down. MY advice: DO NOT USE ON SMALL DOGS!
Bottom Line: No, I would not recommend this to a friend
