Review on 🐶 PetSafe Multi-Room Indoor Dog Bark Control - Ultrasonic Device (2 Pack) by Glen Sprout

This product is designed to make a high pitched sound when the dog barks. This product totally spooked my dog and he didn't even bark when it was on! I had it one afternoon and she was acting so strange, totally scared and shaking, hiding under the edge of the table. I thought it was a storm going through the area (although it wasn't a big storm and she shouldn't have been scared). I didn't use it again until a few days later when she settled into her favorite chair which was completely covered with a blanket (head and all), I walked over and turned it on and she immediately got up, jumped off the chair and left the house . the number wobbles terribly!
