Title: No effect at all
Review: I bought the PetSafe Ultrasonic Indoor Bark Control at PetSmart. It was totally worthless. I tried it for a month with no effect on the three dogs. I took it back and they refunded all my money, which is commendable. It may work on some dogs, but not on the ones at my house.
