Title: My skepticism for this product held true
Review: My two collies that I love more than life itself are always on guard, and their protective instinct means that they're quite "talkative." I'm a natural born skeptic and, of course, I was skeptical about Bark Free from the beginning, but I thought I'd experiment with such a device and purchase one. When I received the Bark Free I followed the instructions and plugged it in. I had it set on the audible setting that emits a horrid squuuuuuueeeeecch whenever my dogs would bark. It actually quieted my dogs, but for only a few hours, they got used to it and were barking again. I set the device on the ultrasonic setting which supposedly is audible only within a dogs hearing range and at that setting was completely ineffective. Indeed my skepticism held water, the product failed. The product claims that it works with all breeds of dogs, obviously not! Don't waste your money on scientifically unproven devices!
