Lentek Bark Free - Ultrasonic Dog Training Device!

Bark Free has a specially designed sound selector that lets you choose ultrasonic frequencies which can only be heard by dogs and cats, or lower sound tones audible to human ears. Bark Free uses an old age principle of "Negative Reforcement using Sound" to help train dogs to stop annoyance barking. Tired of Rover barking all the time? Or how about the neighbor's dog keeping you up at night? You need Bark Free, the latest product designed to control dogs' nuisance barking. No, not another bark control collar!! Bark Free doesn't attach to the dog and "SHOCK". Bark Free sits on the counter or mounts outdoors. It uses a specially designed speaker that picks up a dog's bark and then sends out a corrective tone to keep Fido from waking you up or the neighbors. Persistent barking and bad behavior in dogs is often difficult to cure. The Bark Free, developed by veterinary technicians in the U.S.A., is a humane and effective way to help cure your pet's behavioral problems. When placed near the neighbor's or your own dog, Bark Free is designed to turn on automatically when barking occurs. Bark Free uses a unique "Bark Pickup Sensitivity Adjustment Selector" which allows the user to set the microphone to activate to the dog's bark. This eliminates the chance of any false sound readings and automatically turns off when barking stops. To determine the best sound frequency for preventing barking, Bark Free also has a specially designed "Audible Sound Selector".
