Lentek PC06 Bark Free Ultrasonic Dog Barking Deterrent

The Lentek Bark Free Ultrasonic Dog Barking Deterrent has been designed to control nuisance barking. A specially-designed sound selector lets you choose ultrasonic frequencies that can only be heard by dogs and cats, or lower sound tones audible to human ears. Bark Free uses the principle of ""Negative Enforcement using Sound"" to help train dogs to stop annoyance barking. Bark Free doesn't attach to the dog or shock the animal. 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 up the neighbors. Persistent barking and bad behavior in dogs is often difficult to address. Bark Free is developed by veterinary technicians in the U.S.A. and is a humane and effective way to help address your pet's behavioral problems. Bark Free is designed to turn on automatically when barking occurs. This device 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 the device automatically turns off when the dog's barking stops.
