The Ultrasonic Bark Control is an easy-to-use unit designed to stop dogs from nuisance barking. Designed for indoor use, the Ultrasonic Bark Control can deter your dog’s bark safely from a range of up to 25 feet. The Ultrasonic Bark Control is sleek and unobtrusive and can sit comfortably on a small table or counter-top. The Ultrasonic Bark Control creates a “quiet space” for all dogs in its vicinity. The Bark Control unit can be set to produce its sound automatically by a dog's barking, or manually. When a dog barks, the Ultrasonic Bark Control emits an ultrasonic tone that you won’t hear but will be very loud for your dog. This unpleasant noise surprises your dog and your will quickly associate the barking with the unpleasant noise and greatly reduce his barking. This unit is cordless and requires a 9-volt battery.
We are all really happy with the Bark Control. It sits by the front door. The dogs still bark when someone comes to the door, but they stop when told "that's enough!" instead of continuing to bark long after the person, even those they know, are in the house. Great invention. Thanks!
