Professional Bark Stop-Ultrasonic Barking Dog Control Trainer uses innovative Dual Sound System technology that takes advantage of the sensitivity of dogs' ears, maximizing the effectiveness of Professional Ultrasonic Bark Control's ability to train your dog to stop barking. The Professional Ultrasonic Bark Stop is a barking deterrent system that uses an ultrasonic tone to teach your dog or neighbor's dog to stop barking incessantly. When the Professional Bark Stop senses your dog's bark, it emits an irritating sound that your dog will hear up to 35 ft. away. Your pet will quickly learn that his bark triggers this noise and will stop barking without provocation.
