This collar is a very effective behavior modification device to help train your dog to reduce / stop nuisance barking. Triggered by your dog's bark vibration, you can set the collar to emit either an ultrasonic only or ultrasonic + audible sound. Your dog will quickly learn to associate barking with the ultrasonic beep of the collar. This is an effective training device to control your dogs excessive barking in a non harmful way (unlike some other bark control products on the market).
