The device works in three simple phases:
- First – It detects the sound sound vibration of the dog's bark, as soon as the dog that wears the collar bark.
- Second – As soon as the sensor detects the vibration, it delivers a corrective ultrasonic beep that is perceived by the dog in question
- Third - The dog stops barking as soon as the dog hears the irritating ultrasonic sound
Following phases are used by the trainers to teach the dog to bark or to stop barking on command. The trainer knows that the dog is going to stop barking, because the dog bark collar is worn round his neck. So, as soon as the dog starts barking, deliver a command 'NO' (which acts as the corrective command as the ultrasonic sound) firmly and the dog will stop barking – not because of your command but because the device's corrective beep. Once your dog stops barking reward him with his favorite tidbits and praise him lavishly. This lets him know that it pleases when he stops barking and he gets the reward. Repetitive practices with consistency will eventually correct the bad barking behavior.
