PetStar Advanced Version Bark Collar for For Small, Medium Dogs Training System Electric No Bark Control No Harm Warning Beep and Vibration Only, NO SHOCK!!.
How It Works:
When your dog barks, a microphone in the collar picks up the sound and sends an ultra-high frequency sound to interrupt your dog's bark, without hurting his sensitive ears. The tone is annoying but harmless and inaudible to most people. If a second bark occurs within thirty seconds, a more intense tone is sounded. From the third bark, a more intense tone is sounded along with a vibration. This pattern is repeated through 7 correction levels. The first two levels are only with progressively warning tone. If your dog continues to bark through the rest five levels, the more intense sound and vibration are applied until your dog stops for 60 seconds, and then it will automatically reset to the first "tone only" level of correction. If the continuous stimulus reaches the 7 levels, then the Collar will stop working for 1 minutes to ensure protection of the dog.
STOP UNWANTED BARKING THE HUMANE WAY: Petstars Advanced Version Dog Collar stops barking with progressively increasing warning sounds and vibration. In fact, many dogs correct their behavior through the audio feedback alone, and no vibration is needed.
