Dogs are great pets, but if it is out of loneliness or boredom, excessive barking keeps your family up at night and disturbs your neighbors.
This anti-bark collar stops barking with progressively increasing sound and shock which are controlled by a microprocessor distinguishing your dog's bark from other environmental noises and automatically delivers sound and shock after each bark, most of the pets will quickly understand the new sensation is telling them to be quiet. It can be adjusted to control the sensitivity of the voice, according to the size of dogs barking.

2. If your dog continues to bark, the more intense sound and shock will send out until your dog stops for thirty seconds, and then it will automatically reset to the first " tone only " level. If the collar reaches the 7 level, the collar will stop working for 1 minute to protect your dog.
