When the dog collar device is active and properly fitted on the dog, it detects and corrects barks automatically. The dog collar device starts at the lowest intensity level and increases the intensity level gradually until the dog stops barking. When the dog is quiet, the intensity decreases over time.

The status LED flashes briefly when the dog collar device detects motion or corrects a bark.
