4 Adjustable Sensitivity Levels and LED Indicator: The anti-bark collar has 4 levels of sensitivity that can effectively detect barking from dogs of all sizes. Select a sensitivity level based on your dog. 4 being the most sensitive, and 1 the least sensitive. LED indicators let you know what level you are on, what mode and even the status of the battery when it is low. Intelligent training mode and automatic protection system: The two training modes are Sound + Vibration and Sound + Vibration + Shock. The anti bark collar for dogs does not need a remote control. On the second mode (with shock), the collar will make 6 corrections, pause for 2 minutes and then resume again. Better management of interference: The bark collar is equipped with a smart sensor that works in tandem with a chip to effectively detect the barking of the dog wearing it, while filtering out interference. The collar is activated only when the dog wearing it barks, and this very quickly. Rechargeable and waterproof
