1. Human bark collar with 2 modes-in 96% cases, helps to reduce (eliminate) the dog's barking by automatic output with 5 levels of safe tone (beeps) and vibration. Beeps and vibrations automatically turn on based on the amount of dog barking and increase after each bark.

2. Rechargeable version-no bark collar works about 14 days with 1 battery life. Get a full charge in 2-3 hours.

3. Action without remote control - the collar works in automatic mode, combining sound and vibration to stop barking effectively and safely. With the first bark there is only a sound signal, with the subsequent barks vibrations are added to a sound signal. Useful when you are not at home and your dog is left alone.
