Only the dog's barking will activate the collar. You can test its function by blowing or shouting into the microphone on the back of the receiver. 【Rechargeable Waterproof Anti-Barking Collar】—This collar comes with a USB rechargeable battery. A full charge takes approximately 2 to 3 hours and provides up to 15 days of battery life.
