For your pet's safety, the collar features a built-in protection mode. If the collar is triggered 7 times within a 1-minute period, it will automatically stop functioning for 2 minutes. After this 2-minute safety period, the collar will resume normal operation.
The collar is designed to activate only when your dog barks. Other nearby dog barks or sounds should not trigger the collar.
