Description:
The dog is our friend, but sometimes its barking bothers us. Unexpected barking often disturbs neighbors. How do we help our dogs become more gentle?
This is the New Humane Ultrasonic Anti No Bark Control Device Stop Dog Barking Silencer Hanger, which triggers the ultrasonic wave circuit to work through barking, sending out a five-second harsh ultrasonic wave to stop the barking. The dog will build up a conditioned reflex after many repeated actions, learning that the extra sound was caused by its barking. Afterward, the dog would not bark without reason. In general, this product will trigger after more than three barks. With this product, you will be liberated from annoying barking and will create a quiet environment for you.
