This special collar has a little sensor so that when I start barking randomly, especially in the middle of the night, the little ultrasonic beeper goes off, reminding me to stop barking. I do not mind it, and am pretty used to it. In fact, sometimes my owners forget to put the battery in, but I still know not to bark while the collar is on me. So when I have my red bark collar on, I am quiet like a ninja in the yard and in the house. Maybe the poor puppy down the street should get one of these so he can learn not to bark randomly.
