I'm really nervous about putting a barking collar on my dog. But I need to do something. It's time for some training. The dog is barking! This collar is one of the best things we have! When the big dog decided to bark at the leaves blowing from the tree across the street, the collar emitted a small beep. Then he felt the carpet calling his name, and tried to scrape the beeps below him, but soon he realized that this was happening in his bark! Now, puppy.
