I got some of those house training bells that go on the door for the dog to ring when they need to go out. Sharlette always digs at the back door when she wants out but I don't always hear her if I am not in the same room. So I decided to get the bells. I didn't expect her to use them right away. In fact I never even showed her how yet when she went and used them for the first time. she used them a bunch of times after so I set up the camera in hopes to catch her using them. here is the video. ENJOY!
