 Third time in the last few months, Millie has chewed the wires that control my garage door. You know where your little sensor is? Yeah. Why is she chewing that? Now, when you do that and you don't have that, it's like there's something in it so it won't come down. You can get it to go up, but it ain't coming back down. No, it's not. And for the third time, I've had to go. I figured it out.
