Here's a video that every dog owner should see, just to learn a valuable lesson. And that is, stay glued to your dog's side while getting on or off an elevator. Especially if it's on a leash.
A building's security cam filmed a woman walking onto an elevator, but the doors close BEFORE the dog can get inside. Luckily, a guy who just got off sees what's happening, and he grabs the dog and undoes the leash just in time.
