Be sure to stick by your dog's side while getting on or off an elevator, especially if it's on a leash. A building's security camera filmed a woman walking into an elevator with her dog, but before her dog can get inside the elevator the doors close! Luckily, a guy who just stepped off the elevator turns around and sees what's happening. He grabs the dog and undoes the leash just in the nick of time. That could have been disastrous for that poor dog.
