I have never lived in a place where I had to take an elevator to get to my home.  I have dogs but they have always had free reign of the backyard, to run around and do their business.  I don't have to take them out for walks or to potty.  When you live in an apartment building you do have to do things like that for your animal.  However, it is always a good idea to make sure your dog is in the elevator with you before you hit the buttons or you could have something like this happen.

You cannot help but feel the pain this man feels when he realizes that he might have just killed his dog.  Luckily all the dog got was a scary 7 ft ride before the leash broke.

Thank goodness the dog wasn't hurt.

Moral of this story:  If you live in a place where you have to take an elevator and you have a pet, always make sure your pet is in the elevator with you before you close the door.
