Quick tip for those of you with little, bitty "purse" pooches, do not allow your small dog to EVER walk through a revolving door.
Today, I witnessed the wagging tail & torso of the little small dog on one side of the door and the head of the dog on the other side of the door. Not good.
In the end, the story ended happily, as both owner & pooch walked out just as dumb as they were when they walked in. Amazing.
