She's fat, right? That has to be it. And stuck inside the tub somehow. That's the only reason I can see needing to train a dog to do this sort of thing.
This made me think of my mom's dog, a mystery schnauzer who would shut the door when she came in, put her toys away when she was done playing, shuttle notes and things around the house to "Mommy" or "Daddy", and pull weeds in the garden.
So I guess four stars for reminding me of a really good dog.
