D15: Please let me in...

This is my dog. He keeps me safe from the villianous squirrels that live in the back yard. He loves to sit by the sliding glass door while he's on squirrel watch. When he sees one, he starts growling. When I start to the door to let him out, he starts going round and round in circles. He almost caught a squirrel not long ago. The squirrel wasn't paying attention and he was almost on top of it before it went up a tree. I hope he doesn't catch one. He wouldn't know what to do with it and neither would I. This shot is through the sliding glass door. It took three shots to get the flash right so there was no reflection of it on the glass. There's a little reflection of the curtain and dirt from where he paws at the door when he wants back in. Guess I need to clean the door tomorrow.
