Have you seen my mate

My dog is a CLEPTO. You would not believe the things I find on my porch. One time there was a little purse. I am sure it was just a little girls, but it has lip gloss, finger nail things. He stills other dogs toys as well. On numerous occasions he has come home with some brand new very large rawhide bones. Both our neighbors have Labradors. This is what I found today...
Poor little slipper is missing its mate. Maybe tomorrow he'll bring the other one.
