Shadow Dog

So last night as I am laying in bed. Auddy growls. I think he is growling cause the tenants are getting their laundry. But then I notice he is not looking that way. He stands up, and sniffs, leans closer to the edge of the bed sniffs again, sticking his nose way out over the bed. I am very confused about what is going on. He then starts moving and going into his playful bow. I realize that he has just tried to play with his SHADOW. It was so cute.
