I have an 8 year old mini schnauzer. I don't have a "problem" with him, but I do see a curious behavior with him. He usually sleeps with the family on the bed, moving from one bed to another as he desires. I am usually the one to stay awake the latest, and I have my lights on in my room, so he tends to come to my bed and sleep by himself while I am on the desk. Sometimes though, he would sit or lie on the couch in the living room by himself, in the dark, and groan and moan. He would continue until I go to look at him, at which point he jumps down from the couch and heads into my room, and gets on the bed to sleep. I always leave my door open, so its not like he's asking to be let in either. I am just curious about this seemingly pointless act of getting my attention. Any thoughts?
