This dog is trying to warn his owners about something going on in the house by barking, but he is too comfortable on his dog bed that getting up and out of the bed to motion to whatever it is he is barking about is out of the question. But now that we think about it, could the dog be complaining about something else instead? Whatever it is he is trying to say, all we see is a cut and lazy dog on a bed.
