Moose-dog has developed "old man dog syndrome". He no longer feels it necessary to be "the good boy" that he has always been.
For years, when he got scared, he would crawl behind me on the bed. Now he does it for a variety of reasons - mostly because he has decided he prefers my spot on the bed - and he literally shoves me off the bed. He ignores me completely whenever he doesn't want to do what I want him to do. He has to be reminded to go outside before bed (he will go if I insist, but otherwise will wake up in the night and need to go immediately). He prefers to sleep as late as possible.
Nothing abnormal, no illnesses, etc. He has just decided that he deserves whatever he wants because he's been so good for years. I can't really argue with that logic. His hips are going and he's old for his breed mi, so I just put up with it and tell folks "he's got old man dog syndrome".
