things can start hurting and not working right when you get old, sometimes onset of pain can cause separation issues even if they didn't exist before. I heard of one woman who had a dog that would bark horribly when she left but stopped after having a rotten tooth remove. A overall good bill of health and maybe a blood panel screening could give you some insight as to if anything is going on that isn't obvious. In the mean time your probably best to leave him in a easy to clean space.
