Do you try to involve your dog with your own interests and hobbies? For example, if you go sailing does your dog go with you? Or if you are a camper, does your dog come along? Obviously, it is rather more difficult for things like chess and reading! Since most of our hobbies were musical in nature, it was rather difficult to involve a dog. I am sure they heard and listened. One of our dogs use to start howling if he heard a recorder!
