A poodle I had for many years watched out for me. On occasions when a group of us would go to an old swimming hole not far from home she was fine with just watching me from the banks. At a certain point, however, she always decided I had been in long enough. She would swim out to me, grab my swimsuit by the strap and tow me back to land. I would remonstrate with her but never scolded her for it. Thought maybe she knew something I didn't. :)
