I've been searching for good TV for visiting mom who has dementia and we just finished watching a fantastic 3-part series on Nat Geo Wild which was available On Demand through my cable provider: The Wonder of Dogs. It talks about the history of dogs, their intelligence and working lives, and their emotional capacity. I'm making it sound boring but it really well-done, fun, and captivating, for both mum and me. I would highly recommend.
