The uncanny popularity of Great Danes in my area has raised a big question in my mind - do these dogs require ANY exercise? I know at least a half dozen who get walked around the block twice a day, and another 4-5 who get turned out into a small yard to relieve themselves, and that's it for their outings. I've heard that the giant breeds require less exercise than more energetic medium breeds, but isn't this a bit extreme? Don't they need to get out more, just for their mental health, if nothing else?
