RM--Your dog is a good sport. Great Danes have so much dignity and I'm actually thinking about getting a rescue GD when we are ready to add another dog to the pack. Either that or a Newfie. What's your pooch's name? Have you thought about getting one of those kid trailers and taking her for a ride? My husband jokes that he's going to get me one and put Agnes, my 96lb golden in it, so I can take my hill climbing workouts to a new level.
