Yes, I have seen that show, David. I actually watched it for the first time on the Jet Blue plane from JFK back to Ft. Lauderdale a week ago Saturday - it was about an unruly Great Dane and a pack of Weimeraners who had taken control of their owner's house (because she did nothing to exercise or discipline them). In the latter case, the trainer goes, "You don't exercise them AT ALL? What are you thinking, taking a working breed and not taking them for walks?"
Our girls love their walks. They go on four or five a day - a couple for 1-2 miles. They wag their tails and trot along the whole time. Can't figure out why I'm not losing any weight yet, since I take them on the vast majority of them. But that's beside the point.
