In this delightful video, dan Berber shows how ten of his bulldogs get their exercise on ten treadmills. His other dogs get their exercise the old-fashioned way, by chasing after a red ball on a stick.
This is the way I exercise my dogs. I started with one treadmill and now I have 10. Now my dogs have plenty of exercise.
Here’s a video from back in 2013, when Dan only had one treadmill.
