I get the most hysterical laughter from people in the first mile or two when I take my husky with me. He's so hyped at getting out for a run that he'll rip me along at a full out run. So, there goes a weird looking, low to the ground trike with a heavy set woman on it and a gray and white husky dragging her along almost uncontrollably. I had someone fall into the hedge they were laughing so hard once.
Thankfully, the dog settles down after those first couple miles, or I'd never get any exercise with him along.
