Around 20 years ago I was in a race that finished with two laps of a 13 mile loop out in the country. Being in the last third of the pack, I saw a small-ish dog run directly into the pack ahead of me. The dog ran directly under a team-mate's rear wheel, causing him to bounce in the air, but fortunately not crash. It was a strange sight as the group parted ahead of me and the dog tumbled down the center. On the next lap, the dog was barking from the porch.
