TangleDog 2011: Canine Joins Paceline to Show Support for People with MS

I can not prove this large young dog was not just jealous of our fun and wanted to jump in to exercise to help people with multiple sclerosis. So I will just say I am glad we all had no lasting pain (except perhaps for his psychological pain from seeing skaters coast past him from behind with skates on the ground on either side of him).
