Documentary of the Day: Dogs Riding in Sidecars with Bikers

Everyone knows dogs love to stick their furry faces out car windows, letting their slobbery tongues and ears flap freely on the open road.

But did you know they also love motorcycles?

A new film called "Sit Stay Ride," from husband-wife filmmakers Eric and Geneva Ristau, tells the story of 18 bikers and their 15 badass canine copilots.

The documentary was funded in large part through a Kickstarter campaign, and it is now available on DVD and Vimeo on Demand, with a portion of the proceeds going to the American Humane Society and other animal charities.
