A dog rides a wave while competing in the Surf City Surf Dog competition on Sept. 29 in Huntington Beach, Calif.

Now in its fifth year, the canine surfing event invites pups of all sizes to "hang 20" and try their luck on some of California's gnarliest waves. Huntington Beach also happens to be the site of the U.S. Open of Surfing, a weeklong event that is the largest surfing competition in the world.
