PACIFICA, Calif. (AP) — Top dogs were riding waves Saturday at the annual World Dog Surfing Championships as hundreds of spectators cheered — and barked — from the Northern California beach. Sophia Sadlowski first put her Miniature Pinscher, Rusty, on her surfboard to capture fun photos when he was just a puppy. Small-, medium- and large- sized dogs competed in heats and then the highest scoring dogs in each heat faced off for the top prize. The day also included tandem contests, where multiple dogs, as well as dogs and humans, shared the surfboard. Sadlowski said Rusty was in his first surf competition at four months old, and she and her pup are now both cancer-free.
