Dozens of dogs -- and more than 1,000 people -- showed up for the second annual World Dog Surfing Championships Saturday in Pacifica.
Dog surfing is relatively new -- the first competition was in San Diego 12 years ago.
And while the event might seem silly, competitive dog surfing is growing quickly, with contests in Hawaii, Florida, Texas and as far away as Australia.
Dogs compete solo, just dog and board, or tandem, with either a person or with another dog.
The dogs are scored by three judges.
