Derby the dog showed how it's done Saturday at the Dog Surfing Championship at Linda Mar Beach in Pacifica, California.
Derby was decked out in shades and a life vest as he shot the curl. The waves were only moderately gnarly, but hey ... they're dogs so it's super impressive.
Check out the photo gallery ... a lab, a golden retriever, a pug, a terrier and garden variety mutts tried their paws at hanging 10.
There were different weight classes -- small, medium, large and very large. And get this ... there was even a tandem dog competition. One clearly rode bitch. And there was a human/dog pairing, too.
It was all for a good cause ... proceeds from the event go to dog-related charities. The sponsors include Banfield Pet Hospital, Camp Bow Wow, WAG Hotels, Pet Food Express, Woodrow Wear and Hanks Dog Stuff.
