People, clear your calendars of absolutely anything you have scheduled for Saturday, August 5. The World Dog Surfing Championships, a swell event where hounds will hang ten while chasing after the 2017 world dog surfing title, is set for all day Saturday in Pacifica. Held annually on the shores of Linda Mar Beach, the 2017 World Dog Championships are free to attend and watch, though there is an entry fee for competing dogs.

Just look at these good dogs surf in the above video from last year’s inaugural World Dog Surfing Championships. While admission to the event is free, there is a $25 entry fee for dogs hoping to compete in their weight class (Small, Medium, Large, or Very Large). There is also a Tandem Dogs Surfing Heat for multiple dogs on one board, and a Tandem Human/Dog Surfing Heat, plus a Dog Disc Ball-and-Fetch-Water Competition with a $10 entry fee and a Dog Fashion Contest which is free to enter.

“Humans without Dog not allowed to enter Surfing Competition,” warns the rules page of the World Dog Surfing Championships.

Last year’s winner was Abbie Girl, an Australian Kelpie rescue pup from the Humane Society of Silicon Valley who holds a Guinness World Record and is of course on Twitter. “Abbie and I have been surfing together for about nine years,” Abbie’s human Michael Uy tells NBC Bay Area. “When I went swimming, she followed me out into the ocean. I put her on the surfboard to see what she would do, and she stood up.”

If your dog does not know how to surf, the website of a therapy dog named Surf Dog Ricochet has some tips for teaching your dog to surf.

Proceeds from these dog surfing events go to various dog, surfing and environmental non-profits. Saturday’s event will benefit the Peninsula Humane Society and SPCA and Rocket Dog Rescue.

The World Dog Surfing Championships are Saturday, August 5 from 9 a.m. – 2 p.m. at Linda Mar Beach in Pacifica. A post-event Yappy Hour is scheduled to last until 5 p.m.
