Awards are handed out based on dog size (Small, Medium, Large/XL) as well as other categories, including Human/Dog Tandem. A 10-year-old rescue dog named Faith grabbed the top spot in the Large/XL group, while Skyler, an Australian cattle dog, nabbed first place as the Top Dog Final Overall Champ.
Though dog surfing is said to have started in the 1920s, it was first recorded circa 1932 in the silent film On the Waves at Waikiki, in which a man and his terrier named Night Hawk can be seen riding waves together in Hawaii on a wooden surfboard. The World Dog Surfing Championships has been held on the California coast since 2016, and it is one of several such contests that have been established around the world.
