The canines took part in the "2013 Loews Surf Dog Competition - Unleashed by Petco."
YouTube sensation Tillman also showed up to the 8th-annual competition. The English bulldog from Huntington Beach is usually on his skateboard, but he ditched it to show off his surfing skills. Tillman won first place in the large dog category.
Dogs weren't the only ones having a good time. More than 3,000 people hit the sand for a little fun in the sun.
The event raised close to $20,000 for the American Society for the Prevention of Cruelty to Animals.
