LOS ANGELES - More than 70 dogs and their owners took to the waves in California for the Helen Woodward Animal Center's 13th annual Surf Dog Surf-a-Thon. The event, sponsored by food maker Blue Buffalo, saw dozens of dogs competing in different weight classes to see which canine displaying the most wave-shredding skills - as well as "surf spirit" - at Dog Beach in Del Mar. The dogs rode waves in 10-minute heats and were judged by a panel of surfers and enthusiasts, who then went on to choose the "Best-In-Surf." The entire event was live-streamed on YouTube. The Surf-a-Thon raised funds for the Helen Woodward Animal Center, a dog and cat adoption organization in San Diego. - Agencies
