The Surf Dog Surf-A-Thon, which is normally held every September at Del Mar Dog Beach in Del Mar, was held virtually this year, with the owners of surfing dogs around the world submitting videos of their pets' prowess.  Dogs were divided by weight class and judged on the duration of the ride, the size of the wave and special tricks -- including walking on the board and barking.  Even seen a dog on a surf board?  Check this out!
