August 1st in Imperial Beach the annual Unleashed by Petco Surf Dog Competition takes place near the pier. Get stoked! It's time for the most adorable surf event of the year. At the 2015 Unleashed by Petco Surf Dog Competition, the most fearless dogs will jump on their boards, paddle out and hang 20! This event must be seen to be believed.
