SJ Bark in the Park festival promises doggone good fun for attendees on two legs … or four

Diego, a whippet/border collie mix, runs at breakneck speed, jumping four barriers in a row, snatching a ball and triumphantly delivering it to his handler. He’s practicing for a demonstration at Bark in the Park, a dogfest happening Saturday in downtown San Jose.

The demonstration is one of many offerings at the event including an owner/dog look-alike contest, food and drink, kids’ activities and a tail-wagging contest. Bark in the Park is billed as the largest dog festival in the U.S., with over 15,000 dog lovers and 3,900 canines. It runs from 10 a.m.-5 p.m. Sept. 17 at William Street Park.
