Dogs on Pismo State Beach San Luis Obispo County on California’s Central Coast is as mellow for dogs as it is for humans. But while there are lots of off-leash dog parks and play areas in the vicinity of SLO town, there are just a couple of places in the sand-and-sea department where Dottie can frolic off-leash (provided, of course, she is socialized to the max, has an ultra-reliable recall and can be trusted not to steal beach-goers socks or picnic goodies).
