Yesterday we found a nice hiking spot called Pulgas Ridge Open Space Preserve in San Carlos. Within the park, it has a big area where dogs are allowed off-leash (though not fenced). We were a bit worried at the beginning, but Maya did surprising well. She would run a few yards ahead or lag a few yards behind, but she never went far. We were lucky that she didn't see any wild animals, other dogs or human while off-leash, or it might be a different story. Next time we'll probably bring some yummy treats with us just in case.
