Found Dog

Found this dog by my work off Richards Boulevard and 160, kind of by the levee area. It was in our shop gate area, and a coworker ended up taking it home because we both felt bad for it, and my coworker has a big heart. It's a nice dog, hopefully we can find the owner soon, don't know how long my coworker can keep him. Any help appreciated Work zip code is 95811 off Richards Boulevard and levee area next to bike trail
