(Portland, OR)  --  A Portland dog is back together with her owner.  A homeless man who allegedly stole Roxi the black lab dropped her off at an office yesterday.  Roxi was stolen from outside the Good Earth Cafe on Southwest 3rd Avenue near the Justice Center.  Roci's owner, Sam Buck, says he's not looking to track down the homeless man who stole his dog; he's just glad to have her back.
