How to find 2 dogs that were given up for adoption sometime around Sept 2007 in Sahuarita or Green Valley, AZ.?

If they were chipped, and you still have your paperwork, that'd be a place to start. Contact the chip company for last scan info. if available. If you knew which group took them in (e.g. AZ Chihuahua Rescue) they'd know because they track all fostered and adopted dogs. Good Luck
