Lost Dog Found Near Northpoint Mall, GA

Found at loading dock of office bldg near Northpoint Mall in Alpharetta Georgia (fulton county). Was confirmed to have been there as early as 6 am sat 10/12 by crane workers at location. Confirmed chipped. Connected with breeder who chipped him. She is out of town but hopes to have access to her records this upcoming sun 10/20. She feels confident her records are complete and she will be able to confirm who she sold this pup to. Hoping I can connect to owner this week or once breeder able to help me locate that person. If this does not happen, I will have to rehome him. Any assistance finding owner who may be looking for him would be so appreciated. Pictures please to confirm.
