Help Find Roxy: Missing Elderly Dog

Our dog Roxy ran out of our yard on Albany Way in Bedford Estates in South Fulton. She's very old and has been seemingly disoriented the last few weeks. She's not seeing or hearing very well and when I tried to get her to come in for water she started running down the hill. If you happen to see her can you please please message me. Pictures included. She is a gentle giant that raised our 4 babies but I already know people typically don't trust dogs they don't know. So please please reach out if you see her. We've had her for 14yrs and would really appreciate having her home.
