After 15 days of being lost, Guinness has been found!!! He turned up about a mile away from our home. He wandered into a home construction site and one of the workers was able to get Guinness to approach him. He then called me from his Collar ID tags. He has a few minor cuts and scrapes, he's very skinny but he is home eating well and resting. We are so happy to have him home. His fur sister nearly tackled him when we brought him back home. Thank you to everyone who kept an eye out for him. Our family is whole again.
