When he returned upstairs, Byron found the noose clenched inside his dog's mouth. Geo, a six-year-old Rare Welsh Bull Mastiff, had grabbed the noose when Byron left the room and refused to give it back.
Byron was struck by how aggressive Geo was acting, growling and tearing the noose apart.
He believes it was his dog who sensed what he was planning to do, and he wasn't going to let it happen.
Geo saved Byron's life, and now Byron is working to save Geo's in return. Byron has set up an online fundraiser to help pay for Geo's medical treatment.
