By Emma Innes PUBLISHED: 09:16 EST, 14 February 2014 | UPDATED: 11:33 EST, 14 February 2014 A young boy has credited his pet Labrador with protecting him for a crippling condition that affects his nervous system. Brad Oliver has a rare disorder which means his heart races every time he stands up or becomes excited – this alters the blood supply to his brain, causing him to pass out. But, three-year-old Fudge, a golden Labrador, instinctively knows when Brad is about to fall ill and has kept him out of harm’s way on countless occasions.
