Capped twice for Scotland, Dunlop gained both his caps against England in 1971. He debuted in the Five Nations fixture at Twickenham, then played in the Centenary match a week later at Murrayfield, with Scotland winning each time. This gives him the unusual distinction of beating England twice in a week long Test career.[1]
Dunlop, a farmer by profession, founded free-range egg business Scotlay Eggs.[3]
