Waterfowlers wince when their Labs break to retrieve a downed mallard while another flock makes its final approach, or worse yet, lunge forward before any quarry is in range at all. That’s what makes steadiness so highly prized in gun dogs. There are many ways to develop a calm, focused retriever, but Duckhill Kennel’s Robert Milner has a method that is unique. Milner works his Labs in flight pens loaded with birds. While that method is unconventional in America, it’s commonplace in the UK for good reason: It works.
