On opening weekend of dove season, my 2-year-old Lab, Minnie, got a crash course in field retrieving. I’ll admit, my son, Jack, and I weren’t so sure about this dog. Last year she was barely a year old. She mouthed the birds and especially had trouble with the young-of-the-year doves. Minnie was not fond of a muzzle full of feathers from juvenile birds that seem to shed like a poodle. She’d pick the bird up, drop it, spit out feathers, bring it 10 feet, drop it again. She loved looking for cripples, but bringing the birds to hand was not her strong suit. And she was the worst kind of steady to shot, meaning not really.
