State Dog Trainers Set Record

Two Wisconsin gun dog trainers wrote a first in the annals of the North American Versatile Hunting Dog Association recently when they qualified their two young German Wirehaired Pointer litter-mates in both The Natural Ability and Utility tests conducted by the Wisconsin chapter of NAVHDA recently near Dundee.

According to the test judges, no one in the U.S. or Canada ever before qualified the same dog in both the Natural Ability and Utility tests in the same weekend until Mike Duffy and Karson Korth, both of rural Clintonville, did it with their precocious Wirehairs, Rough N Ready Ober Jaeger and Wilhelm Fleck von Korth.

NAVHDA is a non-profit organization dedicated to fostering, improving and protecting the versatile hunting breeds in North America. It sponsors field tests for multi-purpose gun dogs that truly test their versatility in the field and marsh.

The Natural Ability test is for young dogs under 14 months of age and seeks indications of seven hereditary characteristics that indicate whether a dog has good potential and highlight traits being passed on in controlled breeding programs. They are: use of nose, search, water-love, pointing, tracking, desire to work and cooperation.

The Utility test is designed to display a welll-trained dog's usefulness to on-foot hunters in all phases of hunting both before and after the shot, the testing simulating actual hunting conditions in the uplands and in water. The test for a useful waterfowl retriever involves search for a duck, walking at heel, remaining by the blind and marked retrieve of a duck. In the field test, the dog is judged on search, pointing, steadiness to wing and shot, retrieve of a shot bird and tracking and retrieving a "drag" which may be a game bird or animal.

The 32-year old owner-trainer-handlers have been hunting together since high school. Korth is employed by Utility Tool and Body company of Clintonville. Duffy, an independent insurance agent, has trained dogs professionally on the west coast and with Orin Benson, famed pioneer retriever trainer from Eagle, Wis. and is the son of Dave Duffy, Wisconsin Sportsman's dog columnist.
