I personally have never ice fished before but I am not quite sure why you would need a "highly-trained" canine to help you do so.
Two ice fishers who were very serious about their hobby were in the practice of throwing small bits of dynamite onto the ice to create holes and "stir up" fish. One day, they bought a highly-trained dog to help them fish. Then they went to the lake, lit the dynamite, and threw it onto the ice. The dog, however, had apparently been trained to fetch, and ran to the dynamite and picked it up in his mouth. Then he ran to return it to the fishermen. The fishermen managed to run away from the dog quickly enough to avoid getting blown up, but just barely.
