From the time Dan Wehunt wanted a dog, he wanted a German shorthaired pointer. A track and field teammate at the University of Florida had one, and whether it was the breed’s fashionable coat, eagerness to please or irresistibly friendly eyes and smile, Wehunt knew he had to have one.

After graduation, he found Odessa, the quietest in her litter, but the sweetest, too. He took her home and trained her with his twin brother. He didn’t know she’d grow up to be a world champion.
