Before Guri Bosch, a 3-year-old labrador retriever, won the Canine Division of the 5-mile crossing of Lake Willoughby in Vermont in 2013, there was Manaia.

Manaia was a 5-year-old Labrador-Irish setter that defeated 200 of the 613 humans in the 1980 Waikiki Roughwater Swim, completing the 2.4-mile swim in 90 minutes.
