Take a look at the top five record-holding dogs along with some of their U.S. Olympic counterparts in each category - could a canine competition become an official part of the International Games in the future? Stranger things have happened! On your mark, get set ... go!
Natural born swimmer Umbra, a Labrador/Greyhound mix, has earned a historic four events with The Guinness Book of World Records. She's logged well over 600 miles in tandem swimming, even joining a polar bear for a New Year's Day dip in the lake. Her best unofficial record is a whopping 5.5 miles in just 2 hours and 40 minutes. The U.S. Olympic team has their own swimming icon as well with Michael Phelps, who was named World Swimmer of the Year in 2003, 2004, 2006 and 2007. Phelps took home eight medals (including six Golds!) at the 2004 Summer Olympics in Athens, tying the world record for the most medals at a single World Games. Surely, all eyes will be on Phelps this summer in Beijing to see what he'll do next - perhaps Umbra would make the perfect poolside cheerleader?
