With a stomach full of scrambled eggs, Jake dog-paddled his way into history, leaving most of the serious - and human - swimmers in his wake.
Organizers of the South End Rowing Club's 10th annual Alcatraz Invitational - a 1.2 mile swim from the infamous prison island to the San Francisco shoreline - say the 65-pound golden retriever is the first canine known to have made the crossing.
He was the only dog among more than 500 swimmers who lept into the chilly, choppy waters on Saturday, coming in 72nd overall. His time was 41 minutes and 45 seconds.
The crowd cheered as the 4-year-old pooch made his way onto solid ground, shaking sprays of water and dodging a woman who tried to put a medal around his neck.
