Guinness World Records announced a Colorado coonhound will appear in the 2012 book after receiving the title of "longest ears on a living dog."

The record keeping organization said Harbor, an 8-year-old coonhound belonging to Jennifer Wert of Boulder, made it into the book with a left ear measuring 12.25 inches long and a right ear measuring 13.75 inches long, The Denver Post reported Tuesday.

"When he was 9 months old, he was sitting in his crate and his ears were hanging down over his paws," Wert said.

Guinness said the previous record holder was an Illinois bloodhound named Tigger, which had a 13.5-inch left ear and a 13.75-inch right ear before his death in 2009.
