Harbor, a black and tan coonhound from Pueblo, Colorado, was awarded the title of the 'longest ears of any living dog' by the Guinness World Records. His ears measure 12.25 inches for the left ear and 13.5 inches for the right (video below).
His owner Jennifer Wert says that when he was a puppy, Harbor would trip on his ears and roll down stairs. Wert added that people often stop them to ask questions, take photos or tug on his ears.
Tigger, a bloodhound from Illinois who died in 2009, still holds the record for longest ears ever. One was 13.5 inches long, the other 13.75 inches long.
