A Louisiana Labrador named Zoey has broken the Guinness world record by having 5-inch-long tongue. Her owners always thought she had an abnormally large tongue but they didn't think it world-breaking until they went to the vet last year. A dog from Arizona previously held the record with a 3.74 inch tognue. Zoey's owners say they always have to warn people about her tongue because she'll slobber all over them. See some pics and video below.
