This year, the prize -- a $75 gift certificate to Planet Dog -- went to Beau, a 12-year-old Yorkie and dachshund mix, and his owner, Linda Walton. The victorious snog went on for 45.8 seconds. The pair won last year, too, according to the Bangor Daily News, clocking in at just under a minute.

Walton opted to share her winnings with the second and third-place winners.

While there's an old adage that a dog's mouth is cleaner than a human's, this is probably a myth, according to Dr. Harold Katz. Even so, there's typically not much danger in letting your canine companion giving you a big slobbery kiss now and then.
