Beau’s winning, unbroken smooch with owner Linda Walton of Saco lasted 45.8 seconds, Bangor Daily News reported.
It was a little off the pace of nearly a minute he set last year, but still good enough to lick the competition.
Second place went to Sunny, a Staffordshire terrier, and owner Casey Mountain with a time of 16.8 seconds.
Third was lapped up by a dog named Django and owner Erik Boucher, who locked lips for 11.7 seconds.
For their winning effort, Walton and Beau were awarded a 75-dollars gift certificate to the Planet Dog store.
Walton donated most of her winnings to the runners-up.
