Pucker up! In a bizarre competition in the US, dogs and owners locked lips at the annual Valentine's Day canine kissing contest, with the winning pair smooching for 45 seconds straight.

Beau, a humble-looking 12-year-old Yorkie and dachshund mix, was crowned the winner and still champion of the 9th Valentine's Day Canine Kissing Contest and Cocktail Party at the Planet Dog Company Store in Portland.

Beau's winning, unbroken smooch with owner Linda Walton of Saco lasted 45.8 seconds. It was a little off the pace of nearly a minute he set last year.
