Royal protocol prevents Prince William and Catherine kissing in public but the same rules don't apply to the couple's puppy Lupo.
William wasn't shy in showing his affection for the black cocker spaniel at a polo game on Sunday, scooping him up and kissing him repeatedly during a break in play.
But while William might not be tactile with Catherine in public, she told a group of school children that he spoils her rotten in private.
"William is very sweet and kind of spoils me," the Duchess of Cambridge told kids during a royal visit on Saturday.
William scooped up Lupo and covered him with kisses.
