Kate had nothing to worry about, however, as the recipient of the future King's kisses was the couple's cute Cocker Spaniel Lupo.
William, who turns 30 on June 21, couldn't resist a cuddle with the six-month old puppy after competing in a charity match on the final day of the Gloucestershire Festival of Polo, at the Beaufort Polo Club.
The Prince had been helping raise money for children's charities Well Child, Child Bereavement and Tusk Trust, a conservation charity he supports.
