Kate Middleton With Prince William and Lupo at Polo Fields

Kate Middleton brought her dog Lupo along to watch Prince William play polo at the Beaufort Polo Club in the UK today. William picked up the dog and gave him a kiss when he was finished with his match. Kate and Lupo played with a friend's child when Kate wasn't busy chatting with Harry and William's cousin Zara Phillips and her husband Mike Tindall.

It was the second day of the sport for William, who also participated in a charity game with his brother, Prince Harry, yesterday. Kate's had a busy weekend herself, kicking things off on Friday at a performance of The Lion, the Witch, and the Wardrobe. She made another public appearance alongside the royal family at the Trooping the Colour ceremony Saturday morning and earlier today met up with a group of children at a camp.
