Queen Elizabeth II may seem composed in public, but if her grandson is to be believed, the monarch likes a bit of ruckus in her private life.

In an upcoming ITV1 documentary on his grandmother, Prince William spills the dirt on the Queen’s beloved dogs, saying that they bark “all the time.”

“I don’t know how she copes with it, but her private life with her dogs and her riding and her walking, it’s very important to her,” he tells interviewer Alan Titchmarsh in Elizabeth: Queen, Wife, Mother, which airs in the U.K. June 1. “She has got to switch off.”

The Queen, who first fell in love with the Welsh Corgi breed as a child, currently has six dogs: three Corgis named Monty, Willow and Holly, and three Dorgis (Corgi-dachshund mixes) named Cider, Candy and Vulcan.

“She enjoys it,” William says. “I would just question the noise!”

The royal family members are famous for their love of animals, and Will is no exception. He shares a cocker spaniel puppy named Lupo with his wife Kate.
