The ghost of Queen Elizabeth II makes her corgis bark, according to Sarah Ferguson.

The Duchess of York adopted the dogs, called Sandy and Muick, following the monarch’s death in September.

“And I always think that when they bark at nothing, and there’s no squirrels in sight, I believe it’s because the Queen is passing by,” the romance novelist said during promotion for her new historical fiction book, “A Most Intriguing Lady.”

The animals were a gift to the queen from Ferguson and her ex-husband, Prince Andrew. Ferguson has staunchly defended Andrew as “a good man” amid the controversy over his friendship with convicted sex offender Jeffrey Epstein.

The couple divorced in 1996 but still live together at the Royal Lodge in Windsor, where she continues to walk the late monarch’s dogs.
