The Queen, 89, feeds them specially designed meals depending on their needs – and they are all served on silver platters. For their part, the dogs are content to wait their turn as they are handed their meals in order of seniority.
Animal behaviorist and corgi trainer Dr. Roger Mugford says he has witnessed feeding time at the palace.
"Each dog had an individually designed menu, including an array of homeopathic and herbal remedies," he told the spring issue of the U.K.'s Town & Country magazine. "Their food was served by a butler in an eclectic collection of battered silver and porcelain dishes.
"As I watched, the Queen got the corgis to sit in a semi-circle around her, and then fed them one by one, in order of seniority. The others just sat and patiently waited their turn."

She also can't abide "unkindness" to pets, taking a "very dim view of President Lyndon B. Johnson picking up his dogs by their ears," Mugford added.
The Queen, who is believed to have owned dozens of corgis in her lifetime, currently has two, Williow and Holly. She also owns two dachshund-corgi crosses (known as dorgis), named Candy and Vulcan.
One famous pet, Monty, was among those that trotted alongside her as she walked the palace corridor with James Bond's Daniel Craig in the London 2012 Olympics opening ceremony mini-movie. Monty died soon after the Games.
"When she's talking about her dogs or her horses you see a completely different side to her: she relaxes," Mugford added. "Dogs are great levellers, and they're not influenced by social status, which must be a great relief to her. No wonder she enjoys being around them."
