On several occasions, the Queen or her staff have been injured by the corgis. In 1954, the Royal Clockwinder, Leonard Hubbard, was bitten by Susan[30] upon entering the nursery at the Royal Lodge, Windsor.[31] Later in the same year, one of the Queen Mother's corgis bit a policeman on guard duty in London.[32]

In 1968, Peter Doig called for the royal staff to put up a "Beware of the dog" sign at Balmoral after one of the corgis bit the postman.[33] In February 1989, it was reported that the royal family had hired an animal psychologist to tame the dogs after they developed a habit of nipping them and the staff.[34] "And in 1989, the Queen Mother’s dog, Ranger, led a pack of corgis that attacked and killed the Queen’s beloved dorgi, Chipper."[35] In March 1991, the Queen was bitten after trying to break up a fight between ten or so of her corgis. She had to have three stitches to her left hand. John Collins, the Queen Mother's chauffeur, had to have a tetanus injection after he also tried to intervene.[36] In 2003, Pharos, a tenth-generation offspring of Susan, was put down after being mauled by Princess Anne's English bull terrier Dottie. Anne arrived at Sandringham to visit her mother for Christmas and the corgis rushed out of the front door as they arrived. It was reported that "Dottie went for Pharos, savaging the corgi's hind legs and breaking one in three places."[37]
