Queen Elizabeth II with one of her corgis at Sandringham, 1970. Corgis can be vicious. Over the years, the queen's corgis have nipped the royal clockwinder, torn the seat out of an officer's trousers and even bitten her majesty. In 1989, one of the Queen Mother's corgis killed the Queen's dog, Chipper. (Hulton Archive/Getty Images)
