Susan (20 February 1944 – 26 January 1959) was a Pembroke Corgi dog owned by Queen Elizabeth II that was given to her on her eighteenth birthday. Following the dog's death in 1959, the Queen personally designed a headstone for her grave at Sandringham House. Susan was the first of a long line of Corgis and Dorgis (Dachshund/Corgi crosses) owned by the Queen, all of them descended from Susan. The dogs often accompanied the Queen in her public appearances, and thus came to feature prominently in her public image.
