Queen Elizabeth II is mourning the death of one of her beloved pet dogs. Holly, a Corgi, was reportedly put down last week (ends07Oct16), while the British royal, 90, was staying at her residence in Balmoral, Scotland. The dog, which famously appeared with the Queen on the cover of Vanity Fair earlier this year (16), had been suffering from an undisclosed illness. She was 13, the same age as the royal's three other furry friends, Candy, Willow, and Vulcan.
