Queen Elizabeth last-living corgi has passed away

Queen Elizabeth's last living corgi has died.

According to reports, the queen's 14-year-old dog, Willow, was put to sleep after a battle with cancer. After owning more than 30 corgis over the last 70 years, it marks the first time the queen has been without the breed since World War II.

She's taking the loss "extremely hard," explained insiders.

While Buckingham Palace hasn't yet commented on Willow's death, a source explained to The Daily Mail, "She has mourned every one of her corgis over the years, but she has been more upset about Willow’s death than any of them.

The source explained, "It is probably because Willow was the last link to her parents and a pastime that goes back to her own childhood. It really does feel like the end of an era."

Queen Elizabeth's love for the breed began with her first dog Susan, a gift to her for her 18th birthday by her father King George VI. Susan even traveled with Elizabeth and Philip on their honeymoon to Scotland in 1947, and thus began a long line of royal breeding by the queen for 14 generations.

The pups were so beloved by the family that they were included in a short movie with Daniel Craig for the 2012 Olympic Games in London. The queen also included her dogs in the palace's official portrait to mark her 90th birthday, which was shot by Annie Leibowitz.

Queen Elizabeth stopped breading the dogs in 2015 because she reportedly did not "want to leave any behind" when she passes.However, the queen still does have two other dogs -- dorgis, a mix between corgis and dachshunds.
