Holly and Willow have been the Queen's companions for 12 years and they're likely to be the last of her Royal Majesty's pets.
The Queen is ending her corgi breeding program, bringing to a close a life-long love of the breed, according to an article in Vanity Fair.
The story - 'Queen Elizabeth and Her Corgis: A Love Story' - stated the Queen had "personally overseen a program of corgi breeding that is based on the grounds of Windsor Castle" since the 1950s.
"Purebred puppies from her kennel are registered under the affix of Windsor," it stated.
But Corgis have had a much longer history with the Royal family.
King George VI introduced Corgis to the Royal family in 1933 when he bought home a Corgi called Dookie from a local kennel.
The 12-year-old pair, Holly and Willow, are reaching the end of the breed's average lifespan. It's reported the 89-year-old Monarch does want to leave her beloved pets behind.
The royal corgis accompany the Queen almost everywhere. They tag along the Queen's visits around the UK and overseas, travelling with her in limousines, private planes and helicopters.
Hollow and Willow are 14th generation descendants from Susan, a corgi gifted to the Queen on her eighteenth birthday.
