Queen ELizabeth has lost one of her last two remaining dogs just weeks before Christmas.
Loyal companion Vulcan, a dachshund-corgi cross, died a few weeks ago at Windsor, according to sources, reports The Daily Mail.
It is not known how old the Dorgi was, or what he died of.
But he had been the Queen's loyal pet since at least 2007, making him more than 13 years old - a good age for the breed.
Sources said the loss of her faithful companion was a blow to the 94-year-old monarch and has left her with just one remaining animal, Candy, also a Dorgi.
Her loss also comes ahead of what might be the Queen's loneliest ever Christmas.
The monarch and the Duke of Edinburgh, 99, are set to forgo the festivities spend the day 'quietly' at Windsor Castle - without forming a bubble with two other households.
The source said: "Her Majesty adores her dogs and it's always a blow, particularly now."
The Queen has always been synonymous with pets, particularly her Corgis.
The Queen has always looked after her own dogs as much as possible, and has a way with them that few have ever mastered.
They live in her private apartments at Windsor and Buckingham Palace, travelling with her to Sandringham as well as Scotland on a private jet .
She always tries to feed them herself , mixing their feed with a spoon and fork, from ingredients brought on a tray by a footman.
And even now she still likes to walk them herself.
The Duke of York once said his mother's love of her dogs has helped to keep her fit in old age.
'She is just amazing at her age and she walks a long way, the dogs keep her active,' Prince Andrew said.
