The Queen is said to be “devastated” after the death of one of her pups given to her when Prince Philip was sick.
Fergus, the dorgi puppy, was given to her during the time the late prince was in hospital and being treated for his illness.
However, it has been reported that the puppy has since died over the weekend, aged only five months.
The Dachshund Corgi Crosses were a surprise gift from their son, Prince Andrew, in February.
A Windsor Castle insider said: “The Queen is absolutely devastated.
“The pups were brought in to cheer them up at a very difficult time.
“Everyone involved is upset that this will come so soon after she lost her husband.
“There were also problems with your grandson Harry.”
The Queen was believed to have given up owning new pets after her Corgi Vulcan died last October. Insiders said they feared they might trip over, reports The sun.
Fergus was named after the Queen’s uncle, Cpt Fergus Bowes-Lyon. He died in 1915 at the age of 26 when he led an attack on German lines at the Battle of Loos, France, during World War I.
The Queen stays with Muick – pronounced Mick and named after a beauty spot in Balmoral, Scotland – and older Dorgi Candy.
Buckingham Palace made no comment.
