Queen Camilla is mourning the death of her rescue dog, Beth, who died over the weekend from an incurable tumor. Palace aides have described Camilla as “very sad indeed” following the loss of her beloved pet, who had to be put down due to the tumor. Queen Camilla adopted the Jack Russell terrier in 2011 when Beth was just three months old.

Queen Camilla and her husband King Charles III announced on Nov. 18 that their beloved rescue dog Beth had died.

Alongside a photo of the queen with her beloved rescue puppy, Beth, the family announced her death. “A sad farewell to Beth, The Queen’s much-loved companion from Battersea Dogs and Cats Home,” the statement began. According to People, Beth had an untreatable tumor, which resulted in her death.
