The royal family celebrated a significant milestone a few days ago – the 73rd wedding anniversary of Queen Elizabeth II and Prince Philip – but the week was also a sad setback. On Sunday, Prince William and Kate Middleton broke news that Lupo, the black English cocker spaniel they have owned for nine years, has died.

The couple, who are parents to Prince George, Princess Charlotte and Prince Louis, paid tribute to Lupo on their official royal Instagram page.

“He has been the heart of our family for nine years and we will miss him so much,” the headline reads.

The dog, whose name means “wolf” in Italian, entered the family in 2011, the year William and Kate were married. Occasionally, he also appeared in their family portraits, including the debut of Prince George, but was absent in recent images shared on social media.

No cause of death was mentioned for the dog, whose death sparked a flurry of condolences from royal watchers online. His death also follows the release of The Crown’s fourth season, which cuts deeply into the tumultuous marriage of William’s parents, Prince Charles and the late Princess Diana.
