Yesterday evening, Prince William and Kate Middleton’s official Instagram account shared some heartbreaking news. Their family dog, Lupo, passed away over the weekend.

“Very sadly last weekend our dear dog, Lupo, passed away,” the post started off, captioning a beautiful shot of their beloved Lupo. “He has been at the heart of our family for the past nine years and we will miss him so much. – W & C.”

Kate’s brother, James, also penned a tribute to Lupo who was part of his dog Ella’s litter. “Lupo was the son of Ella, brother to Zulu, Inka & Luna,” he shared. “Nothing can ever prepare you for the loss of a dog. For those who have never had a dog, it might be hard to understand the loss. However, for those who have loved a dog know the truth: a dog is not just a pet; it is a member of the family, a best friend, a loyal companion, a teacher and a therapist.”

“The pain I felt from loosing my first dog Tilly back in 2017 still hurts and on hearing the news about Lupo brought a wave of emotions flooding back,” he admits. “Rest in peace Lupo. Tilly & Mini will be waiting for you. You will always be remembered, and your legacy will live on forever. Good Boy.”
