The Royal couple announced the sad news on Instagram on Sunday, Nov. 22. They shared a photo of the black cocker spaniel and wrote, “Very sadly last weekend our dear dog, Lupo, passed away. He has been at the heart of our family for the past nine years and we will miss him so much. – W & C.”
Lupo was part of a litter born in 2011 to Ella, the dog of Kate’s parents Carole Middleton and Michael Middleton. Kate and William welcomed the puppy to their Kensington Palace home that Christmas, eight months after their royal wedding. Lupo was so popular that in 2014, he became the subject of a children’s book.
