Prince William & Kate Middleton Mourn Death of Their Dog Lupo — See Their Heartbreaking Message

The Duke and Duchess of Cambridge posted a heartbreaking message on their official Instagram page announcing their dog Lupo's sad passing.

Prince William and Kate Middleton have lost their dog, an English Cocker Spaniel named Lupo. The royal couple announced Lupo's passing on their Instagram page on Sunday, writing:

"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."

Accompanying the heartbreaking post was a picture of Lupo, who Kate's parents Michael and Carole Middleton owned before presenting it to the royal couple as an early Christmas gift in 2011. Fans commented on William and Kate's post with condolence messages. One fan wrote:

"So sorry. Losing a beloved family dog is so hard for all. Remember the beautiful life you gave him, and in term he gave you."

Another fan thanked William and Kate for giving them a chance to get to know Lupo, adding that the dog would be dearly missed, while a third recalled when the late dog was a pup, adding that dogs mean so much to their families.

Lupo made many sweet memories with his family. The dog helped choose Prince George's name and made multiple appearances on William and Kate's official portraits, including one the Royal couple took after Prince George's birth.

With the yuletide season approaching quickly, the family is stepping up with their preparations, and the kids cannot wait for Christmas.

Lupo's death comes as a setback for William and Kate, who have been busy reaching out to charities as England continues to battle with the novel coronavirus pandemic.

One way they have been doing this is via video calls, and in one such video call held on Saturday, the royal couple held a virtual meeting with the London-based charity "Future Men."

In that meeting, William and Kate met two adorable babies belonging to Peter and Graeme, who became fathers for the first time. Peter and Graeme were two of the four men the Duke and Duchess spoke to in their meeting with "Future Men."

Like many other men, the first time fathers have benefited immensely from "Future Men's" vital guidance. The charity supports 500 fathers and their partners every year and gives them a safe space to speak about their concerns and worries as they grow into their roles as fathers.

When William and Kate are not busy with their official royal duties, they are parents to their three children, Prince George, 7, Princess Charlotte, 5, and Prince Louis, 2.

With the yuletide season approaching quickly, the family is stepping up with their preparations, and the kids cannot wait for Christmas, which is their favorite time of the year.

Louis, Charlotte, and George are so excited for the Christmas season that they have already penned their letters to Santa and continually nag their parents to put up the Christmas tree, a royal source has revealed.

The Duke and Duchess of Cambridge and their kids look set for a great Christmas, although they will have Lupo missing from the celebrations this year. May the adorable dog's soul rest in peace.
