Prince William and Princess Catherine marked a special milestone today as they shared a new picture of a beloved family member that's only been seen once before. The Prince and Princess of Wales shared a new photograph of their puppy, Otto, who turns one today. Otto is Orla's son, from the litter she gave birth to last year and who the Waleses kept.

Alongside the picture, Catherine and William wrote: "Welcome to the family, Otto! 1 today." Last year, the English Cocker Spaniel reportedly gave birth to four puppies, bringing much joy to the Wales household, after a difficult few months, following Catherine's cancer diagnosis and treatment.

The prince and princess's three children, Prince George, Princess Charlotte and Prince Louis, were said to have fallen head over heels with the new pups, who filled their-then home, Adelaide Cottage, with a joyous patter of tiny paws.

The pups' father's identity was never revealed.

Orla featured in Princess Kate's emotional video in September 2024 when she revealed that her cancer treatment was over.

The couple are believed to have welcomed her into their family in 2020, the same year their beloved dog, Lupo, died.

The sweet dog was a puppy from one of Kate's brother's dogs, and James Middleton is known for being a big dog lover.

William was seen being surrounded by three new puppies and his dog, Orla in the photograph released by Kensington Palace to mark his 43rd birthday last year.

The picture, taken by the Princess of Wales, was shared on social media with the caption: "Happy birthday! Love C, G, C, L, Orla and the puppies!"
