In the first photo, Bindi is seen casting an affectionate gaze towards Chandler, while cradling her Cavalier King Charles Spaniel, which is looking at the couple with puppy-dog eyes.
A follow-up snap shows the sprightly pup running and leaping in the air while playing in the garden with its new adopted parents.
Chandler later shared the news on his own personal Instagram, writing: “Welcoming our newest and cutest family member.
“Introducing Piggy our gorgeous puppy. Can’t wait to begin the new decade giving this sweetheart the happiest and most loving home. 2020 here we come!”

Another person stated: “Aw... love my Cav King Charles Spaniel... a more loving dog you will not find!!! Blessings on you three this year and decade!! Thank you for all you do!!”
