The 11-year-old adorable pooch won the talent competition in 2012 alongside his owner Ashleigh Butler when the pair captured the nation's hearts with their talented dance routine, but on Friday (21.07.17) night, Ashleigh took to her Instagram account to announce the heart-breaking news that Pudsey had passed away.

Posting a collection of photos of the pair together, Ashleigh wrote: "I can't honestly believe I am writing these words. My handsome man has gone, and I don't know what to do without him.

"My heart is broken, and I don't know how I'm going to get through this. It hurts so much, that my handsome, incredible Pudsey Bear will never be by my side, where he belongs, again.

"We only had 11 years together, but they were the best years ever. He was my one in a billion dog that will never be replaced.

"I don't need to write all of his endless accomplishments on here to prove how incredible he was for me.

"Sleep tight my handsome man, I love you lots xxxx (sic)"

Ashleigh's mother Penny added her own tribute to the late dog on her Facebook account, where she said Pudsey had been battling "acute leukaemia".

She wrote: "We, as a family, had to make the hardest decision yesterday to let Pudsey go to sleep. We are absolutely devastated and in shock with how quick this has all happened, and our hearts are broken.

"We would have done anything to keep him with us, even for a little longer, but he didn't have any more time as acute leukemia made us take the heart breaking decision to end his pain.

"We so wanted to bring him home to the place where he was born and lived his whole life, but he was too ill to make the journey home from Davies vets. All five of us were with him when we said goodbye, and he was looking into Ashleigh's eyes as he went.

"This is going to take us forever to get over, as he meant everything to us. We just can't believe we won't see his big brown eyes again.

"Night night, Pud Pud. You gave us everything and wanted so little in return, just to be loved by Ashleigh and to spend your time doing the things you loved - agility, dancing and showing off.

"You were our special boy, and truly a dog of a lifetime. Sleep tight little man. Come and rest your head on our legs once in a while."
