Blue Peter dog Mabel has died, after 14 years as a TV star.
Border collie cross Mabel retired last year from the show and was their second-longest serving dog.
Presenter Helen Skelton said: "I'm proud to have worked alongside such an iconic Blue Peter dog. She was dearly loved and that's a credit to her quirky character."
Mabel was the show's first rescue dog. Her age isn't known, but it's thought to have been 16.
She appeared on the programme in a feature about the animal charity RSPCA, but a month later joined the Blue Peter team.
Mabel's name came from the letters MAB1 which were written on her RSPCA kennel.
She was well known for her different coloured eyes - one brown, one blue - and a folded-over ear.
The sad news comes a month after the death Mabel's canine co-star, Lucy.
