Blue Peter presenters are mourning the loss of another of the BBC show's dogs, with the death of long-serving Mabel who enjoyed a 14-year screen career.
It comes barely a month after the death of her canine co-star Lucy.
Border collie cross Mabel, seen by millions of children during her time on the show, was the programme's first rescue dog.
The popular pet, who retired last year, was the second-longest serving dog on the BBC show after Petra, who appeared on the programme for 15 years from 1962 to 1977.
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. She'll be sorely missed by the presenters and viewers alike."
Mabel originally featured on the programme in January 1996 when then presenter Katy Hill met her while making a film about the RSPCA.
She officially joined a month later when she came into the studio with inspector Mark Buggie from the animal charity. Her name came from the letters MAB1 which were written on her RSPCA kennel.
Mabel - whose exact age is not known, but was thought to be 16 - starred alongside 14 different presenters in hundreds of studio shows.
She was notable for her different coloured eyes - one brown, one blue - and a folded-over ear. Mabel spent her retirement living with a former member of the production team.
