A police breeding dog who became a web sensation by mothering its newborn pups live on the internet has retired from the force.
German Shepherd Heidi has bred 28 puppies in three litters for Northumbria Police, the majority of which have gone on to be working dogs.
A spokesman for the force said: "Heidi has retired from Northumbria Police after more than five years of faithful service.
"The average number of litters produced by a police breeding dog is one to two, so for her to have had three is quite unusual."
Heidi, who was born in July 2004, lives in Northumberland with her owner Rachel Willis, one of the force's kennel attendants.
Ms Willis said: "She has had three litters of puppies over the years - two litters of nine pups and one litter of 10. She has always been a fabulous mother and takes excellent care of them all, making things so much easier for us."
Heidi was watched by thousands of people over the internet when she had her last litter of puppies in October 2009.
Northumbria Police set up a webcam so people could follow Heidi and the puppies during their first few weeks together.
The Puppy Watch page was viewed more than 320,000 times by people from as far afield as Papua New Guinea, Brazil, China, Peru, Russia and Iran.
Ms Willis added: "Things will not change too much for Heidi now that she has retired as she will continue living at home with me. Having had three big litters she has certainly done her bit for the dog section."
