Tributes have been paid to a long-serving police dog after she died peacefully. 

Police dog Patch helped keep people across Scotland safe through nine years of service on the force - and she was even a valuable team member in the 2014 Commonwealth Games in Glasgow. 

The springer spaniel retired in 2017 but before that, she was one of the most experienced bomb search dogs in Scotland. 

Her work even landed her with a Royal seal of approval from the Queen and an appearance on live television.

A Facebook post reads: "PD Patch was a much-loved and valued member of the Police Scotland family and her loyalty to the force and her handler knew no bounds.

"She was a great colleague and friend to many and well known throughout the country.

"Patch passed away peacefully in her sleep on Sunday night. The final selfless act from a truly selfless Police dog.

"We are all extremely proud of the fantastic crime-fighter she became."

Patch mainly worked in the North East and was a regularly in Royal Deeside as part of her security duties for members of the Royal Family. 

Accompanied by her handler PC Warden, she was also deployed at the 2012 Olympic Games in London.

Tributes poured in across social media and one user wrote: "I'm so sorry to hear this really sad news. Much love to Patch's family. Heaven gains another hero."
