A thermal imaging drone helped rescue a dog in dramatic circumstances - after she had spent five days trapped down the hole of a mountain.

The RSPCA, fire service, police and volunteers joined the hunt to find a Chihuahua, named Cherry.

The dog went missing on March 15 while walking on Mynydd James in the Welsh Valleys mountain range.

Her owners launched a Facebook campaign to try to find her and local people donated over £1,000 to help in the hunt.

People searching for Cherry heard the sounds of a dog barking on the mountain on March 19 and the following day an unmanned drone fitted with therman imaging camera located her.

Cherry was found trapped down a mountain hole, with an RSPCA grasper used to help bring her to safety and she was returned to her owners.

She has now been checked over by a vet, and - though very tired - is doing well, after the remarkable ordeal.

RSPCA inspector Izzi Hignell, who worked on the rescue, said: "We are so relieved that Cherry has been found safe and well, and is now back with her family.

"This was a truly remarkable rescue effort, which shows the strength of feeling across the community towards animals, and the importance people attach to keeping them safe.

"Cherry was located down a mountain hole using a thermal imaging camera, and then - thankfully - it was possible to rescue her using a grasper device.

"We worked with so many agencies to help Cherry, and the public response to the campaign to find her was heartening.

"It was an incredible experience to be involved in, and amazing to play a part in such a happy ending."

Cherry's owner Katinka Slingsby said: "The rescue was absolutely incredible, and we are so overwhelmed by the levels of support from agencies and the public.

"We are so grateful to everyone involved. Animals are my life, and it means the world to have Cherry safely back with us.

"Fortunately, whilst Cherry has lost a little weight and is exceptionally tired, she is doing so well."

Drone pilot Lucy Morgan and camera operator Daniel Veg, who work for Resource Group Unmanned Aviation Services, took part in the rescue.

John Larkin, from the Worcester-based company, added: "We are delighted to have been able to reunite Cherry with her owner.

"Using thermal imaging cameras mounted to one of our unmanned aircraft, we were able to locate Cherry within 20 minutes.

"This just goes to show the widespread applications of drone technology from aerial inspection and surveying to search and rescue situations."
