An animal welfare group is trying to solve the mystery of how a dog came to be alone top of England's highest peak.
The male collie cross was discovered by hikers wandering on the summit of Scafell Pike in Cumbria on Saturday.
Two holidaymakers found the dog, believed to be aged between five and eight.
The couple tried to get help in England but were unsuccessful, so they took him home to Maybole, South Ayrshire, before alerting the SPCA.
Rescuers said it was still a "mystery" how the dog came to be on top of the mountain.
It is not known whether he was abandoned or just became separated from his owner.
The dog is now being cared for at the charity's animal rescue and rehoming centre in Glasgow, where staff have nicknamed him Scafell.
Centre manager Anna O'Donnell said: "The couple who found Scafell said he was petrified and nervous and it took them around half-an-hour to coax him over to them.
"They advised they did try and get help in England and had called the police but they hadn't been able to assist so they took Scafell home because they were so worried about him, and then called us.
"Unfortunately Scafell isn't microchipped so we have been unable to trace his owner.
"We have also searched for information about dogs who have gone missing in the area with no luck."
It is not known how the dog ended up at the top of the mountain.
Miss O'Donnell said: "At this stage it's all a bit of a mystery but we believe Scafell may have been taken up the mountain by his owner and become lost. There is also a chance he was abandoned and made his own way up to the top of Scafell Pike.
"It would be fantastic if we are able to reunite him with his owner if he has gone missing. If not we will find him a loving new home in Scotland."
Anyone who recognises Scafell is being urged to contact the Scottish SPCA's Glasgow centre on 03000 999 999.
