Scafell Pike is England’s highest peak, standing at 978 meters (3,209 ft) above sea level.
Center manager Anna O’Donnell said: “The couple who discovered Scafell said he was terrified and nervous and it took them about half-an-hour to wheedle him over to them.
“They informed they did try to get help in England and had called the local police but they hadn’t been able to help so they took Scafell home because they were so concerned about him, and then called us.
“Unfortunately Scafell isn’t microchipped so we have not been able to trace his real owner.
“We have also looked for information about dogs that have gone missing in the neighborhood without any trace.”
It is not known how the dog ended up at the top of the mountain.
Miss O’Donnell said: “At this period it’s all a bit of a mystery but we assume Scafell may have been taken up the mountain by his owner and become lost. There is also the possibility he was deserted and made his own way up to the top of Scafell Pike.
“It would be tremendous 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.
