The black and tan male collie cross was picked up at the summit of Scafell Pike in the Lake District on May 16 by a couple of Scottish holidaymakers.
Staff at the Scottish SPCA in Glasgow nicknamed the dog Scafell and launched an appeal to locate the owner.
A Cumbrian sheep farmer has now come forward to claim the dog, who is actually named Sid.
Katrina Cavanagh of the Scottish SPCA, said: "The couple who found Sid told us he was petrified and they brought him home because they couldn't get help locally.

"The owner is a local sheep farmer and Sid is one of his working dogs. He believes Sid took off after a bitch in season and had been looking for him.
"While he was surprised when he found out Sid was in Scotland, he was also very relieved he was safe.
"He's a lovely dog and we wouldn't have had any trouble finding him a home if we'd needed to as we had lots of offers.
At 978 metres, Scafell Pike is the highest peak in England.
