According to an article on the BBC, Pero left the farm in Cockermouth, Cumbria on 8 April, only to show up on his previous owners’ doorstep on a farm near Aberystwyth in west Wales a fortnight later.
His previous owners, Alan and Shan James, have no idea how he found his way back.
Speaking to the BBC, Shan James said the family gave Pero to a farmer in Cumbria because the farmer was looking for a dog that could round sheep and follow a quad bike. So Pero started working on the farm in Cumbria in the middle of March.
But it seems that Pero would not settle, and on 8 April he dashed across the field, never to be seen again by his new owner.
He turned up on his previous owners’ doorstep two weeks later.
Shan says it is a total mystery as to how the dog made the 240-mile journey home. He appears to have travelled home unassisted as nobody dropped the dog off.
“It’s a total mystery as to how Pero managed to find his way back to us”, she said. “We know that dogs can find their way home, but 240 miles is a long way to travel.”
The owners now plan to keep Pero, as he seems to have made up his mind about keeping them.
