A charity that took in a dog found on England's highest peak say the case highlights the need for microchipping.
The Scottish SPCA had to appeal for the dog's owner to come forward after he was discovered on Scafell Pike, because he was not microchipped.
A week later and the dog has now returned home, after spending time at an animal welfare and rehoming centre in Glasgow.
Centre assistant manager Katrina Cavanagh said:
A major search operation is underway in the Lake District, by a couple who are looking for their lost pet.
They've spent hundrends of pounds and travelled thousands of miles in the search for their Jack Russell.
Paul and Wendy Meadows, who live in Southport, have travelled to Patterdale near Ullswater almost every day.
