Eighteen firefighters from across West Cornwall were called to rescue a dog that had fallen down a mine shaft near Pendeen this week.
The cocker spaniel, called Jervis, had become stuck down the shaft on Monday around 2pm.
Firefighters from St Just and Penzance attended the incident, as did a specialist "line rescue" appliance from Camborne.
Jenna Gendall, from Cornwall Fire and Rescue Service, said: "On their arrival fire crews cleared around the shaft opening.
"Once cleared they lowered a firefighter using the lines and harness and a triple extension ladder.
"The firefighter being lowered monitored the shaft atmosphere using a gas detector.
"The cocker spaniel was found five metres down from the shaft entrance, at the bottom of the dry pit."
Jervis was brought back up to the surface and reunited with his owner, unharmed.
