Three fire engines from across Lancashire were called to Bretherton on Sunday afternoon after a horse was reported as being stuck in a ditch.
Firefighters from Penwortham, Tarleton, and St Annes, along with a rope rescue unit, attended the scene on Eyes Lane at 2:23pm.
A JCB telehandler was used to release the horse which had become stuck up to its back in mud.
A Penwortham Fire Station spokesman said: "After we arrived on the scene, the horse was out within 45 minutes.
"After an hour or so it was up on its feet."
