Missing pooch, Ollie, was found alive at around 12:15pm this afternoon in a dyke between Gainsborough and Heapham.
The one-year-old got out of a smashed car window and ran off after a crash in Gainsborough at the junction of Thorndike Way and Corringham Road at about 5.30pm on Friday, December 20.
His disappearance sparked a huge search effort, with two teams of up to 30 people each setting off into woodland from the Lincolnshire Otter pub in the town this morning.
Belinda Darley, who led the search operation, said: "Half of Gainsborough had been out all morning looking for him.
"We were all exhausted and just about to stop for a cup of tea, and there he was.
"He was absolutely fine, wagging his tail like he has just been out for a walk.
"We have been absolutely gobsmacked by all the support and I would like to thank everybody who came out and helped.”
Ollie is currently at the vets undergoing a precautionary check-up.
