A dog missing for three days underground on the New South Wales South Coast has been pulled out alive.

Late on Friday night, the Shoalhaven community kept digging for the American Bulldog after emergency services had given up.

Just after 10:30pm Brooklyn was reunited with his owner, Charlie Griffith, before being taken to a veterinarian for treatment.

Brooklyn chased a wombat down a burrow along the Bens Walk bush track at Nowra on Wednesday, and could be heard barking and whimpering around seven metres underground.

Crews from Wildlife Rescue South Coast, New South Wales Fire and Rescue and NSW Ambulance Rescue used shovels, crowbars and a jackhammer to try and free the dog in the days earlier.

A $30,000 optic fibre camera and sensitive sound equipment was also unsuccessfully used to try and locate the dog in the network of wombat tunnels.

On Friday afternoon, Shoalhaven Fire Station officer, Ian Walters said the operation had to be called off as there was no longer signs the dog was alive.

"We haven't heard any noise from the dog or the wombat this morning," Mr Walters said.

He said the rescue effort had been challenging, particularly due to the size of the wombat hole.

"A wombat hole is not just a straight tunnel, they can go quite deep," Mr Walters said.

"This cave or the tunnel that the wombat lives in is probably 10 to 15 metres long and some parts of it go down four metres, maybe a little bit more."

But the Nowra community wasn't convinced, and started their own effort to find Brooklyn.

It's reported more than one hundred residents donned head torches, brought shovels and used old fashioned elbow grease to dig the three-year-old dog to freedom.

It's unclear how much the search and rescue effort has cost but Mr Griffith said he's grateful for the support he's received.

Brooklyn is believed to be in good health.
