A pet dog trapped in a wombat tunnel on the NSW South Coast for three days is recovering in the care of his owner following a successful rescue effort by locals last night.

Three-year-old Brooklyn the bulldog became trapped in a labyrinth of tunnels after chasing a wombat down into the burrows in Nowra on Wednesday.

Video shows the dog's emotional reunion with owner, Charlie Griffith, just after 10.30pm by the Shoalhaven community, who continued to dig for the missing pet after emergency services called off their search.

Mr Griffith, who lives in a tent in a nearby park, has expressed gratitude to all those helped with Brooklyn’s rescue, in what one community member has described as a show of community spirit.

“Thanks heaps! Tremendous effort. Like I can't believe it,” Mr Griffith told 9NEWS.

Brooklyn has since been given the all clear from vets and is believed to be recovering well in the care of his owner.

Previously specialist urban search and rescue firefighters had been looking for the 42kg dog, using special audio and seismic devices in the search.

After three days there were "no longer any signs of life", Fire and Rescue NSW Superintendent David Lewis said, and the search was ended.

However, Mr Griffith and the local community were determined to continue the search.

More than 100 residents used torches and shovels to continue searching the wombat tunnels to help rescue Brooklyn.
