“Gunyah” property owner Peter Holley said he had seen the dog over the years, but had not managed to get close to the animal until last week.

He shot the dog before handing it over to the New England Livestock Health and Pest Authority (LHPA).

Mr Holley said the dog was the biggest wild dog he had seen.

LHPA senior ranger Mark Tarrant said wild dogs remained a significant problem in the area.

Mr Tarrant urged landholders to contact the LHPA if they had wild dogs on their property.

He said the LHPA could assist with aerial and ground baiting programs.

The LHPA started its annual, large scale wild dog baiting program targeting wild dogs from Nowendoc along the Great Dividing Range to the Queensland border in April.

The annual wild dog baiting program brings together 20 wild dog associations, National Parks and Wildlife Service (NPWS), and Forests NSW, and includes extensive aerial and ground baiting over private and public land.

"Aerial baiting is a key activity prioritised by public and private land managers as part of the region wide wild dog management plan,” Mr Tarrant said.

Mr Tarrant encouraged landholders to undertake ground baiting in non-aerial baited areas.
