While some Western NSW councils euthanise with a single gunshot, most regional and metropolitan councils use lethal injection.

Dubbo City Council's manager of environmental control Debbie Archer said the council's preferred option was euthanasia by lethal injection.

The operation of Dubbo City Council's Animal Shelter is contracted to the RSPCA," she said.

"All animals euthanised at the Dubbo Animal Shelter are done so in accordance with RSPCA policies and by RSPCA trained staff.

"Injured animals may also be euthanised by a vet following veterinary assessment and advice."

The RSPCA utilise the services of a contractor to collect the animals after being euthanized and they are transported and cremated at an approved facility, Ms Archer said.

Where Council has enforced that an animal is to be euthanised, like a dangerous dog, the owner is given an option to claim the body for their own burial."

Walgett Shire Council director of planning and regulatory services Matthew Goodwin said, while council still administered a gun shot to euthanise animals, all of its procedures were now under review.

"Some people support our current practices and others are wanting change," he said.

"We will consider the range of community views before making any decision."
