Several impounded dogs due to be rescued by a shelter have instead been shot dead by a rural council in NSW under its interpretation of COVID-19 restrictions, alarming animal activists and prompting a government probe.

Bourke Shire Council, in the state’s north-west, killed the dogs to prevent volunteers at a Cobar-based animal shelter from travelling to pick up the animals last week, according to council’s watchdog, the Office of Local Government.

“OLG has been informed that the council decided to take this course of action to protect its employees and community, including vulnerable Aboriginal populations, from the risk of COVID-19 transmission,” a spokesman from the government agency said.

The spokesman said the agency was examining the circumstances of the incident to find out whether companion animal and cruelty prevention laws had been broken.
