A dog with a heartbreaking back-story is helping to save koala bears in fire-stricken Australia. The pooch, called Bear, has been walking through the country's charred forests in search of the helpless herbivores.

The dog wears special socks to protect him from the burnt ground and has been specially trained to sniff out koala poo and fur.

Bear has bounced back from a tough start in life, after being abandoned by his owners because his obsessive compulsive disorder meant he did not like to play.

However, Sunshine Coast University gave the Border Collie-Koolie cross a fresh start by taking him out of the rescue home and teaching him to scout for koala bears.

The dog and his handler have visited forests in New South Wales, Queensland and Cooroibah in recent weeks.

Animal charity IFAW campaigner Josey Sharrad told the Brisbane Times : "Now, more than ever, saving individual koalas is critical.

"All the while, wildlife will continue to need to be rescued and treated, and might remain in care for some time. The road to recovery will be long."

Firefighters have been filmed saving koala bears from the bushfires in recent days.
