The dog, named Bear, helped save the injured koalas following wildfires which devastated swathes of New South Wales (NSW). Wearing socks to protect his paws, he went into into burnt-out areas to detect the native Australian animals by sniffing out their faeces and fur.
Bear was given up by his former owners as he was not well suited to life as a pet because he was intelligent and highly energetic.
He now works as a koala detection dog for the International Fund for Animal Welfare (IFAW) alongside his handler, Rianna. When the pet-turned-rescue dog smells a koala, he sits very still to alert Rianna that an animal is nearby.
