A woman savagely mauled by her dog was saved by quick-thinking neighbours who fought off the animal with a rubbish bin.
The 57-year-old was attacked by the male pit bull cross in her home at Portland in Victoria's far southwest about 11am (AEDT) this morning.
She suffered a partially severed right arm, an injured left arm as well as bites to her face.
Police believe a family member alerted neighbours to the dog attack.
They broke a glass panel on the front door to gain access to the scene before reportedly throwing a rubbish bin at the animal.
The dog was then chased into a back room where it was contained before being destroyed by police officers after advice from the city's council.
The victim was flown 400km to The Alfred Hospital in Melbourne to undergo emergency surgery.
She is listed as being in a serious condition and received pain treatment while in the air but was not sedated.
