She managed to lift her brother over a fence before jumping the fence herself to escape further attack.
The woman was off work for two days.
Her brother was left with deep scratches and bruising.
Brent Lincoln, team leader of animal services at Tauranga City Council, said the dog was destroyed on Friday after its owner surrendered it.
Crawley pleaded guilty in Tauranga District Court last month to a charge of being the owner of a dog which attacked a person.
She was fined $250 plus $132.89 court costs and ordered to pay $300 towards the victims' medical expenses, which she had already offered to do.
Crawley pleaded with Judge Robert Wolff to not sign the destruction order as it was a guard dog and a beloved pet.
But Judge Wolff told Crawley that "his hands were tied".
This case followed that of a 13-year-old Te Puke girl whose arm was bitten when she was attacked by a neighbour's pitbull in Maketu last month.
