A passer-by is being hailed a hero after he jumped over a fence and repeatedly whacked a dog with a broom stick to stop it from attacking its owner.
A woman is in Waikato Hospital with "significant" injuries to her face and neck after she was attacked by the dog that she had raised since it was a pup.
A Hamilton man, described as being in his late 20s, was walking past the Avalon Dr property in Hamilton at about 3pm today on his way back from the doctors when he saw the woman in her 30s pinned to the ground on her front yard.
He jumped over the side fence and started hitting the five-and-half-year-old mastiff cross with a broom that had been lying on the lawn.
Neighbour Sheryl Featonby said she opened the front door and initially thought the man was attacking the woman before realising he was trying to stop the dog who was tearing huge hunks of skin off the woman's stomach, face and neck.
