Three contractors have told how they raced to the aid of a 3-year-old critically injured by a dog that had latched onto his throat.
Paul Tuki, Rob Batt and Louie Wehipeihana were part of a crew replacing water mains in Ashburton when the boy was bitten in the lounge of a relative's home on Wednesday.
It is understood the Doberman-Staffordshire bull terrier cross lunged at the boy's throat as he was eating a chocolate.
The first they knew was when the boy's distressed aunt came running down the side of the house saying a child had been bitten.
Mr Wehipeihana said they expected to see a minor bite, but when the boy's older brother ran out with the victim in his arms and they noticed the blood, they knew it was bad.
