The SPCA is reviewing its procedures around dogs after a volunteer was mauled by a "family" dog that had shown no hint of aggression until it attacked.
The experienced volunteer, known as Paula, was with the dog, a 5-year-old Border collie, and two smaller dogs in a pen last Friday when something caused the dog to attack.
"There were absolutely no indications of aggression or risk with this dog. We've reviewed all the history - from the moment it was dropped off and its journey in the SPCA - and, in fact, this dog showed no issues whatsoever," Auckland SPCA chief executive Christine Kalin said.
But then last week it attacked Paula, aged in her 40s, leaving her with several wounds on her legs and an arm.
Paula screamed and tried to push the dog off her but it kept biting her legs and her arm. After several bites the dog stopped and she was able to leave the pen, but "unfortunately the dog followed".
