The search for the pack of six dogs that attacked 95-year-old Jim Morgan's dog Sandy in Kaikohe's Harold Ave on December 16 has so far failed to find the animals or their owner.
There was initial hope that Sandy could be saved by the amputation of his left hind leg, but the dog had to be put down two days later.
Far North District Council environmental services manager Darren Edwards said the animal management team had investigated tips from the public, but neither the dogs, nor their owner — who was apparently riding a blue quad bike and was believed to be local — had been identified.
Staff would continue to canvass residents in the hope that someone could provide the information needed.
