Council officers have seized a dog they believe attacked a 95-year-old man in Kaikohe this week.
Jim Morgan was bitten on the hip by one of two dogs that rushed him as he walked past a house in Harold Street on Monday.
The Far North Council impounded two unregistered dogs from the Harold Street house early this morning.
It's not the first time Mr Morgan's been the victim of local dogs.
In December he was forced to have his small terrier put down after it was mauled while the pair were out walking.
He and his dog were also attacked in April 2016.
Far North Council Environmental Services manager Darren Edwards said since Mr Morgan's pet was attacked the council had impounded more than 20 stray dogs in Kaikohe.
But it had not been able to prosecute because of the high level of proof needed.
Mr Edwards said many dog-owners hide their animals after an attack and witnesses are often too frightened of their neighbours to come forward.
