A dog that refused to stop barking when a fire broke out helped save a mother and her two children from the blaze in the bedroom of a Wanganui house.
The dog's incessant barking drew the children's mother outside to where she saw flames coming from a bedroom window on Monday.
Wanganui Fire Service principal officer Bernie Rush said the family was very lucky and the mother who rescued her children, aged 2 and 4, was a "very brave lady".
Mr Rush said the woman was still distraught at how close they were to a tragedy.
The 8.30pm fire in the house started in a bedroom where it is suspected the children lit the fire with matches.
