A DOG alerted its owners to a fire at their home in Portishead in the early hours of the morning.

A fire broke out at a cottage in Pinecroft, with two fire engines from Portishead station and one from Avonmouth called at about 1.17am.

Six firefighters wearing breathing apparatus tackled the blaze, which had taken hold of the roof of the cottage, using two high pressure hose reels and a 45mm jet.

They also stripped away several roof tiles to access the fire and make sure it was put out.

A spokesman for Avon Fire and Rescue said it is thought the fire started accidentally in one of the cottage’s bedrooms where there was a wood burning stove.

The couple who lived in the house, which was badly damaged in the blaze, were alerted to the fire by their dog. They were then able to leave the cottage and dial 999.

The Red Cross Fire and Emergency Support Service were also on hand after the fire to offer advice and support to the residents.
