A lucky family escaped a fire at their Skyline Acres home in Fredericton on Sunday, but the family’s dog didn't make it out alive.

Fire crews responded to a fire at 26 Beaconsfield Drive just before 11:30 a.m.

Neighbours said the family, including three children, had left about 45 minutes before the fire was reported. Heavy smoke was seen coming from the house and half of the basement was engulfed in flames

No one was injured.

Firefighters said there is extensive damage to one side of the basement, a lot of smoke and heat damage and some smoke damage upstairs.

They are not clear yet how bad the damages are or whether the house is salvageable.

The cause of the fire is still under investigation.
