"Hunter was on death's door. The young firefighter ... had him on oxygen and was looking after him."
Brent Lusis, a Navy officer, received burns to his hand and face and faces skin graft operations. The rest of the family were unhurt. Hunter needed a blood transfusion but is recovering at home.
Devonport station manager Greg Booker said the fire service's first priority was saving human lives but they were happy to help pets when they could.
"We all know pets are part of the family."
The fire started about 3am last Sunday. Jordan woke thirsty and noticed a flickering light outside his bedroom window.
"He got up and saw the back deck was on fire, ran in and told us," Dennise said.
