Bobby was extremely ill when he arrived at the surgery, having suffered the toxic effects of smoke inhalation, Mr Kelly said.
"He went into intensive care. We were unsure if he would make it in those early stages. He couldn't breath properly. He had damage to his upper airways and lungs. His mouth was burnt with ulcers and the cornea off his eyes had ulcers. He was in shock and couldn't eat."
A feeding tube was inserted through the dog's neck.
"He couldn't swallow and it was painful for him to breathe ... it can be a very serious condition."
The dog's health would be compromised for some time yet while his lungs fully recovered, he added.
' The family already had enough to cope with, without having to deal with a bill they couldn't afford, Mr Kelly said.
"It just makes sense," he said.
"They can't afford the bill and they have enough to worry about. It's one way to support the community. It's an early Christmas present for them." Meanwhile, the family have "invaded" Mrs Waiapu's brother's home until they find a new one and they are overwhelmed by the support from the community.
They had been inundated with donations of clothes, whiteware and furniture, Mrs Waiapu said.
"It's been incredible. We've had so much support from our neighbour school, Sunset Primary, the community and kura where I work. It warms your heart to know everyone cares so much. We'd just like our own place."
