Madison the dog survived the fires in the town of Paradise, which was almost completely razed Andrea Gaylord was reunited with her dog, when she was able to return to the property last week

Madison was there waiting when Andrea Gaylord was allowed back to check on her burned property in Paradise last week.

Ms Gaylord fled when the November 8 Camp Fire broke out and decimated the town of 27,000.

An animal rescuer who responded to Ms Gaylord's request to check on Madison first spotted the male Anatolian shepherd mix several days later.

Shayla Sullivan said the outdoor guard dog was apprehensive and kept his distance.

Ms Sullivan left food and water for him regularly until Ms Gaylord got back last week.

She also helped locate Madison's brother Miguel, another Anatolian shepherd mix that was taken to a shelter 135 kilometres away in the confusing aftermath of the wildfire.

"If [the evacuees] can't be there I'm going to be and I'm not going to give up on their animal until they can get back in," Ms Sullivan said.

The dogs reunited on Friday (local time) when Ms Gaylord came back to the property with Miguel and brought Madison his favourite treat: a box of Wheat Thin crackers.

Ms Gaylord told American news station ABC10 she could not ask for a better animal.

"Imagine the loyalty of hanging in in the worst of circumstances and being here waiting," she said.

"Their instinctual job is to watch the flocks and we're part of them.

"It's a comforting feeling."
