A Great Pyrenees who saved his foster family from a fire on their houseboat has been adopted just 1 day later by a secret admirer.

The fluffy white dog named Moose alerted Sheila Janes and her husband Chris, asleep on their houseboat, that a fire had broken out on another boat moored nearby which quickly spread to their own, ready to consume them all.

More remarkably, Moose was only with the family for 48 hours-he was a foster dog who Sheila and Chris thought would give a weekend of fun for their three kids.

They first came to know Moose when they discovered the Portsmouth Humane Society's ‘Paws Around Portsmouth' weekend foster program.

They were having so much fun doing all kinds of activities, and it was at a farmers market that they met someone who wanted to adopt the pooch.

"The paperwork was to be finalized the next day, so we had one last night with Moose before he went to his new home. We spoiled him that day with an ice cream pup cup, a visit to the park, and a chicken sandwich," said Sheila, adding that they decided to keep him at their houseboat rather than bring him back to the shelter.

That night, their houseboat caught fire, and the impromptu sleepover guest potentially saved all 5 of them. Moose was hailed as a hero and followed through with the paperwork the following day.

However, the new family and home wasn't the right fit for the big athletic dog.

Watching local news coverage and social media updates from afar was Ciara Hill. Proud owner of dogs, cats, chickens, and a tortoise on 5 acres of land, when she heard that Moose's original adoption fell through, her husband gave her the green light for the plus-one.

"We saw that he had been returned, and I was talking to my husband. He was like, 'Well, go get him,'" Hill told WTKR. "My other animals are welcoming him in, and he seems to be pretty comfortable."
