The owner of Odin and Thor, two Northern Inuit dogs who played direwolves in the hit HBO fantasy drama, is facing a growing number of enquiries about pups and has even turned down offers from celebrities wanting to buy the family pets.
William Mulhall, from Co Down, said his dogs, who have their own Facebook, Twitter and Instagram accounts and are insured for £1 million each, have met about 400,000 people in the last four years on the back of their roles as direwolf pups Summer and Grey Wind in season one of Game Of Thrones.
Much of the worldwide hit show is filmed on location at various sites around Northern Ireland.
“Odin and Thor are Northern Inuits, which is a wolf lookalike breed, the closest thing to wolf we can get without a licence,” said Mr Mulhall.

“Their parents were brought in from England, making these the first to be born in Ireland ever - that’s how rare they are.
“Usually when you see a wolf on TV or in a film it will be this breed of dog because they are so wolf-like in their appearance and so highly intelligent.
“And that’s why we got them - we just wanted cool dogs.”
Three weeks after buying the pups seven years ago, Mr Mulhall got a call from the breeder saying a TV show was interested in using them.
“I was like, ‘cool, what’s the show about?’, and the breeder said, ‘I don’t know - swords and shields and stuff’.
“So I brought the dogs up to the breeder’s house and the trainers from Game Of Thrones were there and they picked these two to be in the show as direwolf pups.”
Odin and Thor are not the only members of the family to end up as part of the Game Of Thrones story.
Mr Mulhall has appeared as an extra in the series, while his father played a Dothraki slave master. His two brothers have also been involved, as has one of their boats.
The dogs are now a regular attraction on the burgeoning Game Of Thrones tourism circuit in Northern Ireland, where fans from all over the world visit the locations used in the series.
“A lot of people come here now just because of Game Of Thrones,” said Mr Mulhall.
“We have pretty much met people from all over the place - the Middle East, the Far East, all of the Americas - south and north, all of Europe.
“And all ages as well - from 18 right up to their later years. Because Game Of Thrones really is for everybody - it’s a great show, it’s quite intellectual as well so I think it gets quite a unique audience.”
Mr Mulhall is investigating the possibility of using Odin to father a litter.
“We are looking to keep the blood line going and have a few sons out of Odin,” he said.
“He’s had quite a lot of popular demand asking for pups, so we’ll see what happens in the future.
“We’re just happy to have healthy, happy dogs. They love people, they love being around people.
“They live in the house with us, they have their own sofa. We take them for walks, minimum three miles a day, and they are really quite friendly and affectionate dogs.”
