Barron Trump, the youngest of the president-elect’s five children, smiled when he met 9-week-old Goldendoodle Patton.

The pooch may soon find himself living at the most famous address in the world.

Florida philanthropist Lois Pope is trying to get the Trumps to adopt Patton, according to the Washington Post.

She pitched the soon-to-be first family during Thanksgiving at Mar-a-Lago.

President-elect Trump reportedly gave the OK for his son to meet the young canine.

“He said, ‘Go over there and show it to Barron,’” Pope told the Washington Post.“

“He said, ‘He’s going to fall in love with him.’ He said, ‘Barron will want him,’” the philanthropist said.

So she did. And a “big smile came over his face, and it just brought tears to his eyes.”

The Trumps aren’t dog owners. But presidents usually are.

The Obamas have two Portuguese Water Dogs, Sonny and Bo.

But if the president-elect is about to adopt a dog, he isn’t saying.

Asked three weeks ago whether he’d be getting one, spokeswoman Hope Hicks told The Post, “He has not made a decision.”

Hicks reiterated her statement in an email Wednesday, saying her comment still “stands.”
