The internet’s new top dog is an adorable, subway-riding bear-cloud

He’s a ruff rider.

A Chelsea woman has found a clever loophole to bring her huge — and overwhelmingly adorable — dog Lumi on the New York City subway.

Jackie Hornung, 24, carries the 52-pound, 1 ½-year-old Samoyed in a hiking backpack to comply with the MTA’s rule that “no person may bring any animal on or into any conveyance or facility unless enclosed in a container.”

Most people leave their larger dogs at home and tote only tiny Yorkies or teacup poodles, so the sight of Lumi stuns some straphangers.

“There’s definitely a lot of stares, a lot of laughs and lots of pictures,” Hornung, a medical assistant at Weill Cornell, told The Post.

“People are coming up, saying, ‘Oh my God, he’s so fuzzy. Can I pet him?’”
