This first responder is furrier than most.

When one pooch began to drift from shore on a river in Qingyuan, China, Tuesday, an extremely good boy brought it back.

A short video captures the moment a cute black-and-white pup begins yelping as it floats away in a small, blue boat — but that’s when his four-legged friend jumped into action.

A Rottweiler on nearby rocks immediately dove into the water from his dry perch. Adding new meaning to the term “rescue dog,” the large, black Rott chomped on to a rope tied to the vessel — and doggie-paddled his anxious canine cargo back to shore.

Once within a few feet of land, the pup tumbles from the bow into the water — but quickly splashes its way onto land.

A male voice can be heard talking calmly in the background of the video — begging the question, “Why didn’t he lend these two a human hand?”

Perhaps because that would’ve squandered his doggone viral-video opportunity.

This isn’t the first instance of dog heroism — this one just has a happier ending. In March, Rikku — a Siberian husky — died in the act of saving his owners from a two-alarm fire on the Upper West Side.
