Lucky dog.

Dramatic first-person footage shows the moment a firefighter broke down a window to save an adorable pooch from a burning barn in Pennsylvania.

In the daring rescue Saturday, firefighter Ryan Balmer’s helmet camera captures the dog — which appears to be a black lab — frantically barking and trapped in the flame-engulfed building in Warwick Township, according to KCTV5.

“Come on, buddy!,” Balmer shouts, trying to encourage the pup to jump out the first-floor window.

But when the frightened dog wouldn’t jump, Balmer busts through the window himself, climbs inside and lifts the pet to safety.

“I was hoping [the dog] was going to jump out the window,” Balmer, of the Lititz Fire Company, told the local station. 

“It didn’t want to. It kinda got scared and ran back in. So at that point then I made the decision to bust the window out, climb in, and help the dog out.”

Once free, the pooch promptly scampers over to his owner, who is waiting near the barn, the footage shows.

“If that [was] my dog in there I would want someone to go in and try to get it out,” Balmer told the station.

“We have a saying in the fire service, ‘risk a lot to save a lot.’ For that family I’m sure that dog means a lot.”

Nobody was injured in the fire. It wasn’t immediately clear what sparked the blaze.

In 2018, footage of a firefighter rescuing a dog in northern California was also captured by a helmet camera.
