An elderly Korean War veteran became a hero on the home front this week — when he used a Christmas decoration to fend off a pit bull attacking a 10-year-old girl, according to a new report.

Leonard Miller, 88, was in the kitchen of his home in Perry Township, Ohio, Sunday afternoon when a 13-year-old neighbor banged on his door, pleading for help.

“She says, ‘The dog has got ahold of my sister and won’t let go, my little sister,'” Miller told local station ABC 5.

Miller ran after the teen to her home, but before going inside, the octogenarian selected a weapon from the neighbors’ yard — a red and white plastic nutcracker decoration

“That’s the only thing I could think of to grab when I went in,” he said.

Inside, he found the family’s white pit bull latched onto the preteen, refusing to release its grip from one of her arms.

“It just had the little girl on the floor and just growling and just shaking her,” Miller told the station. “It was just shaking her, just like a dog would grab a wild animal.”

Miller, who served as an Army combat medic during the Korean War, immediately jumped into action, swiftly putting the nutcracker decoration to use.

“I just kept whacking it on the back of the head and it wouldn’t let loose,” he recalled.

Finally the beast let up — and the girls raced out of the home. Miller yelled at the dog, afraid he’d become its next target.

“I said, ‘No!’ It was real loud, about three or four times,” he told the outlet.

Then the neighborhood hero returned home, called 911 and tended to the injured girl, wrapping a wet rag around her arm, according to the report.

“The paramedics and everyone that was there, they said, ‘You saved that little girl’s life,'” Miller told the outlet.

The family thanked their neighbor and told him the girl underwent surgery for severe arm injuries on Monday.

Miller told the station he didn’t want to be called a hero — he simply did what he could to save his young neighbor.

“I couldn’t sleep last night,” he told the station. “I’m just glad I was there to help her.”

The pit bull was deemed a “vicious animal” by the Stark County dog warden, who gave the family 10 days to appeal, according to the report.

But the family gave up their pet voluntarily and it was euthanized on Monday.
