‘Peter’ pooch: from death-row stray to off-B’way

Her Playbill bio is longer than that of some of her co-stars. Then again, she’s had a helluva life, having narrowly escaped death row. Now, after three years on the road with “Annie,” Macy (left), a 9year-old mixed terrier, is making her off-Broadway debut. In “For Peter Pan on Her 70th Birthday,” which opens Wednesday at Mainstage Theater, she’s billed simply as “a dog.” (Talk about typecasting.) One of her more significant bits of stage business involves gob-ling up some dropped cereal. All told, iit’s a long way from Oklahoma, where animal trainer Bill Ber- loni found Macy in December 2009.

“It’s a harrowing story,” Berloni told The Post.

He said the wheat-colored stray somehow landed in a Oklahoma City pound where dogs that go unadopted after 10 days are put down.

No one, it seemed, wanted to adopt a scruffy 2-year-old terrier, but staffers didn’t have the heart to euthanize her. And so they kept switching her cage cards, Berloni said, fudging her admission date to give her more time.

The staff ’s next move was enrolling Macy in an Oklahoma corrections program in which inmates teach dogs obedience skills. Three months later, she graduated at the top of her class, Berloni said. But on the prison’s adoption day, no one claimed her.

And so Macy ended up back at the shelter. Desperate, the staff reached out to a woman who rescued Dalmations. She agreed to board Macy and listed her profile on Petfinder. That’s where Berloni, who works in New York and was searching for a Sandy for the “Annie” road tour, spotted her.

He flew to Oklahoma and “adopted her on the spot,” Berloni said.

In between “Annie” gigs, she made a few Purina spots.

“Peter” ends its run Oct. 1, but Macy has already lined up her next show: another “Annie,” at New Jersey’s Paper Mill Playhouse. “I think her biggest talent is her ability to adapt and survive,” Berloni said. “No matter what we throw at her, she seems to figure it out. She’s a pro.”
