Bernadette Peters devotes herself these days to her pets, Kramer and Stella, and all the abandoned animals of New York.

“What I wanted to do was help shelter animals, to figure out how to solve this problem,” she said.

A decade ago she and pal Mary Tyler Moore began an annual event called Broadway Barks, which raises money for New York-area shelters. Broadway Barks 10 will be performed July 12 in the theater district’s Shubert Alley.

Recently, Peters was approached about writing a children’s book, her first. She agreed. Then her editor said the book needed a song.

“I never wrote a song in my life,” Peters said. “I was in an airplane and I needed a lullaby. Suddenly, the music and lyrics came to me.”

Peters’ book, “Broadway Barks”, is about a homeless pooch named Douglas, will be published next month and is dedicated to investment adviser Michael Wittenberg, Peters’ husband, who died at 43 in a 2005 helicopter crash.

Inside the “Broadway Barks” jacket will be a CD of Peters reading the book and singing her lullaby, “Kramer’s Song.”

“Kramer’s Song” is named for Peters’ older pet, an 11-year-old “shaggy dog, Heinz 57 variety,” she said.

Peters’ other pooch, Stella, is a 10-year-old pit bull.

Several years ago, Peters had a home in northern Miami Beach. Then she discovered a big problem: Pit bulls are illegal in Miami-Dade County which infuriates her.

That’s why we moved to Vero Beach,” Peters said. “We were worried about Stella. … We were afraid they’d take her. You can take any breed and wreck it if you say ‘Fight, fight, fight.’ They’re lap dogs. They’re very loving.”
