An ex-gal pal of Keith Raniere says the Nxivm sex cult leader terrorized her after they ended their abusive decade-long relationship — claiming he hired people to stalk her and possibly kill her dog, according to a new report.

Toni Natalie dated Raniere in the 1990s and early 2000s and maintains she was one of the first women “indoctrinated” into his group — claiming the convicted sex trafficker repeatedly raped her during their relationship, according to a preview of her new memoir obtained by Radar Online.

In her tell-all, “The Program: Inside the Mind of Keith Raniere and the Rise and Fall of Nxivm,” Natalie alleges the abuse didn’t stop when their relationship ended — and that her ex hired people to stalk and harass her.

“Someone would break into my home, mess my bed, open the cabinets in the kitchen, rearrange the artwork on the wall, and make off with some of my clothes,” Natalie wrote, according to Radar Online.

“This happened more than a dozen times and was extremely terrifying. I did not feel safe in my own home. I’d pack up my dogs and go to a hotel.”

After being diagnosed with post-traumatic stress disorder in 2004, Natalie says one one of her beloved dogs, a German Shepherd named Jake, got sick after eating what she thought was a bad batch of dog food.

“I brought him to the vet, hysterical, but there was nothing that could be done,” she wrote.

Years later, another of Raniere’s girlfriends, Kristin Keefe, reportedly hinted to Natalie that a private detective in charge of staking out her house had poisoned the dog.

“Keith Raniere killed my dog,” Natalie wrote according to Radar Online.

In June, Raniere, 56, was found guilty for running the upstate sex cult — where women were branded with his initials and forced to have sex with him — and was convicted on counts including forced labor, racketeering and sex trafficking.

He faces a minimum prison term of 15 years and a possible life sentence.
