Julia Roberts, Biscuit and Butterscotch have all been adopted.
People looking to adopt from the Sato Project go through a rigorous application process that includes a five-page application, personal and professional references and a home check.
"These dogs have been through so much already. I'm not putting them in anything less than a perfect home," Beckles said.
The project spends an average of $600-$800 in veterinary services for each dog before putting it on a plane. Some have had health costs up to $10,000.
"I will never make a decision about a dog's health based on money," Beckles said. "I figure, that's what American Express is for."
The British-born Beckles has two of her own dogs, including a Puerto Rican rescue named Boom Boom, which is also her nickname in her second career as a competitive boxer. The Sato Project's office is in the famed boxing gym Gleason's in Brooklyn, N.Y.
Beckles knows she gave up a comfortable New York job for a passion that comes with both triumph and heartbreak, but knows she made the right decision.
"You're only here once, as far as I know, and nothing makes me happier than doing this," she said. "Some of the things I see break me, but I'll always bo back for the next dog and when I see dogs like Butterscotch and Biscuit and I know what their life could have been like or how it is now, it inspires me that every dog should be given that chance."
