The Big Miracle star and fiancé Will Kopelman took another big step together on Sunday, adopting an 8-week-old rescue puppy from Bark n' Bitches, a humane pet shop in Hollywood, Calif.
For Barrymore, a longtime animal rescue advocate and fan of dogs, the step was a natural one, but for Kopelman, it was a first. The New York City native has never had a dog before, and after finding the puppy on Petfinder, stopped by the shop with Barrymore to get to know the dog.
"They really were very thoughtful and not impulsive about making the decision," Bark n' Bitches owner Shannon von Roemer tells PEOPLE. "Drew, being such a huge dog fanatic, was great to Will. She really wanted him to feel it out and make the decision."
The shepherd mix puppy, whose new name is Oliver, was part of a litter left in a box outside the door of a Los Angeles-area shelter. Half the litter was rescued by von Roemer. And in an only-in-Hollywood twist, the pups were then fostered by Twilight actress Nikki Reed and husband Paul McDonald.
Reed, who Tweeted frequently about her exploits with the dogs, had a sad goodbye when they left. "My heart hurts," she wrote last week.
She'll be happy to know that at least one of the puppies has already found a great new home. In an interview on The Ellen Degeneres Show airing Wednesday, Barrymore said, "I think Ollie hopefully has hit the jackpot."
Barrymore said that she, too, feels like she got lucky – in love. "He's a good man," she said of her fiancé. "He's a good person and I just feel really lucky and really happy and really calm. Which is a really wonderful feeling."
