"She was very emotionally manipulative. She really milked it," the Twilight starlet told Kelly Ripa on Wednesday's episode of Live! With Kelly and Michael. "Then I got her home, and she was like, 'I have arrived.'"
But while Bernie wasted no time making herself at home with an A-list star, with Stewart again comparing the pet to a "roommate," her other rescue dog, Bear, didn't fare as well with the adjustment.
"She was very comfortable instantly," Stewart says of Bernie, "taking Bear's stuff. I was like, 'You need to slow your roll, girl. You need to watch it!'"
Asked by Ripa if she wanted to provide a playmate for Bear, the 22-year-old says it was a simpler motivation that led her to adopt again.
"I'm just sort of obsessed with rescuing the pooches," Stewart said.
