The Fashion Star judge and her husband, Joel Madden, brought home an 18-month-old German shepherd last week, but the responsibility is all Daddy's, she tells Ellen DeGeneres on Thursday's Ellen DeGeneres Show.
"I actually told Joel I don't want to pick up after anything ever again," Richie says. "I've got my kids, so I'm going to let you do that. It's his dog, but I like to, you know, snuggle. I like to hug him and kiss him."
The adoption of the adorable black pooch named Ero, the first family pet for the Richie-Maddens, was Madden's idea and garnered the support of the couple's 3-year-old son, Sparrow.
"Joel really wanted the dog. My daughter did not want a dog, and Sparrow was really excited about it," she says.
The "sweet" pup has only been with the family about a week but 4½-year-old Harlow is already warming up. "She doesn't like anything disturbing her space," Richie explains. "She's definitely coming around. She's down."
