Brad Pitt’s Bulldog Is One Pushy Pooch

Brad Pitt may be the star -- but tell that to his bulldog. When the actor recently brought his pooch along to keep him company at a Parade magazine photo shoot, the dog (whose name we don't know) ended up running the show. He even managed to get front and center in some of the pictures! "He organically popped up in the shots after the shoot began," photographer Michael Muller tells PEOPLE Pets.

So, how did the pup's close-up come about? "Brad's bulldog was challenging us all by not turning around," explains Mueller. "So his backside was facing the camera! That's why Brad was smiling – we all got a laugh about it."

The actor, 45, talks to the magazine about fatherhood has shifted his perspective. "Children are a dominant value in my life now, and they weren't before," he says. "They were always something I thought I'd get around to having when the time was right."

Now dad to six children with partner Angelina Jolie, Pitt has surrendered to the chaos of their busy existence. "This family is full of life! There are laughs, aggravations, irritations, but at the end of the day, it's fun," he says. "When life is really good, it's messy." And we bet that rascally bulldog has something to do with the mess!
