Robert Pattinson's first dog with Kristen Stewart was supposed to be a "big man's dog."

The Twilight Saga: Breaking Dawn Part 2 star - who recently reunited and moved back in with his 22-year-old girlfriend following her "momentary indiscretion" with director Rupert Sanders in August - has opened up about their first rescue puppy Bear and his pampered lifestyle.

"He was supposed to be a big man's dog. But he just kind of got stunted," he said on The Ellen DeGeneres Show.

The couple of four years adopted the dog from a Louisiana shelter and the 26-year-old revealed that he instantly became a pampered pouch: "We were staying at the Four Seasons afterward. He didn't have any dog food so I got him a little plate of prosciutto."

Robert's comments come just days after Kristen - who refers to Bear as her child - gushed about the couple's new dog Bernie and what it was like introducing him to Bear. "He's my child, I love him. I raised Bear, we got her when she was like... She (Bernie) was emotionally manipulative and really milked it, and I got her home and she was like 'I am fine.' She was taking Bear's stuff, I was like 'you need to slow your roll,'" she said.
