Ashlee Simpson, Pete Wentz get help from 'Dog Whisperer' to save baby!

In an episode shot when she was seven months pregnant, Ashlee Simpson-Wentz and "Fall Out Boy" bassist/lyricist Pete Wentz got help from Cesar the Dog Whisperer to ease the aggressive nature of their English bulldog, Hemingway.

Simpson noted: "We're about to have a baby, so it's a big concern."

Fears of how the dog would react around their new baby prompted the intervention. 

"I find myself avoiding other dogs. I avoid going to dog parks with them," admitted Wentz. What, not because of the paparazzi?

Simpson added, "The first time I noticed Hemingway had some issues, whenever I would see him around other dogs, he would [be] aggressive."

Yikes. Look out, Bronx Mowgli. Don't get too close to the nice doggy!
