Vanessa Lachey has a full house: three kids, husband Nick Lachey and a dog named Wookie, who makes sure his presence is known. In the fifth episode of "My Pet Tale," Lachey explains how Wookie fits into her family.

Vanessa Lachey imitates a famous Star Wars character to call her dog over copied! Wookie, now 11 years old, taught her a great deal about motherhood before she started having kids with husband Nick Lachey.
