9. Dolce in 'Young Adult'

Hummer, the Pomeranian who plays Charlize Theron’s neglected pet, was "discovered" by director Jason Reitman on the streets of New York City, according to the New York Times. "You know why I chose the dog?” Reitman explained: “Because a Pomeranian is the only dog that has to smile, genetically. Imagine, this woman chose a dog that no matter what she did to it ...  all the dog ever did was smile back to her." Awww!
