At Disney.com, consumers can upload photos and videos of their dogs until June 1. Ten videos and 10 images will be chosen as finalists with consumers voting online for the winners in different categories. Each winner will get a trip to the "Underdog" premiere in Los Angeles. The movie goes to theaters Aug. 3.
In addition to a trip to the world premiere, an unlimited number of entries will appear in the film's end credits, allowing selected participants to see their dogs in a movie theater on the big screen.
