Is your dog super? Do you drink too many Pepsi products for your own good? If the answer is 'Yes' to either of these questions, we've got some upcoming contests to tell you about (and if you win, tell them Firefox sent you).

UNDERDOG Super Pet Contest:
Is your dog super smart?  Super strong?  Then go to the official website and submit a video or photo showing your dog attempting a superfeat, and your pet could appear in "Underdog," coming to theatres on August 9.  Plus, you and Fido get an all-expenses paid trip to the world premiere.  Users vote on the best videos, so get out the vote and campaign for your pooch. 

Transform Your Summer Contest:
Start looking for numbers; codes will be under the caps of specially-marked bottles of 20 oz. and 1 L. bottles of Mountain Dew, Pepsi, and Sierra Mist.  Go to the official website and register your codes for thousands of daily prizes as well as special drawings.  Prizes include the Ultimate Gaming Package (Xbox 360, Panasonic 42" Plasma HDTV, games and accessories), trips to major sporting events, vacation packages and a limited-edition Pepsi(TM) Optimus Prime(R) collectible truck figure.
