I'm super psyched for the Greatest American Dog for several reasons – there's quite the cast of characters to watch! Bringing 12 teams of pooches and owners, I can't wait to see how the pageant dogs measure up against the home-trained pups, the purebreds to the mixed, and what goes down when all 24 move in together! Each week a pair will be eliminated 'til one wins the crown . . . and a $250,000 prize! Check out the contestants here and tune in Thurs., July 10 at 8 p.m. for the fur-flyin' premiere!
