Greatest American Dog premiered on CBS on July 10, 2008. Twelve extraordinary teams of dogs and owners from across the nation will compete for the title of Greatest American Dog. Owners and their pets - from pageant dogs to those simply trained at home - will live together and compete against each other in challenges that put the owners' ability to train their dogs to the test. Each week, the judge will eliminate one dog and their owner. The last remaining team will walk away with a $250,000 cash prize and the title of Greatest American Dog.
