It is estimated that there are at least 90 million dog owners in the United States. In this new CBS series, owners and their pets - from professionally trained dogs to those dogs simply trained at home - will live together and battle it out in a competition that puts the dog's relationship with the person who has raised and trained it to the test. In the end, only one team of loving owner and faithful dog will emerge victorious in the ultimate search for "Greatest American Dog". The show premieres Thursday, July 10th at 8PM on CBS.
