There is a registry called IABCA (I think that stands for International All Breeds Club of America) which awards an International Champion title. The dog's are judged against a standard, not in a class with other dogs, and receive a hand-written judge's assessment with a score. Three scores which meet the standard will give the dog the title, which can be earned in one weekend.
I've heard some folks recommend the shows as a more relaxed way to get into dog showing, but also that the title is not considered to be worth much of anything by serious showing people. There can be several dogs who earn top dog honors in the same class, so long as they earn the same score, and it appears to be an easy way to get letters in front of the name of dogs which would be considered substandard in the AKC show ring.
What I just typed is old information and I couldn't find much that was newer, so it may be out-dated and inaccurate.
