MOST AKC dog shows have conformation and junior showmanship along with obedience and rally. Occasionally agility might also be included, but not often, as it takes a lot more space. In recent years, AKC has experienced a steady decline in registration and dog show attendance. This has resulted in more and larger 'circuits' to help defray the cost of locations. The reduced numbers of exhibitors means stronger competition. Owner handlers have a harder time attending 3-5 day 'weekends,', but handlers make their living this way, so the more shows in one location the better and they become a major contributor to the entries. (Each day is a complete show and you can pick and choose the day(s) you wish to attend.) Many of the judges are also there for the whole weekend, being juggled around to judge different breeds/groups/BIS on different days. It is sometimes difficult to 'pop in' for one day of a circuit and do well.
In the past several years, AKC has added incentives to attract more exhibitors with BEST PUPPY IN SHOW, BEST BRED BY EXHIBITOR IN SHOW, GRAND CHAMPIONSHIP TITLE, and, most recently, mixed-breeds welcome in obedience, rally, and agility. (These are 'options' each club can partake of, to help enhance their show, it is not required.) Personally, I haven't seen them make much difference.
In addition, entry fees have escalated. When I started to show in 1968, a single entry was $7.00 with free JrShow and reduced fees for Puppy & BredBy. Now it's $25.00 to $30.00 a dog with no freebees or reduced rates. Of course, everything else has increased, so why not that? But, along with traveling expenses, motels, and meals (not to mention the products & do-dads you may purchase), it can become a pricey weekend. If you go home with nothing (no points), it can be depressing. There are RARELY any trophies (except for groups & BIS) and there is NO MONEY to be won.
It takes 15 points to complete a championship title with two major wins (which are 3,4,5 pts) under two different judges. The points are calculated by the number of entries in your breed. There are no points if you end up being the only dog of that breed (unless you get a Group ONE).
