Who makes the rules, and how to contact themThere are 5 major agility organizations in the United States. Each one has slightly different rules and requirements of Dog/handler. Titles/levels from the various organizations cannot be mixed and matched. For example, Even if you earn an advanced title in AKC, you must still start in the first level of USDAA. Although each of the organizations uses most of the same obstacles, there are a few that are unique to one or the other, and there might be some slight differences in the obstacle specifications for the different organizations.
