In the case of Open Shows, you need to read the schedule carefully. Sometimes the classes are members stakes, and sometimes they are simply stakes classes. At Champ shows, again you'd need to check the elligibility, most are open to all within the class restrictions, and others require membership of some other organisation. The only one I can think of is the Pro Dogs Stakes. Then again, Pedigree asks that you are not in an exclusive advertising contract with any other food manufacturer. So the short answer is read the schedule and definition of classes, as they can vary.
YKC classes require you to be a member, as do JHA, but thats for champ shows. Junior handling at open shows only require you to be a child within the age ranges.
