A rudimentary understanding of the proper procedures associated with measuring and weighing is necessary as all judges approved for at least one breed are eligible to judge an NOHS group and FSS Open Shows. As all groups contain measurable and/or weighable breeds, and FSS and Miscellaneous breeds may have height/weight disqualifications, all judges are eligible to judge a competition in which dogs may be measured or weighed.Furter, judges may be asked to judge a breed or group as an emergency replacement or invited to judge a sweepstakes or futurity for a measurable breed. It is worth noting the procedural exam for first time judging applicants also contains questions covering these concepts regardless of the breed(s) one is applying for.
