Hi Claire, if your puppy won say, best puppy in breed, he would be eligible for the puppy group. Mostly, the AV classes are judged after the groups in any case. If you won puppy group 1, it would be a good idea to to withdraw from subsequent variety competition, to remain eligible for best puppy in show. :)
There are sometimes stakes at Open shows as well as Champ shows.
