Well, I would just be honest with the breeder that you have never had a show dog and are not sure if it is something you will enjoy or not even if it is just sitting on the sidelines and watching him in the ring with her. That you wouldn't mind giving it a try but that if it isn't working out you want to be able to neuter and just have your companion dog.
I agree with Pat and Lvoss. Just wait and see….. If the puppy that she thinks would best fit your family is show quality at eight weeks, and you are interested in having him shown, or showing him, then by all means go for it.
I wouldn't spend a lot of time worrying about it now, because you just don't know how the litter will turn out. As Pat said, everybody plans that there will be at least one show dog in a litter...and hopes that there may be more. But there are usually more pet puppies in any given litter than show pupies....even if they all are capable of finishing their championship.
And, as Pat said...Limited Registration is for pets that are not intended to be shown and bred...Full registration is for dogs that may be shown and bred from. You can change full to limited, but not limited to full (I think..)
And if you decide to do the show thing, there will probably be a contract that spells out what the breeder expects you to do to have the dog ready for the show ring or testing that will need to be done before breeding...lots of breeders only sell show stock on a co-ownership, particularly to new exhibitors.
Good luck, let us know what you decide
