I would leave all options open. Not all dogs that are shown are used for breeding. If the dog is a good representative of the breed and conforms closely to the standard, certainly, conformation is always an option. Yes, most consider Conformation for breeding stock, but it is also a good way to show what is being produced by a certain dog, pair or kennel.
Another option UKC Licensed Altered Classes (if available in your area). Again, showing what is being produced.
There are always performance events: Obedience, Rally, PP, ScH, Lure Coursing, Tracking, S&R
It's all about finding the event(s) your dog enjoys and excels at. Some enjoy one over many others, yet some enjoy multiple
events.
