Breeder: pet or show

I am currently talking to a breeder of a rare breed about potentially bringing home a puppy from her in 2027. I already have a one year old pup of a different breed and when I brought him home, I wasn’t fully aware of everything that goes into ethical breeding. Since then, I’ve done a lot of research and have learned so much more about the sport and show world and I’ve realized I may be interested in bringing home a dog with potential for sport or conformation. The breeder has said she’d be willing to teach me about showing, which I really appreciate. I have also looked into trainers for the sports I’d be interested in and currently have my pup trying some out. I just worry about committing to a sport/show prospect and then not titling the dog to the level that might be expected. She is aware of the experience I don’t have. Could I ask for a pet-quality dog that still has the potential to participate in sport or possibly show? I just want to make sure I’m being realistic about my goals and experience. I also don’t want to get a dog that thrives for sports and I don’t live up to that for them.
