OK heres my input-
As for bitches and unwanted litters, this is why I chose a male - should anything happen, it would fall on the owner of the bitch, not me. (legally you cant prove whos the daddy in dogs as a litter can have multiple fathers)
Secondly, go to the TSC and buy you a 10x10 kennel run, if your parents wont pay for it now, get you a job in April and save your paychecks for the kennel. Until then, that dog is NOT to be allowed out unsupervised for any reason and put her on a 6 ft. leash, no longer so you can ward off the studs on walks.
Lastly, you are young, conformation is a hard show ring to be in, like everyone else said said and reinstated, have her spayed and participate in handling-based shows such as obedience, agility or even AKC hunt tests (These are FUN! they even have a junior handlers class which I think you would really enjoy)
And lastly just Pugs said earlier, just because a dog is beautiful doesnt make it a show prospect, it has to conform to breed standards in terms of height (not much leeway), coat color, even teeth alignment.
And as for me leaving my male intact- I can handle having a responsible household. He is never off-leash in the public parks, he is not allowed to roam freely (unless he is on a long retrieve during training), he has a 10ftx30ft kennel, and I am currently working on constructing a full-length roofing for it, one for added security and for added comfort for the dog. (He has a dogloo that he uses for shelter, but I feel he should have more). But because he is too rambunctious to be a house dog he stays outside a majority of the time, therefore he stays in his kennel, which stays pad-locked when I am not nearby for his safety.
Use your youth to gain experience by possibly working under someone who currently shows conformation dogs.
Good luck,
