OMG you people are so polite. I am inspired to try to type this as politely as possible. it will be very hard. But sometimes beating around the bush isn't the way to protect the breed.
Good breeders, responsible breeders, do not sell puppies without limited registration (ie must be spayed or neutered) unless they feel the puppy truly is show potential and the HOME knowledgeable and willing to do things right. Keeping co-ownership is common to make SURE it is done right before the concept of breeding ever is done.
A good breeder educates their potential puppy homes. It sounds like you called GOOD breeders who offered you pet quality puppies but you wanted one you could totally control. I understand the desire, but understand a GOOD breeder feels responsibility to their dogs, NOT YOU, in doing what is right.
I would never, in a million years, have sold you a puppy without co-owning or on limited and insisted on mentoring you along if you really wanted to get into showing. A GOOD breeder really would love to have you learn from them and help you. But they would have held onto controls to protect that puppy.
Please, back up. Forget breeding. Get books on pedigrees, genetics and find show mentors who can help you learn to show and understand what you are doing. It isn't likely your puppy is special enough to warrant breeding. But she can be a superb learning tool and fun while you learn the things you need to know so that the next puppy has all the potential. I say that without looking at the pedigree because frankly, when experts here know dogs 3 or 4 generations back, it reveals as much as anyone needs to know. Well that and the ad for these puppies.
My dogs both have NOTHING but champions in every single generation for 5 generations. Guess what, got championship on Sayblee, spayed her. Spayed the other. Why? Because even with great looking pedigrees (and your pups doesn't come close), not all dogs should be bred. Improving the breed means taking a hard look at what really is improving. It also means setting aside your own wants for the benefit of the dog and breed. Did you know that not spaying this puppy before her first heat increases her chances of cancer? Do you know how much it costs to do it RIGHT, from titling, testing, finding the RIGHT stud with titles and tests?
There are many fine good breeders here. I know Rottweilers, rottie lines, rottie genetics. I can look at a pedigree going back 40 yrs and tell you issues. I can't do that at all with Basenji. So I leave the breeding to those folksā¦ even though I am very very very knowledgeable about canine genetics and disorders in general.
I know you dismiss people who say don't breed. So I am sure this post will be dismissed. But I hope not. I hope you start reading to LEARN, open yourself up to being totally responsible about the breed, and if you are set on breeding, that you start putting away the major funds you will need to buy a quality bitch and do it right. And just have fun and learn on this puppy, or spay her and start taking handling classes, hanging out at shows, find a mentor and really learn. And btw, I took 2 1/2 yrs to buy my first Rottie. And I still made mistakes, big ones. But now, with the internet, there is no excuse for not learning and understanding what puppymills, backyard breeding and irresponsible breeding is and choosing to NOT be part of those folks.
