If something is worth doing it is worth doing well. Additionally because your dealing with living breathing beings and also bear a responsibility not only for any lives produced but also to the prospective owners, this holds doubly so for breeding.
There can be no legitimate excuses for cutting corners, especially when it comes to health.
As your girl isn't Kennel Club registered I would not breed from her at all.
You have no way of knowing if her pedigree is anything other than a work of fiction, and it certainly will not have any health record history for any of her purported ancestors.
To breed responsibly and to have the best chance of breeding healthy pups you need not only to health test the bitch and use a health tested sire but know of the health of the generations before.
Most bad genetic traits are recessive, that means they often are not apparent in the dogs being bred from but are carried from generations before and two copies of a bad gene are needed, or combinations of bad genes.
Unless you study the ancestry you won't know any of this.
To do so most reputable breeders belong to breed clubs who monitor the breeds health and advise breeders and owners. The only real registry for pedigree dogs is the kennel club, even they don't demand health tests, but certainly encourage their use, any other registry is just interested in the commercial production of puppies and supplying documents to make them seem more than what they are.
I would advise you spay your girl and enjoy her as a pet.
Fro the price of the health tests alone you can very nearly purchase a well bred puppy as a companion from her.
Pleases go through one of the breed clubs and choose a responsible breeder who has generations of health tested stock behind the puppies they breed and will be there to help and guide you in the future. You never know you may then if you find your bitch is good enough breed once you have gained the required knowledge, and with a firm foundation of a well bred bitch with people who know and care about the breed there to guide you.
The best breeders will tell you it is rare for their first pet to be the quality to be the foundation for their line and, when they did breed from an average specimen ti took many generations to improve the quality.
Why not take your bitch to either gundog or show training classes and have a go at working or showing her, and learn more about the breed while you go on the waiting list with a good breeder for a quality puppy. Attend shows or working days and join your local breed club.
You will then have a head start with the new pups in whichever side of dogs your interested in getting involved in. Breeding should be a by product of showing or working your dogs.
