I’m not sure how the OP can define herself as “responsible” since she appears to have broken the rules:
the breeding stock must be proven- depending on the breed of course, but the parent MUST be either actively working and can be proven to be a good worker, or have titles of some kind from competition. I personally don’t think having ONLY conformation titles proves the dog is worth breeding- a dog should have both conformation titles and some kind of performance titles; if it’s not a “performance” type breed and is instead a “companion” breed, then something like passing a therapy dog test or the ATTS temperament test would be nice. I don’t believe conformation titles prove the dog has a breed-appropriate temperament or breed-appropriate drives/behaviors.
The breeding stock must pass all the necessary health checks for the breed’s genetic problems.
The breeding stock must have an excellent breed-appropriate temperament (this is somewhat subjective obviously, but if say the dog is supposed to be a high-drive high-energy intense breed and the dog is instead laid back and lazy, that’s not a good choice for breeding).
The majority of the breeding stock’s relatives (ancestors and siblings) should also be able to pass the above three tests.
Buyers are lined up before the breeding occurs. If the breed usually produces 12 pups per litter, you probably want at least 15 buyers lined up waiting.
Breeding for “pets” should never be done deliberately, because even the best, most careful breeders usually end up with some “pets” in their litters- so they can place the performance/show dogs in proper homes, and then place the “pets” in pet homes.
