The AKC is a good registry but they can not govern the whole breeding communitys to better any breed.
Thats why its so important you find a breeder you feel comfortable with, has some knowledge in the breed and truly tries to better the breed. There are many areas in a certain breed to work on.....health, outword appearances, personality.
I think serious breeder try to work on them all.
Thru history I ve read in breeding the 'cream of the crop' is acceptable.
I outcross breed but would inbred if with research and matches looked right.
Right now I wouldnt do it though. I just dont have the matches or enough knowledge. Im learning. Breeding is very hard work.
Breeding is an art.
You either make a stick dog or a pecoso
