There are some genetic scientists that are dog breeders...
We are lucky to have one in my breed, and shown successfully & bred Champions too :)
He even did some research in our breed re champions and found that you
didn't need to lose breed type and have to line/inbreed to produce a Champion.

Thing is today we may have to adjust thinking if we want our breeds to maintain health.
By inbreeding throughout breeds if health problems do occur you are stuffed if you don't
have the genetc diversity to be able to breed out/breed away from health problems.
Today my breed is not as genetically diverse as it was when I first came into it over 20 years ago.
It worries me greatly as the breed is fairly well bottle-necked with just a few studs and their progeny
getting the majority of studs in the show fraternity. When trying to look for studs to use and also trying
to steer away from lines that you are aware carry health troubles for eg in my breed cardiomyopathy
there aren't many lines left available to consider. When you are also trying to correct/improve upon certain 'faults' and hang on to the positive attributes that your bitch/dog has.
Until all health problems have a gene/dna test in all breeds it's going to be a nightmare in breed gene pools that
are narrow.
