Most good breeders, no matter the incentive given puppy buyers, cannot control people and have the pups produced ofa at 2-4 years to find out results, most normal pet owners dont want to do it, not interested, dont have time for it, what have you, even with a 200$ refund given many opt out of it.
so the information still is not exact even though intentions are.
keeping this in mind, the growth plates on some newfs they are finding are not closed until 3 years of age, wich i believe is the time to do final clearances on them, once it is all done.
but one never knows for sure.
breeders will do their best to keep track, and encourage/remind pet owners to do their ofa, with incentive there hopefully they will follow thru.
I also would add
there is no known true formula, any litter of pups five or more, will have one or two displastic pups produced no matter the research no matter the clearances, it is my belief that the gene is so polygenic it will never be pinned down, if it can be, great! think what they could do for humans suffering from the same conditions, i also dont believe in limiting the gene pool so much becouse that leaves them open for other nasty things cropping up.
just my own humble thoughts, speaking as one who still is researching, learning, and sharing with other breeders.
many pets are raised in unoptimal conditions, no excersise leads to lax hips open to displastic conditions, muscle pulls in the bones, muscle is the building block of any dog, if they are lacking in it, they wont turn out nice.
i am not so convinced that CHD is strictly genetic and again it is my humble opinion.
