so, I will tell you a story about HD examinations: one Xray was examined in CzehRep and got HD/C...the same Xray was sent to Poland and got HD/A, the same xray was sent to Slovakia and got HD/A and this xray was sent to my vet and got HD/D!!!!!!After this case no worth to talking about Hd results......

You are making several mistakes here.
No let's talk about it. People please share your experiences if you have strong different HD results from different country. I would be very astonished that there is a country very different from another. Another problem is the focus on the letter, does the dog has arthrosis, does the dog show passive laxity, regular bones shape, coverage trouble ? I can assure you that a hip with HD-D really shows troubles visible for almost any vets, so mistery...
Another problem is focuses too much the dog result as the pedigree analysis is very important, breeders argues that this dog is A this one is B, no problem mating them ! But checking the HD of back-relatives and back-back-relative are almost all non HD free, so yes statistically there is a real breeding trouble here. Intrinsic A has not the same value as some other and this should be in the equation. But people are puzzled, because it jumps generations, and it's "only" probability etc... HD probabilistic model just works, so worth making a deep care on that point.

Another things: inbreeding and linebreeding is not the same...and please write me what is your problem with my consaguinity? Have I got ill dogs? Are my pups die very early?Have you got any other defects? More than from other breeders? I think no........and why write that I use always high consaguinity? I couldn't see strong relativities inbetween Geri and Demon or Quenno and Demon, or Ali and Rubin or Argo and Queety and I could continue.......
I breed for my taste,for my fun.....and fortunately there are a lot of people who like my dogs!!!!

COI between 15% and 20% on five generations is a strong consanguinity, especially if we want to have a global politic/view large scale for this breed. Another error breeders make is to check only for 5 generations, but almost any "non consanguinity" mating in this breed is in reality around 20%, and so some of your mating (not high consanguinity for you) are indeed 40%-45% COI ; this means that for all the dog genome (around 22000 genes I guess) it's statistically more than 9000 possibility for an allele to meet its counter part (remembering that 3/4 of genetic disease comes from recessive trait), this is really too high... and really not needed, nowadays we can, and have to, breed differently if we want not dark future days...
