I think New Zealand requires PH (according to the breeders over there I have chatted with). I don’t like plain screening rads as hard /can’t see laxity.. I did plain rads on 2 BCs 10 years ago (neither young and both assessed by radiologist as normal ) and they produced severe HD in the litter (2 pups requiring THR).Really, what countries?
Anecdotal I know but I've collated hundreds of sets of results over the years (including supplying lists of passes and fails to vets who took the x-rays) and I can tell which lines, by now, are going to throw up problems.
Even dogs graded as 'still OK' under the SV scheme, start to show signs of wear and tear relatively young-to-midlife, IME, compared to dogs with 'none' or 'nearly none'.
And it's much more apparent than HD, where dogs with even 'severe' HD I've known, weren't visibly lame until much later in life, if at all.
It's obvious harder with schemes which don't have a cut-off point/the concept of a breeding or competition ban.
I think it’s interesting that we don’t seem to have reduced the incidence of CHD v much by using plain screening rads.. (anecdotally and from what I’ve read, I sure see it just as much as when I 1st started practicing!)
