now...returning to the initial reason of discussion, there is still an open question nobody has really answered to.
1) in slovak and czech officially recognized bonitations.
Is the lower height limit of 65cm a STRICT limit under which a dog will SURELY get P14?
I know for sure because I asked Sona Bognarova the lower limit of 60cm is NOT strict for females and they can get a P5 code if 1cm less and everything else is ok.
Is this the same for males in SK? in CZ?
As Oskar Dora is one of the most titled specialized living CSW judges, either the reply is YES for Slovakia or the reply is NO for slovakia and it was an ecception for Poland Bonitation. I suppose there was no special Polish bonitation and it is allowed in Slovakia. Anybody can reply from CZ?
my personal opinion (so it means nothing

) is that they should get P14 but P14 should be allowed to breed in special conditions monitored by the club.
Otherwise 73cm dogs risk the chance not to be born from 64,5cm ones...
I will add just another comment for those who have never seen a bonitation: Height on Bonitation is just the height measured by the judge during the bonitation.
It is NOT NECESSARILY correct, 1 or even 2 cm sometimes are "lost" because the dog is not in correct position and bending down.
The opposite can also happen: If you have a 58-59cm female, it is quite easy to make her become 61cm... I've seen it with my own eyes. It is not correct too, but it saves the dog from being disqualified from breeding (and It is a pity)
I agree with Margo, Px factor is sometimes not good.
Just make a list of defects, disqualifying and light, and result should be OK for breeding or NOT ok for breeding.
