Dharkwolf - thanks for interestng insight. I agree with you that the endurance test does not substitute the HDD test. But on the other hand, it can show you, what the results of the test really are.
HDD A dog may not be able to complete the run because it is kept in cage all its life, no stamina etc. because of the owner... On the other hand, if a dog has HDD C, has completed the 100 km run twice in his life and in 9 years of age is still healthy without problems with hips, it also tells something - that either the tests are too stringent, or that the reason for the mark is not reaaly causing problems in dogs (if they are trained properly). Now you can speculate on the training, but it is well know that both too much training and too little of it are not good for health not only in dogs.
Therefore I think it would be very interesting to study the correlation in different traits of the HDD (as for example the angles etc. - please note that I know about HDD only what I found on these pages in discussions, so somebody else should say what traits can have different effects) with development of the problems and in what age are they developed and if it can be somehow affected by training and then consider these results for further breeding.
