No...too long!
Use google translator And anyway you explain what was already said by others (Paula's explanation and Admin's one (who the heck is Admin??) was more simple and easier to understand!): elbow and hip displasia are transmitted in different ways. Take away from breeding a dog with Elbow displasia and you have a higher probability to eliminate the problem because it's a Genetic factor while Hips are combination of genetic and environment.

Hereditability of HD: 20% to 40% Herebitability of ED: 40% of 100% Depending of the breed. In easy words, Norberg Angles are the meassure of the angle formed by the center of the femor head with the acetabulum border, those angle is one thing evaluated in the HD exam and different angles results in different HD results. Basically, when more far the femoral head is from acetabulum, less angles it will have, worst result the dog will have. Actually, this metod works pretty well and really helps the selection of the dogs, for sure it will show a displasic dog without any problems as it will show any kind of degeneration already existent, but the polemic of the metod is that the laxity of the cartilage cannot be really evaluate in the X rays, so we can see some cases of females in heath who had receive bad results in the first X rays, and a normal one with nice results about 2 months after it because the hormonal incluence in the cartilages, we also have few cases of very old dogs with bad norberg angles but no damage at all in the femor, but this last one seems to be pretty rare. Remembering that now we have the Distraction metod ( pennhip) which evaluate the laxity, but unhapply its still not avaible for every country like the well know X-ray metod. I think this part already reply you the next one, what is the difference in a HD C dog and a ED 1 dog, as the two are considerated displasic Quote:

...this is wrong...HD ever start from genetic heritage...development of the disease for 80% depend on external factors!!
is a big differences!!!! "...a genetically healthy dog can not get HD disease from external factors.." i must put bibliografy again?

I no moment I said HD was not a genetical illness, but the truth is that external factors make a huge difference in the results, of course a dog without genetic for displasy will not show it BUT nothing impeach this dog to have a subluxation because the place it lives or by accident, wrong feed with wrong exercices can cause artritis, all those cases will be considered displasic in the exams, even if those animals have no dysplasi in their genetic, of course we will not see an A dog turn E because it, but we can see non displasic dogs with B or C. No wonder why we have so many grades for HD. Yes, the dog cant get displasy by external factors, but he can have artritis and artrosis by it, and it will change the HD evaluation on the official results also as a non displasic dog with bad norberg angles. In the same way you can get a dog which have a strong genetic for the problem, but because the threatment it will receive B or C. Well, we have no doubts about how 20 to 30% of genetic can make a huge difference, you can see it principally in the behaviour of working dogs, now you can imagine how much difference it can make when its 40 to 100%.

A harmful environmental factor in the pup is genetically able in a healthy dog as HD regards, to provoke a arthrosic degeneration of the hip (owed to traumas and bacterial infections, ect ect), very similar to the HD for symptoms, but well distinguishable in the x-ray examination.

Arthrosic degeneration can't have influence on dysplasya official result Many people (not you) don't know very well HD from scientific point wiew, is dangerous to say: "Hereditability of HD: 20% to 40%" is better, and more correct to say: "A dysplasic dog inherits his disease from genetic/hereditary way (100%), but the modulation, expression and seriousness are controlled at 60-80% by environmental factors"

Today I have been talking with 4 different vets., one of them is Peter Weis which is a specialist in diagnostics and treatment of joint-/bones-illness and radiography (including PennHIP), he is also member of NOVOS(Nordic Veterinary Orthopedics Society).
They all stated that, HD / AD is both EQUALLY a product of enviroment and hereditary, to proove that one of them have a higher % of hereditary than the other is impossible, as you can not create the EXACT same enviroment for two dogs(even harder with more dogs) to grow up in and further more is it impossible two find to dogs with ABSOLUTLY same genes, which in both cases can make all the difference in the final results. None of them have never heard of breeding from ED free dogs, will give almost all puppies free of ED or that breeding from dogs with ED will for sure give all puppies ED, to me they all explained that the hereditary risks of HD and ED is absolutly the same. Conclution : It makes no sense to exclude dogs with a mild degree of ED and allow dogs with a mild degree of HD, as one is not worser or better than the other. Was this not the reason why Admin made this step, to remove all dogs with ED ? ...aparrently it is for no reason, unless all dogs with HD is removed too ! Please correct me if I am wrong, nobody is perfect Rolf Last edited by Juniorwolf; 26-08-2009 at 21:30. |

If we want to think to environmental influenc with a practical purpose on CZW we need a similar project. Without this we can think only at phenotype (ufficial result) and genealogical relationship on the selection of stud dog.

Another problem with ED is that ED is a term used for MANY different illnesses in the elbow, which is caused by many different things, on top of that in most countries only one photo is used to decide if the dog have ED or not, if done in a effective way, at least 3 photos is needed and many times ED is given for small things who never will have any impact on the dogs life(movement), all depending on the vets. who decide to give ED or not. The expert(Peter Weis) have just bought a German shepherd himself from one parent with ED 0/1 witch I assume(according to his expertise) he would not have done if it really is so bad as some people here want it to be. Statistics of HD for the last 30 years show that in general no more or less dogs have better hips than for 30 years ago, despite all efforts to eleminate dogs with HD worser than HD C ....ED have not even been researched as long time as HD, why jumping to any conclutions seems to be a waiste of time and are irrelevant for the health of our breed.

That is very bad and sad news if it is correct I think the big step against less HD and ED will come first whit the new DNA testing, but until than I think HD and ED x-rays are to be demands for a studdog. Best regards / Mikael

1) The percentage of heriditary of ED is different for different breeds. I found results of scientific work saying ED is more genetic based than HD. And exactly by wolfdog it seem to "work" - the ED problems seem to appear only by the offspring of two dogs. And their lines seem to be "carriers" of the problems.
For some years we allowed to advertise such dogs here but it is visible new ill dogs (with ED) are offsprings of the ED dogs. Other lines are CLEAR. So my question to rolf and Runningwolf: ARE YOU ALSO FO BREEDING DOGS WITH HEART PROBLEMS, EPILEPSY, and STRONG HD (HD-D and HD-E)? Because the same arguments we can use also in this cases... I'm for the these: ILL DOG IS AN ILL DOG = NOT FOR BREEDING Sure you can use them if you want but it is at your responsibility... |

A dog with HD C is in most cases more ill than a dog with ED 0/1, as ED is a term used for many different illnesses in the elbow and many of these illnesss don`t even have slightest degree of influenze on the health of the dog, compared to a dog who have HD C, but you have no problem with HD C, even that it usually have a bigger influenze on the dogs well being ? By the way, why do you put your self higher than the breedingcommitees of the breeds origin ? I am sure if they thought it were so bad, they could easily add this to the standart, but apparently they don`t ? Do you feel you have more experience/wisdom, better knowledge and better judgement than the breedingcommitees of the countries of origin, since you choose not to follow their guidelines ? I`m just curious... Rolf Last edited by Juniorwolf; 03-09-2009 at 13:30. Reason: more text |

...To use your own words : an ill dog is an ill dog. Will it be possible to know your scourse of your claimed seintific work or is it just as secret as who admin is ? Btw. I am still missing some answers from admin on post 49, I`m looking forward to hear what you have to say to these questions. Greetings Rolf Last edited by Juniorwolf; 08-09-2009 at 13:21.

HD-A and HD-B are HEALTHY dogs. HD-A mean excellent hips and HD-B "not quite perfect but healthy". The descriptions by ED are DIFFERENT. ED-0 is for healthy hips. ED-1 is already DISPLATIC dogs with light displasia. Simply said: ED-1 = HD-C (and not like you think ED-1 = HD-B) |
