Really? So you will prefer to breed with dog which is ill and the heriditary of the illnes is higher and the chance of getting ill puppies is bigger. Than with dog where the heriditary is smaller and the illnes is caused in many cases not by genetic but external factors... Weird way of thinking. Sp we should breed dogs with heart problems because the problem is no so common like HD... And breed with dogs with one testicle because very high percentage of offsprings of such dog will be normal?

According to the new researches VERY high influence on the HD-result have the external factors like conditions where the puppy lives, feeding and so on. So breeding with HD-free dogs only will not have big influence on the results in the population. I think better results we will get if the breeders will breed "natural" looking dogs where puppies look skinny like real wolves and not like fat "tanks" which we can see so frequently at the moment /where the hips are overloaded and can not develop properly/.
In opposition to this the ED seems to be mostly caused by genetic factors - as I wrote you can see it in the database that is is a problem of one or two CzW families - ED appear mostly by dogs comming from the same ancestors.

I ask questions to things I do not understand, if it bother you, please tell me and I will stop ! but please stop trying to put stupid opinions on me, ofcourse I prefer to breed with dogs who are healthy(if I were a breeder).

HD C and ED 1/1 are both ill dogs, as non of them are 100% healthy and if one is worse than another, I really don`t know ? If you breed from HD/ED free dogs, HD seems to be worser than ED, when is comes to the result of the ofspring who are effected by this, but on the other hand, when you breed from dogs who are not HD/ED free it seeme that ED is worser then HD, when it comes to the result of the ofsprings effected by this.
Again I must say(with the chance to for this to be deleted in the next qoute), I am NOT an expert !

HD and ED is the same thing in different places of the body, I am sorry but I have never heard of any sientific test who proved that HD is more effected by external factors than ED is ? in fact, the differences between these two illneses I can only take your word for it is true... and as I can see above, your assumptions is not always true !

Hi Rolf. One very short (and maybe stupid) question. Can you buy for you for example puppy from mother with czech HD result D (3/3) and italian B? If this puppy will be health (A or B), will you breed him?

Hi Hanka,
I don`t care from which country HD results is made as I have no knowledge of which countries/vets. is better or worse to make exact HD resuts. When I buy a puppy or choose to use my own dogs for breeding, I leave all questions about health to people who I trust have enough experience/knowledge about this and don`t worry any more about it.

HD D is not allowed to breed in Denmark(I think in all FCI countries?).

It is unjust!
Hanka I like your work and your seriousness, but whenI go to made HD results for my dog, I go to University of Padova (where there are famous and important teachers and studies on displasy) they tell me immediately that she is sure A and than this results go to the ufficial reading central (there are only two central in Italy) and the ufficial results is A.
If what you say would be true, in Italy all dogs will be A or B, but it isn't the real situation! There is also C, D and E.

What dogs did you know that have mistake results?

Hello Serewolf, for me is sad, much wolfdogs is in breeding without HD results. So I think, they have bad HD result. It is not under ENCI. It is bad for breed.
This question what I wrote was special for Rolf

For the moment, all you have to do in Denmark to breed with a CSW,
is to get a 2. place at an international dogshow, nothing more...
So if you don`t make official xrays, you can breed with all CSW`s in Denmark does`nt matter if the dog have strong HD, ED or other illnesses.

I hope to change that in the near future, but things take time !

Rolf...Hanka maybe doesn't speak DIRECTLY but honestly more direct than what is written is quite impossible...
Did you buy a puppy from a female who had HD made in Italy and was B?
I saw the xrays with my eyes, and the Italian documents behind it.
That is enough for me.
According to someone it seems that she had in Czech D(3/3)...

Now I make a stupid question:
HD X rays of czech dogs made outside Czech republic because afraid of results given by Dr Sterc are ok?

Really...I would avoid throwing shit on others (as already mentioned by Edit...) it's not healthy and somehow it comes back to you.
If you doubt Italian X rays (and one in particular) then if we start doubting ALL Xrays made in other countries different than Czech.... you lost your road completely.
I can show you how HD results are given in Italy...I am curious to see the Czech paperwork!

What is written here is very interesting and new to me.
If this is the decision of the administration of Wolfdog.org, let it be (i'm not sooo much against it actually)
But, I kindly ask the Admin if it's possible to write, for more and better knowledge of the viewers, the criteria used to make the list and what makes you be excluded.
Also... could the Admin kindly state if ALL the dogs included in the list have HD results sent to Wolfdog.org (as always requested in the past?) or just ... announced by email from the owner.
Thanks
Massimo

Massimo can translate please?

Definizione scientifica dell'HD:

La displasia dell'anca intesa come degenerazione articolare dell'anca su base genetica è una malformazione coxo-femorale. E' una patologia poligenica e multifatoriale. Poligenica perchè molti geni intervengono nella sua manifestazione, diverse tipologie di controllo genico governano questo poligenismo, dalla comune Dominanza, Recessione, Compenetrazione Parziale o Completa nonche l'Epistasi (fenomeno per cui un tale gene in un determinato loci può influire nel comportamento di un'altro gene in un'altro loci) Multifattoriale perchè la sua espressione è fortemente legata alle influenze ambientali come stile di vita, traumi ed alimentazione.
E' scientificamente provato e riconosciuto che i fattori ambientali possono solo influire sulla modulazione e sull'espressione della patologia. Un cane geneticamente sano non può soffrire di displasia dell'anca per un influenza ambientale. L'influenza ambientale può far si che un cane geneticamente predisposto, manifesti solo un'imperfezione (HD-B, in Italia definita anche sospetta displasia) o una grave espressione della stessa (HD-E).
E' altresi errato affermare che lo stile di allevamento possa generare cani displasici per sola influenza ambientale. Un fattore ambientale nocivo nel cucciolo può in un cane geneticamente sano per quanto riguarda HD, provocare una degenerazione artrosica dell'anca (dovuta a traumi e infezioni batteriche, ect ect), molto simile all'HD per sintomi, ma ben distinguibile nell'esame radiografico.
La displasia del gomito è una patologia più facilmente eradicabile rispetto all'HD, perchè è governata da un solo gene di controllo semplice o Mendeliano, nella fattispecie è un gene Dominante quindi, per le leggi di Mendel, per eradicare un gene dominante è sufficiente eliminare dalla riproduzione il soggetto che presenta quel determinato fenotipo. Ovvero il soggetto che possiede il gene della displasia del gomito, presenta la patologia a livello fenotipico.
Nella displasia dell'anca, un soggetto sano fenotipicamente può avere un patrimonio genetico altamente predisposto a trasmettere la displasia e quindi non è sufficiente riprodurre sulla base del fenotipo dei genitori.
La stima del valore genetico (genetica quantitativa) è il metodo che fino ad oggi ha dato maggiori risultati, ma si basa su enormi e accurati notizie fenotipiche, calcoli genetici e correzioni matematiche atte a considerare i fattori ambientali nell'espressione della patologia.
La nuova frontiera (ne ha parlato recentemente Ina) è una ricerca sui marcatori genetici, o microsatelliti, ovvero delle conformazioni ricorrenti nella sequenza del DNA. Per spiegare in poche parole, questa ricerca non individua i geni responsabili, ma delle configurazioni ricorrenti (ovveri dei "disegni", marcatori nella stringa del DNA) direttamente collegate all'espressione della patologia. E' sempre un metodo indiretto come la stima del valore genetico, ma molto più semplice e più rapido nel caso di un buon numero di campioni di DNA.

- Atti del 1° Convegno Cinoflilo Nazionale 6 dicembre 2008 "La displasia dell'anca e nuovi criteri nella selezione dei riproduttori" relatore dott. Pedrani CELEMASCHE
-Missiva del dott. Vezzoni FSA
-articolo del dott. Asnaghi CELEMASCHE
-"Metodi di Miglioramento Genetico in Cinologia" Università di Pisa Leotta 2004
-"Genetic for Dog Breeders" Robinson 1990

affermare che allevare i cuccioli magri come lupi, sia un metodo di miglioramento nell'incisività della displasia dell'anca è scientificamente errato! Concordo nell'allevare i cuccioli nel modo più naturale possibile, ma non per motivi legati alla displasia dell'anca!

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.

No Massimo, on first i explane than Hips can't be created by external factor, Hips start in any case from genetic heritage...breeding condition's of puppy can't be in any case positive or negative about the genetic's manifestation of Hips. A breeding condition beneficial for animals genetically predisposed do not manifest the disease seriously, is maybe better for the dog and the owner but is negativ for the genetic improvement of the population!!!

Massimo, you are very lazy!!!

Is scientifically tried and recognized that the environmental factors can influence only on the modulation and on the expression of the pathology. A genetically healthy dog cannot suffer from displasia of the hip for an environmental influence. Environmental influence can make that a dog genetically predisposed apparent only an imperfection (HD-B, in Italy also defined suspicious displasy) or a serious expression of the same one(HD-E).
