Why hip joint dysplasia and crosses


With respect to following discussion on crosses Armín and Lupína, which is being aroused on the web pages by Mr. Hanuska though the explanation of the Breeding Committee was provided, I will try to make another attempt to explain once more the matter of these crosses what Mr. Hanuska considers as the problem.

I am not going to repeat information included in Deliverance of Breeding Committee but as the author of this breed I would like to express my attitude to this matter.

Each breed is going through development in dependence on new genetic and veterinary knowledge in the field of zoology. And so is the case of Czechoslovakian Wolf dogs.

In the time when we started crossing German Shepherd and Carpathian wolf the focus was especially directed to trait of the character of the mating dog, its ability to be trained, its physical constitution, colour of hair and state of health. At that time was nowhere in the world monitored hip joint dysplasia of dogs. The comparison of the crosses was mainly focused on how they digger from German Shepherd – to all intents and purposes of theirs features of character, exterior, health condition, metabolism, resistance to weather condition and inner activity. As a result of increasing proportion of German Shepherd in further generations was found increase of both positive and negative features. The crosses has become observable Langer ears, the quality of fur was decreasing, in few isolated cases occurred looses of the tooth P1. The well known rule that adding the wolf blood (jargon expression of Czech breeding praxis) into NO has its limit and that is why only crosses were mated among themselves. This practice fixed the proportion of the wolf in crosses on 20 % - 30 %. However, high proportion of NO with its insufficiency required very demanding selection which follows to presence.

When having started monitoring dysplasia of dogs´ hip joints, the crosses were also to undergo x-raying. In accordance to at that time valid criteria for establishing the degree of hip joint dysplasia its values (in %) were considerably lower than of German Shepherd. However, this percentage value has gradually began to rise and this tendency continues up to these days, when are applied more restrictive condition which were recommended by FCI and accepted by ČMKU, when percentage value of cases of crosses that are positive cases of hip point dysplasia is approaching the similar level as German Shepherd.

Dogs suffering by hip joint dysplasia of higher degree to II i.e. C are considered as unhealthy and for this reason as undesirable for mating. However the level of hereditability of this malformation is not currently decisively clarified and neither is clarified the effect of further condition of environment for causing dysplasia of hip joint. Not only in this country but worldwide were tried different various ways of decreasing the number of cases of dogs suffering by dysplasia of hip joint, including rejection of all positive dogs and bitches of breeding, usage of medicaments, constraint of movement of puppies, without achieving positive results.

As a consequence we let several wolves to be examined by x-ray and it was unveiled that they do not suffer from hip joint dysplasia. For this reason the Breeding Committee decided for crosscheck of the dominance of wolf in formation of hip joints at new crosses of the wolf and dog. The achieved results were described in the explanation of the Committee. And for this reason were used for their purpose offsprings of bitch of Canadian wolf and Alsation dog. It was considered that Canadian wolf is not a different from the view of species from Carpatian wolf. The possible variation in marking of its fur is not in relation to hip joint dysplasia and the fact that the Alsation dog does not posses identification certificate was not a deciding factor as he descended from breeding brand plant of military service where nursling are not recorded in civic books of pedigree books. The deciding factor was that the dog did not suffer from hip joint dysplasia.

So far not all of the offsprings of this mating have been examined by x-ray for hip joint dysplasia, which can be the reason for lack of knowledge that could be analysed.

Nevertheless, even the pieces of knowledge gained by monitoring the first generation of crosses cannot be taken for granted as the conclusion and for this reason it is not possible to publish them. Besides, this is not done even in other cases of findings of sub-experiments which would lead to demagogy or a fake. If the further generation show a positive findings these results may be used for curative program within cultivation of Czechoslovakian Wolf dog. Suitable Carpatian wolf is not available for this purpose. The advance within such a great interference to pedigree breeding of dogs, according to condition of FCI is known by the Breeding Committee and Mr. Hanuska does not have to indoctrinate in this way.

It was not necessary to inform neither the Slovakia cynological federation nor other cynological authorities for it is only testing experiment that is not directly conected to pedigree breeding of Czechoslovakian Wolf dog.

The reason for the Breeding Committee to enrol the crosses to implemental list of register of pedigree record of the breeding book of ČMKU was explained by its deliverance. The Committee of the club provided unreserved confidence to the Breeding Association. The deliverance of the Breeding Committee is published on the web pages of the Club.

The attitude of Mr. Hanuska to this experiment clearly shows that he did not get into deep understanding of the matter of hip joint dysplasia. I doubt that Mr. Hanuska has achieved such a level of proficiency in the scientific field of establishing the branch and genetics to disregard the work of professionals involved in the Breeding Committee, who have also been active breeders for long time. The exception is Dr. Ing. N. Šebková (member of Club), who is not a member of Czechoslovakian Wolf dog and who was by the unanimous vote elected by the Committee of the Club into the breeding Committee. The reason for this election was to enable the Club to use her knowledge – she has been working as a lecturer at the University of Agriculture for 9 years and her specialisation is cynology. Moreover she is able to involve students into the research in cultivation of Czechoslovakian Wolf dog.

I myself have not read, except from the critical note and attacks to some members of the Club, any scientific text written by Mr. Hanuska.

His aspiration to get supported by its members probably comes from hypothesis that not all of members are well informed and it is more possible to misuse them to his purpose to discredit the activities of Breeding Committee and make damage to the Club´s reputation. He may intentionally also try getting more importance and promote his person and his Club. This idea is supported by information provided by him to foreigner breeders of Czechoslovakian Wolf dog in Slovakia and in Germany who entered a protest against this experiment. They might have been informed in a wrong way by Mr. Hanuska.

I hope, speaking from the point of the chairman of the Breeding Committee of The Club that those club members who takes fancy to Czechoslovakian Wolf dog and are interested in his further upgrading also from the point of health will confide in the Breeding Committee and the Committee of the Club whose intention are especially the duality of Czechoslovakian Wolf dog – not any case of breeding adventure as Mr. Hanuska described from the very unprofessional point of view.
