Deliverance of Breeding Commitee of the Club of Czechoslovakian Wolfdog Breeders to listing crosses between and German Shepherd and a female Canadian wolf in special register of the Czech-Moravian Cynological Union pedigree register


Based on a complaint lodged by Mr. P. Hanuška to the board of the club, concerning registration of crosses between a German Shepherd and a female Canadian wolf, we report:

At our breeding commitee session of 1997, we were trying to find a way how to reduce hip dysplasia in Czechoslovakian Wolfdogs. The opinions referred in specialist literature vary on its causes; however, genetics is considered to play a large role (60-80 %) in the development of this defect. No methods have been set to reduce hip dysplasia so far, except genetic measures. Accordingly, the breeding commitee has focused on genetic influence. Genetic control in dog breeding has not proved effective, though. E.g. in German Shepherds, hip dysplasia has been studied since 50 years, without any improvement yet. The breeding committee nevertheless suggested to reduce breeding in animals with a high-grade dysplasia: a positive bitch cannot be serviced by a positive dog, and vice versa. As a perspective measure, we suggested to build up a selective breed, based on negative offspring from negative parents. In accordance with breeding regulations and with competence of the committee, we have decided to compare wolf hip joints with Czechoslovakian Wolfdog ones and – if the wolf hip joints prove negative for hip dysplasia – to attempt to service a female Czechoslovakian Wolfdog by this wolf. The aim was as follows:

If the crosses satisfy conditions of the standard for Czechoslovakian Wolfdogs, they will be judged at the breeding valuation and bonitation and will take part in Czechoslovakian Wolfdog shows, both club and special ones, out of competition. For this purpose it was agreed in advance that these crosses will be listed in special register of the Czech-Moravian Cynological Union pedigree register.

Members of breeding commitee will look after crosses of the first F1 generation at their own expense, to avoid misuses. As concerns crosses of next generations, experienced breeders of our club will be asked for taking care of them.

At the age of 12 months the crosses will be X-rayed for hip dysplasia. The X-ray results

should prove or disprove the wolf dominance in transferring negativity for hip dysplasia. If proved, we will continue in breeding with Czechoslovakian Wolfdogs and watching over hip dysplasia up to F4. In case of failure in F1-F4, the experiment will be stopped.

In case of success in F4, breeding commitee will suggest that the board of the club would apply for permit to regenerate Czechoslovakian Wolfdog by these registered crosses.

We have been aware that this challenging experiment is very time consuming (10 years or more), and that in case of success, pedigree of the offspring bred from these crosses would have an enhanced ratio of a wolf.

For this purpose, Mr. Lakatoš's wolf was X-rayed and his hip joints were judged by Dr Šterc as ideal. At the breeding commitee session we agreed on continuing in this experiment with the original aim. Mrs. D. Matušincová offered her breed bitch, but there was no mating. Another attempt with Ing. K. Hartl's breed bitch failed too. In the first case, the wolf didn´t interest himself with the bitch, and by the next rut and attempt at mating, he bit her. Another attempt with Mr. Jindřich Jedlička's bitch was made in the Vyškov Zoo, but without avail. The Prague Zoo refused to take part in the experiment: they did not permit to X-ray their wolf, and required that the bitch to be mated is in quarantine for at least 3 weeks. Meantime we have got another wolves X-rayed, namely in the Plzeň Zoo, with the help of Mr. P. Hanuška and Mrs. M. Šimůnková, and these wolves' hip joints have also proved ideal.

Since mating a Czechoslovakian Wolfdog bitch with a wolf didn´t take, there was nothing to publish.

Mr. Hrach informed us about his succesful attempt at mating his Canadian bitch wolf with his German Shepherd without pedigree. Mr. Hrach's dog comes from a police breeding station, he has passed all training exams and he even won a police dog competition. He was X-rayed and has proved negative for hip dysplasia. The mating was succesful and gave 2 dogs and 2 bitches. One dog died and the remainig puppies were offered for the study of dysplasia.

We accepted Mr. Hrach's offer as a chance to give effect to our original plan to study the wolf dominance in transferring negativity for hip dysplasia. One of the bitches is in care of Mr. J. Jedlička, the other one is in care of Dr. Ing. N. Šebková from the University of Agriculture (with ideal conditions for pursuing the aim). Mr. Hrach is in charge of the dog. Because he hadn't a breeding station, Dr Ing. N. Šebková agreed to list this litter in register of the Czech-Moravian Cynological Union pedigree book at her own breeding station as an experimental litter. The register lists dog breeds not recognized by FCI and experimental litters. We believe that listing will allow the breeding commitee to monitor the crosses as regards hip dysplasia. If they were not listed, uncontrolled crossing could occur, and such crosses would bring no benefits to kynology. We also have considered that anyone else could list these crosses in the UCI pedigree book (UCIanother international cynological organization, competing with FCI) and continue in breeding them.

We have been always conscious that the problem of regenerating any breed of dog is subject to FCI regulations, and these are to be followed in this case too. As the experiment is at its very beginnings and first of all it should help us clarify the question of hip dysplasia and possibility to restore the breed, we did not deem necessary to inform the board of the club. For this reason, Mr. Hanuška's (and according to his opinion, also some club members') fear that current crosses could be put to negative use in breeding Czechoslovakian Wolfdogs is considered faint.
