Inbreeding in another breed: the Korthals griffon

Version française

After having computed mumerous inbreeding coefficients for Bourbonnais breeders, I realized that one question was always asked: what is the ideal inbreeding coefficient?

Of course, there is no ideal figure, it would be much too simple. But I found it interresting to compare the Bourbonnais to other breeds.

The Korthals Griffon seemed to me a good example because its creation is in fact quite similar to the Bourbonnais one: a breed existing in the form of half blood subjects, reunited to be bred with a lot of inbreeding and establish the type.

My source of information about the first Korthals Griffons was Jean Castaing book, reedited many times: "Le Griffon d'arrêt à poils durs Korthals". The pedigrees of 3 dogs are given in this book, here they are: Partout, Kenau, andPassepartout.

From those information, one can compute all the inbreeding coefficients that I give in the table above. I have computed the average inbreeding of all the dogs in the penultimate line, and in the last line, I ommited the founding dogs, whose inbreeding is in my opinion not significant.

I hope those numbers will help you to have an idea of what is acceptable in term of inbreeding:
