2-2 linebreeding allowed by the SV? - Page 1

Breeding half brother ans sister too close?

interesting question

It is too close for my taste, but permission is sometimes granted even by the S.V.. It is of course something that must be approved in advance and I understand difficult to obtain.

In my opinion this type of breeding should only be done by a very experienced breeder who knows the risks and possible rewards. These days a half brother x half sister is a bit unusual, as it is more common to see a sire x daughter mating.

Bob-O I agrfee with you.  The other thing is to positively know the dogs in the lines you are using because yoiu arer either going to get the best or the worst.  You might want to try searching for Planned Breeding by Lloyd Brackett to learn a lot more about inbreeding.

This example is from the mother of Yimmy van Contra.  If I am not mistaken I think, 2-3 is as close as the SV allows you to breed.  I heard of a lot of grumbling at a show over there, that Yimmy would not have even existed under the SV rules if the country that he was bred and born in, adhered to the SV protocol of inbreeding. 

Wish this board still had the large number of Germans contributing, that it use to.  Someone could certainly clear this up.  Unfortunately, I think most of them have left, do to the bickering that has become prevalent, here.

I did not know that about Leah. 

Thanks

To the best of my knowlege, the SV will register register a litter from a 2-2 breeding under special circumstances--say, an accidental, but proven, breeding from a brother and a sister.

Bob, I respect your work on this board but it is not comparable 1:2 mating (father:daughter) with 2/+:+/2 combination (half brother with half sister). Half-brother and half-sister is not through 2:2 combination like brother:sister!

1:2 is the biggest risk and my opinion is that breeder of that combination must leave progeny under his control and breed them under his control in next minimum 3 generation because he must wait to see what will be with genes after few generation. He could not put dogs from that combination on market without control as breed could get big damage if someone start to breed specimen out of that combination with great intensity because of phenotype but descendents genotype in next generation and generations could be unrecoverable damaged. That is serious experiment and breeder must be well educated, experienced and prepared for that game. Genes from very close combinations are not stabile for next few generations.

You must have two good specimen and you can write your request on paper to SV and they can permit or not your idea. You must have great explanation for your work in that case

All breeding GSD are based on line breeding concept through many generations and every closer breeding of 3:3 is much greater risk then similar combination with some other dog breeds. My opinion is that is time to start to involve new alternative blood out of relatives in first 5 and more generations in our breed programs and then we can continue "cleaning" with line-breeding, maybe with some other much complicated combinations.  We concrete uniformity, but with every new generation every fault will be much harder to resolve as we in every new generation based on line-breeding, we concrete same faults, too, because we have not got perfect dogs in our breeding programs. Perfect dog is not born jet!

So, I expect that we will have very, very big problems in breeding GSD in nearby future.

Bob-o,
What's closer?
Half brother to half sister or sire to daughter?

I had a lab one time, as I was checking her pedigree,
I noticed her sire was her half brother, she was a very
good looking girl!
Very pretty and good conformation.

Although, she was afraid of the inner tube tire floating in my pool!

Strange.........................

And, Amir, I understand what you are saying, but, two good specimens,
could mean a bomb waiting to explode.

Stephen,
That's one nice looking dog..............
