Hello,

I talk to a breeder who is going to mate a bitch with a sibling of her sire. This brothers come from an outcross of two linebreeding ( the same great-grandfather from their sire and the same great grandmother from their dam ).

The bitch which is going to be mated to her uncle came from an outbreeding , because the breeder wanted to introduce the nice head and expression her dam had. Now, mating back this bitch to her uncle he expects to improve the type of the offspring that was a "bit" lost when he made the outbreeding.

All the dogs are tested...etc, Do you think this is a very close mating to avoid? Do you think mating the bitch back to his uncle will recover the type of his line but with that lovely head he wanted to introduce ?



Thank you

Sorry for my english :mrgreen:

I am NOT a breeder nor do I know all that much about breeding, however personally I am someone who looks more positively upon outbreeding. I have heard that linebreeding can be done smartly as long as all the dogs are tested and you know the breed/family of dogs inside and out (their history and all). Many cases of linebreeding involving unreputable breeders is a contributing cause to these genetic problems we see in dogs today. Linebreeding with a very reputable breeder is MUCH better than linebreeding with an unreputable breeder. Linebreeding is also a very controversial subject though because of the idea that a dog is conceiving a child with a relative. This would be something really looked down upon in humans, but one must remember that these are not humans, but dogs. I have read that linebreeding can also cause decreased longevity but there has not been much research to back that said fact.

In conclusion, I feel that linebreeding is something that should ONLY be attempted by a breeder who is EXTREMELY reputable and knows their breed/litters inside and out! This will eliminate any possible genetic and tepremental disorders being passed on.

Thank you very much for your explanation Todd , he is a very "concerned" ? breeder about health issues : )

There is a mathematical way of working out how inbred a dog is. It is called the COI - Coefficient of Inbreeding. 12 % is considered a "safe" figure but many breeders prefer it to be as low as 6%. Some show dogs are as high as 25 %.

Well, a concerned breeder and a reputable breeder are not always the same things. Here's some nice info I found online on how to determine if a breeder is reputable. It's a link to a little self quiz to determine it;

*A reputable breeder should have all records of relatives and their joint/health evaluations as well. remember, talk is talk. Make it clear that you want the written proof.

This may help you to better understand as Cigwyllt noted.

Line breeding is very common place among reputable breeders.
It is not something that should be done lightly and without the proper knowledge.

In this case, it seems as though the breeder has a complete grasp of breeding and a purpose for this particular line breeding.
There are some who go as far as to breed father to daughter or half siblings....this is a farther outcross than that example.

If knowledgaebale and the purpose is there, it is a necesarry thing to do sometimes to get the quality in the breed.

Thank you pinsnpugs :-D

I have been reading a lot about the inbreeding, linebreedig , outbreeding ... and it seems the best way to recover the type lost with the outcross is mating to a close relative that fits in the breeder type . The uncle of this bitch has an outstanding breed type , an excellente headpiece and expression too ,so the breeder hopes that some of the puppies will be very nice dogs.

Sorry again, for my english . I can't express myself properly .
