All i can say is Wow.

Happens pretty frequently among AKC folks. It "fixes" type. As long as you know your lines, you are safe. Inbreeding is like a magnifying glass - it will double up on good as well as bad genes, so if you have bad recessives in their, they are more likely to crop up. But it will also make your "type" prepotent in your breeding program.

I would be to scared to fix anything with that kind of breeding. I would never feel prepared enough for this breeding.

Line breeding this close is OK as long as you have did your homework on your dogs ancestors. You always need to do your homework when breeding to make sure the desired traits are brought out in the puppies. I would only recommend this type of breeding with strong dogs that has no genetic defect.

I actually have 2 dogs that are out of a father-daughter and a mother-son breeding. Both breeders who did the crosses were very familiar (20+ years) with the lines in question. Both dogs are very healthy - one is an 11 year old Rough Collie who has been tested for everything and is clear. The other is a Finnish Spitz and so far they, too, are healthy
But if you do not know every little detail in your lines, it can be disastrous, and you really need to commit to cull puppies...

Thank you, Casa del Mango for proving my point about doing your homework.

I have a cure for that: it's called : LIMITED REGISTRATION

If you are breeding dogs like that on purpose in your reputable kennel then

Go for it, I just think there are quite a few GSD's out there to pick from,

notice there are only 3 pups in the litter,

maybe mother nature is watching out

Yes, typically the inbred litters are smaller than outcross litters. Breeders and geneticists often do breedings like this to "see" what really lurks in their lines - test breedings. This sort of thing revolutionized medical research with things like Jackson Lab's "Onco-Mice" (specifically designed to be prone to different cancers so that scientists could study cancer and save human lives)...

As an aside, parent-offspring breedings do occur in nature, too. We humans apply morals, Mother Nature doesn't. She only corrects mistakes. There are some species populations that are so insulated there is not choice but to inbreed at this point.
