True, I was more referring to the Germans Shepherds we see which are bred with labs, or other kinds of dogs.
Though that Shiloh are massive , but the ones I have come across do have a nice temperament.
The breeders in Belgian Tervurens are trying very hard to protect that breed from going the way of being mixed.
There is a breeders near me who breeds German Shepherds and when I asked to see the papers as I was interested in buying a couple he refused to show me papers and I found out he has been inter breeding.
I do want another two now my dog has recently died, and it will be a German Shepeherd as great as Belgian Tervurens/shepherds are they are also connect with the Alpha person of the family i.e.me which pisses me wife off LOL.
I will say that, as a breeder, when someone is trying to breed for consistency, they are going to probably try to linebreed because they are working towards a certain goal - the epitome of the perfect dog, in their eyes. Linebreeding is not necessarily a bad thing, especially if they are doubling up on a particularly good dog. Most breeds were created through linebreeding and inbreeding, and of course you can have issues pop up, but even when you outcross from one line to another, that can unfortunately happen as well. With Shilohs, they unfortunately have had many issues, but that’s probably another post for another time, lol.
