It depends on the dogs and the personal experience a person has with the family.

If I go out and buy two litter mates, even if they turn out to be good dogs, they may be the exception to their family. If the rest of the family is chock full of curs then when I inbreed I am 're-breeding or re-creating' the rest of the family as much as I am the two dogs that are mine.

At the same time, if you feed'ed you can breed'em.

And if you get good results then it was worth it.

But like any breeding, only time will tell.
