Lot's of good information already on this post.
Let me explain to you what these folks are trying to tell you.
How close you can breed, and how many times you can "get close" without "bad things happening" are a result of how sound your breeding stock is.
Example...let's say that back in the second generation of your half-brother X half-sister cross, there is a dog that had seizures. Now you don't have any way of knowing that...but it did. If you breed those two ancestors of that dog that had seizures, you are more likely to get pups that have seizures....if you breed that next generation of pups together, again in a half brother half sister fashion...more of your pups are likely to be born with a seizure disorder....
So basically, if you want to find out what kind of genetic skeletons are hiding in your closet...linebreeding and inbreeding are a good way to find them. However, if you are line breeding, you are not introducing buggymen into your genetics....you can't "create" bad things, just uncover them.
On the other side of the coin, by outcrossing, we just keep burying those bad traits. They end up "popping up" unexpectedly from time to time.....but many dogs may be carriers!
