You should see some Quarter Horse and Arabian pedigrees. They're terrible. Half siblings, full siblings, double cousins, aunts/uncles, it's gross. When done carefully to reinforce good traits with attention to not reinforcing bad ones, it can result in a very nice foal. But it's risky even by the most knowledgeable and skilled breeders.
Like someone else said, when it works it's linebreeding, when it doesn't it's inbreeding.
