"In-breeding", or line-breeding, has been done for hundreds (thousands?) of years in animal husbandry to achieve desired traits. Name a domestic animal species, and even some zoo breeding programs for endangered animals, and you are sure to find these types of practices. That's not saying it doesn't have its risks but, as MrV said, when done carefully, with a well thought plan, it has great rewards.
I'm not a breeder, but I've been interested in animal breeding practices since before I started looking for my first dog over 11 years ago. My breed is the Standard Poodle, and this is a hot topic among Poodle breeders as well so I've heard all of the arguments many times over.
