Not sick, it's genetics at work. My GF breeds/shows dogs for a living. She has about eight dogs of the same breed, but all show very different characteristics. One is short and thin, one very stout in the upper chest, one taller and thin, one very small and stout of chest, etc. She did not breed to get any of these characteristics, she just chose the one that she liked as a puppy. Dog breeders have a very careful eye for seeing how a dog is going to develop, even newborns. Now say I took the short and thin one and bred it with the small and stout one. The puppies have a good chance of taking on the characteristics of those two. But genetic diversity makes it that I might end up with a bunch of tall, thin puppies, too.
If I cross breeds (which we don't, but I'm hypothesizing) I create even more chance for diversity. Problems, too. But careful breeders within breeds look to avoid those problems. They aren't mad scientists saying "Let's cross a dauschand with a rottweiler."
If I continue to take the smallest dog and breed it (outside of the bloodline) with the smallest dog I can find, there is a higher probability that I will have even smaller dogs over time and generations.
My GF's boss breeds dogs, too. But she has chosen to breed with other dogs with health problems. And a lot of her animals have the same problems. She chose to breed merely for looks and not for health of the dogs. And that, I feel, is sick.
