Natural Selection is nature's fail-safe method to maintain eugenics (good genes and fine offspring). All dogs are different; individual variation is an inherent characteristic of sexual reproduction. Different dogs fair differently in different situations: those dogs best suited to the immediate environment (the genetically fittest) do well; the less fit do less well; and the unfit usually die.
