    Oh. It’s because of selective breeding.
    In general, aggressive selective breeding involves pulling from a smaller gene pool, which results in congenital problems. Wolves breed naturally, so evolution ensures they can survive well.
    It’s basically the same reason we don’t have incest babies. More or less.
