With the modern rise of corporate agribusiness and the decline of localized family farms , many breeds of sheep are in danger of extinction. The Rare Breeds Survival Trust of the UK lists 22 native breeds as having only 3,000 registered animals (each), and The Livestock Conservancy lists 14 as either "critical" or "threatened".    Preferences for breeds with uniform characteristics and fast growth have pushed heritage (or heirloom) breeds to the margins of the sheep industry.  Those that remain are maintained through the efforts of conservation organizations, breed registries, and individual farmers dedicated to their preservation.
While nothing is worse than bad things happening to our children, when we dream about this it often has more to do with ourselves than with our kids. If you were failing to protect your child in waking life the dream could be a warning, but if you already are very protective perhaps the dream is about how you felt out of control as a kid and now as a parent still feel out of control to fully protect your child. In this way the dream also just reminds you just how precious and how much you love your child. Sometimes we have a dream like this when our child hurts our feelings or irritates us; in such cases a dream may be a way that our unconscious negative feelings come into consciousness.
