There are few things more enjoyable than watching a herd of young horses frolic around a pasture. But when one of the foals looks shaky, incoordinated, and almost wobbly on his feet, this could be a sign of a serious–and sometimes fatal–neurologic problem: cervical vertebral stenotic myelopathy, or wobbler syndrome.
