"Tremors are caused by the synchronous contraction of reciprocally innervated, antagonistic muscles, leading to a regular to-and-fro movement in all or part of an affected dog\u2019s body.  The underlying cause of tremors is often unknown (idiopathic).  Tremors generally can be related to genetic or developmental conditions, trauma, compressive lesions of the spinal cord, inflammation, exposure to any of a number of tremorgenic toxins, poor blood perfusion to pelvic muscles due to cardiac disease, immune-mediated diseases, metabolic diseases and degenerative diseases of the nervous system. Certain breeds appear predisposed to developing tremors, and certain medications can induce tremors.  There may be other causes as well."^^<http://www.w3.org/2001/XMLSchema#string>
