Osteopathy is holistic in its approach and considers the health of all the systems of the dog (including cardiovascular, respiratory, digestive and nervous systems).  By regaining balance in the musculoskeletal system there are also benefits to these systems (both mechanically and through improved nerve and blood supply).  If there are any changes to the structure, the dog may become stiff and exhibit changes in stride length.  This in turn could lead to further damage to ligaments and muscles as the dog tries to compensate.
