'''Peritonitis''' is defined as [[Inflammation - Pathology|inflammation]] of the [[Peritoneal Cavity - Anatomy & Physiology|peritoneum]].  The inflammatory response involves vasodilation, [[Exudate|exudation]] of protein-rich fluid, cellular infiltration, pain and, chronically, formation of fibrous adhesion.  The disease can be classified into primary and secondary cases.

'''Secondary peritonitis''' occurs as the result of a pre-existing pathological process within the abdomen.  It can be further classified into '''septic''' or '''non-septic''' peritonitis, where septic peritonitis results from direct bacterial infection of the peritoneal cavity.  Septic peritonitis is the most common form in the dog and its causes include:
