==Description==  

The most common disease of the anal sacs where the sac becomes impacted by a viscous, grey-brown secretion.  It is caused by a failure of the sacs to empty normally during defecation, obesity, poor muscle tone and generalized seborrhea. The retained secretion can encourage bacterial overgrowth and therefore infection and inflammation.
