==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.
==Signalment==
==Signalment==
Can occur in any dog of any age, breed or gender however small breed dogs and obese dogs are predisposed. Cats can also suffer from anal sac impaction.
==Diagnosis==
The anal sac region may appear distended and inflammed, on palpation of the perianal tissue may the anal sac may be enlarged, firm and not easily expressed. Impaction can cause tha anal sac to rupture and create a draining tract of either normal secretions (pale yellow) or abnormal (grey, brownor green).

==Treatment==
==Treatment==
Compression and expression of the sacs by either internal or external forces. The sacs are situated at the 4 and 8 c'clock positions. Internal expression is more effective and desired with external expression reserved for small dogs and cats where it is not possible to place a digit in the rectum. If the contents are too dry, then a softening agent or saline can be placed inside to aid clearance.

==Prognosis==
Some cases may require regular expression but generally the prognosis is excellent. Certain cases may become chronic or infected and sacculectoimy may need to be considered.
