History and Clinical Signs

  • See Anal Sac Disease - General
  • The sacs are painful
  • Fever if the sacculitis is severe

  • Mild antiseptic solution such as 0.05% chlorhexidine.
  • Following flushing, antibiotics should be used either systemically or topically (with or wothout the use of a corticosteroid)

  • May require anal sacculectomy of which an open technique is preferable
