*The dog and cat posses two '''anal sacs'''. In the dog, these are the size of a hazlenut.
 +
**They are located ventrolaterally between the internal and external anal sphincters.
 +
**The fundus of the sac secretes a potent smelling fluid that drains through a single duct to an opening near the anocutaneous juncntion.
 +
**The anal sacs get compressed during defecation, which causes the fluid to be expressed. The scent of the fluid is thought to act as a territorial marker.
