The sacs are lined by anal glands that produce a foul-smelling liquid which normally is released with each bowel movement to let other dogs know who was there. When the sacs fill, the uncomfortable swelling causes the dog to lick the anus or scoot the behind on the ground in an attempt to empty them.
