Anal sacs also referred to as anal glands are a pair of glands just under the skin adjacent to a pet's anus. The anal sacs fill with a foul-smelling fluid that's normally expressed through tiny ducts during defecation. Though dogs and cats have historically used their anal gland secretions to mark their territory, our pets often express these glands when they're anxious or frightened. Anal sacculitis is a term reserved for the frustrating condition characterized by the inflammation of these anal glands. Pets so affected experience a build-up of fluid in their anal sac, an uncomfortable condition that can lead to pain and itching.

When a dog's anal sacs are swollen and inflamed they are treated by draining. Draining is done manually or surgically with a scalpel and under anesthetic. When done manually, the procedure is called anal sac expression. Dog anal sacs are emptied manually either by external or internal expression.
