They are pockets which vary in size depending on the size of dog and presence of any disease, and have small openings towards the opening of the anus. These sacs tend to empty their contents when a dog passes faeces. On occasion they can spontaneously empty when a dog barks or jumps, or can even do so without any sudden activity, expelling their liquid and scent to the outside. The anal sacs can become problematic for several reasons :.

The rear end will be extremely hot, swollen and painful.

For most patients this is an uneventful natural act, but for others, they may experience blocked sacs where the secretions get trapped and cannot escape via the duct.

The sacs are lined with numerous specialised sebaceous skin glands that produce a foul smelling secretion. Each sac is connected to the outside by a small duct which opens just inside the anus. The secretion acts as a territorial marker. Normally they empty when the dog defaecates.
The obnoxious substance coming out of the anal glands is supposed to help dogs mark their territory when they defecate. In reality, anal glands can cause all kinds of problems in dogs and occasionally in cats. They can get blocked, infected or even turn into cancer.
