Anal sacs, also known as anal glands, are two small glands located just inside an animal's anus. These glands empty when pets are marking their scent or acting in self defense, secreting a thick, bad smelling odor.
Domestic animals have largely lost their ability to empty these sacs voluntarily, though walking and normal defecation can usually empty them. Some animals, however, develop problems and are unable to empty the anal sacs. As such, the anal sacs may become impacted and very uncomfortable. The most common sign of an anal sac problem is a dog or cat who scoots his rear end on the ground. Dogs may also lick the anal area in an attempt to empty them or even chase their tails, and cat may lick off the fur from the area beneath the tail. If your pet is exhibiting any of these signs, have him seen by your veterinarian.
If there is a problem, your veterinarian can empty the sacs either externally or internally. To empty them externally, both sides of the anal area are squeezed. If this is not sufficient, they may then be emptied internally by inserting a lubricated and gloved finger into the anus and squeezing the sac between forefinger and thumb. If left untreated and the anal sacs are not emptied, an abscess may form and rupture, which can be a very painful and messy condition requiring proper veterinary care and antibiotics. Some pets require frequent emptying of the anal sacs. Often times, feeding your pet a high fiber diet can help as the bulkier stool that is produced may help to empty the sacs as it passes. The anal sacs can be permanently removed with an anal sacculectomy if emptying becomes necessary every few weeks or so. |
