One of the most common issues our Doctors at Cascade Animal Clinic have to deal with are problems with anal glands. Anal sacs (also called anal glands) are two small glands just inside your pet's anus. The material secreted into these glands is thick and smells foul. Most animals can empty these glands voluntarily for scent marking or in self-defense like a skunk might do.

Domestic animals have largely lost their ability to empty these sacs voluntarily. Walking and normal defecation serves to empty the glands but some animals become unable to empty the glands on their own. The sacs become impacted and uncomfortable. Dogs with impacted anal sacs usually scoot their rear on the ground in an attempt to empty the glands. Some dogs will lick their anal area and other dogs will chase their tails. Cats often lick the fur off just under their tails.

What to do about Scooting?
The first step is to check the anal sacs when a pet has a history of scooting. The anal sacs can be emptied in one of two ways.

  • Externally: A rag or tissue is held up to the anus and both sides of the anal area are squeezed. If the secretion is very pasty, this method may be inadequate to empty the sacs.
  • Internally: A lubricated gloved finger is inserted in the anus and the sac is squeezed between thumb and forefinger into a tissue held externally. The full anal gland feels like a grape to the side and slightly lower than the anal opening. The emptying procedure is repeated on the opposite side. If the sacs have been emptied adequately, the scooting should resolve in a couple of days.

What if Scooting Continues?
If scooting continues for more than a few days after sac emptying, the sacs should be re-checked. For some individuals, it takes several sac expressions in a row before the sacs stay emptied. If the sacs are empty and scooting is persisting, another cause (such as itchy skin, tapeworms, or even lower back pain) should be pursued.

What Happens if an Impacted Sac doesn't get Expressed?
An abscess can form and rupture out through the skin. This is a painful, messy and smelly condition often mistaken for rectal bleeding. If an anal sac abscess forms, your veterinarian must properly treat it. Antibiotics will be needed.

How often should Anal Sacs be Expressed?
This is a highly individual situation. The best recommendation is to let the pet tell you when the sacs are full. If the pet starts scooting again, it is time to bring him in.

What if My Pet's Sacs seem to Require Expression all the Time?
To avoid the expense of having the sacs emptied, you can learn to empty them yourself at home, but most people feel it is well worth having someone else perform this service. A non-invasive technique that helps some patients is a change to a high fiber diet. This will produce a bulkier stool that may be more effective in emptying the sacs as it passes by. In the worst cases, the doctors at Cascade Animal Clinic can surgically remove anal glands.
