Lately I’ve encountered many dogs owners that are complaining that their dogs are scooting
their rear end across the floor or even more annoyingly- the carpets. Scooting has two main
reasons. It can be caused by presence of intestinal worms or more commonly due to anal sacs
Dogs and cats have a pair of glands that are called anal glands or sacs. These are scent glands
in nature. The glands are located in their anal sphincter muscle, at the 4 o’clock and 8 o’clock
positions. A tiny duct or tube leads under the skin to an opening directly beside the anus.
These glands produce and store an oily liquid material that is used to mark territories. When
dogs greet each other and sniff each other rear ends, that is what they are smelling.
The anal glands content has a very foul smell even when the glands are healthy. The anal
glands empty through an opening in each gland with stool passage in the rectum.
Spontaneous release of the anal glands content is also associated with fear and in stressful
Anal glands disease is a condition in which the glands are not getting drained, the content
accumulates and get thickened which further prevents the drainage of the gland. The gland gets
infected and may eventually form into an abscess ( a pocket of pus) and if left untreated may
The most common symptoms of anal glands disease are signs of discomfort: scooting, licking
and biting the anus, and chasing the tail. This condition is much more common in dogs than in
cats. If it does occur in cats it might be manifested by defecation outside of the litter box. If you
notice one or more of these symptoms take your pet to see your veterinarian. The veterinarian
will attempt to empty the glands manually and will evaluate the nature of content acquired. The
anal glands content is normally a yellow to tan in colour liquid. Impacted anal gland material is
usually brown or grey and thicker. The presence of blood or pus indicates infection. If the
content suggests presence of infection the veterinarian will prescribe systemic Antibiotics.
Flushing the glands and administrating local Antibiotics and Anti inflammatory drugs is very
effective for treating anal glands disease, but this procedure requires sedation or anaesthesia.
The main goal of the treatment is to clear the infection as early as possible and prevent formation
of an abscess and rapture of the gland. Occasionally the problem can be chronic and very
disturbing to both the dog and the owners. In severe chronic cases a permanent surgical
excision of the glands might be recommended. This procedure is not risk free, hence is
recommended only when a routine medical treatment has failed.
Prevention of anal glands impaction and infection can be made by periodic check ups by your
veterinarian. Frequent emptying the glands may assist in preventing impaction and infection.
Emptying the sacs when not impacted is a very easy and quick procedure, but it needs to be
done by a professional veterinary caregiver.
Feeding the pet a high fibre diet may be beneficial in prevention of the condition by producing a
bulkier stool that presses against the glands in the process of defecation, and helps their normal
