More on anal sacs

The anal glands (sacs) are two small tissue envelopes located on the sides of the anus at the four and eight o’clock positions. Specialized glands with their secretions that produce a very strong odor line the walls of the sacs. These sacs open directly into the anus through their own ducts.
Dogs mark their territories with the secretion of these glands.
I see anal sac disease in dogs quite commonly. When the anal sac ducts are inflamed they become much narrower. In result, the content of the sacs cannot be expressed normally.
This is when the sacs become impacted and swollen and make it quite painful for the dog to push the fecal material out of the anus. The impacted material within the sacs provides an ideal environment for bacteria to grow and cause infection. This will even progress to an abscess. Then you will see swellings, redness and severe pain around the anus.
Unfortunately, it is quite common for the condition to recur. This is more common in overweight dogs.
What are the signs to watch for?
The very initial sign is noticed when your dog starts scooting; rubbing his/her back end on the floor. Then they may start licking or even trying to bite their anal area.
If the abscess bursts you will notice discharge of blood and pus and sticking of the air around the anus to the discharge.
If you see any of these signs, please call us immediately. Your dog will need help to cope with the infection, abscess and associated pain.
All the best,
