When an animal has a bowel movement, the anal sphincter squeezes the anal sacs against the feces causing the sacs to expel their contents onto the fecal matter. This action typically (and thankfully) goes unnoticed by pet parents. Their actual purpose remains unknown, but many believe that anal gland secretions give feces a unique scent allowing animals to use it to mark their territory. One of the questions that people frequently ask me is if people have anal sacs. The good news for those pet parents worried about having anal sac problems of their own is that fortunately, humans do not.

Signs and Symptoms
If your pet develops anal sac problems, you may notice that your pet is “scooting” (dragging their bottom on the ground), licking excessively under their tail, or you may notice blood or discharge around their anus. You may also smell a foul pungent odor.

Diagnosis is made by digital palpation and treatment involves manual expression of the anal sac contents. If they are infected they may be flushed and your pet may be treated with antibiotics. An abscess will probably require surgical drainage and antibiotics.
Anal sacs problems are fairly common in pets. Fortunately, most anal sac problems are not serious and are more of
