Can Dogs Express Their Own Glands By Licking? | What That Licking Means

Dogs can sometimes trigger a small anal-gland release by licking, yet it rarely empties them well and can worsen irritation.

If you’ve caught your dog licking their rear and wondered if they’re “taking care of their own glands,” you’re not alone. It’s a common thought, and it makes sense on the surface. Dogs lick when something feels off, and anal glands sit right where a dog can reach.

Here’s the practical truth: licking may squeeze out a little fluid in some dogs, yet it often turns into a loop—itchy feeling, more licking, more swelling, even more itchy feeling. The win is small. The downside can be big.

What Anal Glands Do In Dogs

Dogs have two small sacs near the anus, often called anal sacs or anal glands. They hold a strong-smelling fluid. In many dogs, the sacs empty during bowel movements when firm stool presses on the sacs as it passes.

That pressure matters. When stool is soft, the sacs may not drain fully. Over time, fluid can thicken, the duct can clog, and the area can get tender. Scooting, licking, and a fishy odor can follow.

Can Dogs Express Their Own Glands By Licking?

A dog’s tongue can’t reach inside the sac, yet licking can tighten nearby muscles and bump the area. That can push out a small amount of fluid in some cases. If you notice a sudden smell after a licking session, that can be a clue that a bit of anal-sac fluid leaked.

Still, “some fluid came out” isn’t the same as “the sacs got emptied.” Many dogs lick due to irritation from a full sac, a blocked duct, skin trouble, parasites, or diarrhea. Licking can add friction, spread bacteria, and make the skin raw.

Veterinary references list licking and biting at the anal area as common signs when anal sacs are painful or inflamed. If the behavior repeats, treat it as a clue, not a fix. You can read the clinical signs tied to anal sac disease in the Merck Veterinary Manual entry on anal sac disease in dogs and cats.

Why Licking Often Makes Things Worse

Think about what your dog is doing during repeated licking: they’re rubbing a damp surface, over and over, on delicate skin. That can cause swelling around the sac opening. Swelling narrows the duct, and a narrow duct drains poorly.

Licking can also turn a small itch into a bigger skin problem. If the area gets wet and irritated, yeast and bacteria can take advantage. Then your dog licks more, and the cycle keeps rolling.

What’s Normal Vs. What Needs A Vet Visit

Most dogs lick their rear once in a while. A quick lick after a bowel movement can be normal grooming. A short burst after a stressful moment can happen too, since some dogs release a bit of sac fluid when startled.

Repeated licking—daily, hourly, or intense enough that your dog stops playing or can’t settle—leans away from normal. Pair that with scooting, odor, redness, swelling, leaking fluid, or pain while sitting, and it’s time to get eyes on the problem.

Cornell’s canine health notes describe anal sac trouble, clinic treatment, and the need to prevent licking during healing. Their page is a clear overview: Cornell University College of Veterinary Medicine: anal sac diseases.

Expressing Anal Glands By Licking: Normal Vs. Red Flags

This section is the “so what do I watch for?” part. The goal isn’t to panic at every lick. The goal is to spot the patterns that point to clogged, infected, or inflamed sacs.

Use the table as a quick sorter. It doesn’t replace an exam, yet it helps you decide what to do next.

What You Notice	What It May Point To	What To Do Next
One or two licks after a bowel movement	Normal grooming	Watch for changes; no action needed if it stops
Sudden fishy smell with no skin redness	Small anal-sac leak	Clean the area gently; track if it repeats
Frequent licking for days	Impaction, irritation, allergy-related itch, parasites	Book a veterinary exam, bring a timeline of signs
Scooting plus licking	Full or inflamed anal sacs are common, yet other causes exist	Vet visit soon; avoid DIY squeezing
Swelling next to the anus	Abscess risk	Same-day vet care; keep your dog from licking
Blood, pus, or a hole that’s draining	Ruptured abscess or severe infection	Urgent vet care; do not try home drainage
Pain when sitting, yelping, straining to pass stool	Inflammation, infection, constipation, or other rectal pain	Vet exam soon; ask about pain control and stool plan
Rear-end licking with no odor, plus ear or paw itching	Allergy pattern that can link with recurring anal-sac trouble	Vet visit; ask about itch control and skin workup

What Causes Anal Sacs To Fill Up In The First Place

Anal sacs tend to get into trouble when normal emptying doesn’t happen. Soft stool is a common setup. It doesn’t push firmly on the sacs, so fluid stays behind and thickens.

Body shape can matter too. Overweight dogs may have less muscle tone around the area, and that can reduce emptying during bowel movements. Some small breeds also seem to run into anal-sac issues more often, though any dog can get them.

Skin itch can be part of the story. Dogs with itchy skin may lick the rear more. That irritation can inflame the ducts, and then the sacs drain poorly. A veterinary article in Today’s Veterinary Practice on canine anal sacculitis describes licking/chewing the perianal region as a common sign and notes how recurring cases may relate to allergic disease.

What A Vet Checks When A Dog Keeps Licking

In clinic, a veterinarian usually starts with a full skin-and-rear check. They’ll look for redness, swelling, a clogged duct opening, or discharge. They may also check for parasites, skin infection, and signs that the dog is straining to pass stool.

If the sacs feel full, a trained professional can express them safely. If the fluid is thick, bloody, or pus-like, the plan can shift toward treatment for infection or inflammation. In some dogs, the sacs may need flushing, medication inside the sac, or antibiotics and pain relief.

Cornell’s guidance mentions antibiotics and pain medicine for infections, plus steps to block licking while healing. That detail alone is a hint: licking isn’t a “home treatment” in the eyes of vet medicine. It’s a thing to stop while the area recovers.

Safe Steps You Can Take At Home Before The Appointment

If your dog is licking a lot and you can’t get in right away, keep the plan simple and low-risk. Don’t squeeze the sacs at home unless your veterinarian has shown you the technique and told you it fits your dog. Bad pressure can bruise tissue or force bacteria deeper.

Clean, Dry, And Block The Tongue

Wipe the area with a damp, unscented cloth, then pat dry. If your dog keeps going back to lick, use an e-collar or a soft recovery collar to stop the contact. The goal is to protect the skin until the exam.

Track The Pattern

Write down what you see: scooting, odor, swelling, straining, stool changes, and the day it started. Bring that note to the appointment. It saves time and helps the vet line up cause and treatment.

Watch Stool Quality

Check if stool is soft, loose, or hard. A few days of loose stool can set up anal-sac trouble in some dogs. The UK Kennel Club notes that a lack of pressure to empty the glands, like after diarrhea, can lead to impaction. See their page on anal gland impaction for that mechanism and related signs.

When Licking Can Look Like “Self-Expression”

Some owners notice a moment where the dog licks, then the smell hits, then the dog seems calmer. That can happen. A small release can ease pressure for a bit.

Still, if it becomes a repeating pattern, the sacs may not be draining fully. A partial release can still leave thick material behind. That leftover material can keep irritating the duct lining, then the cycle returns a day later.

How Vets Treat The Root Problem

There isn’t one single fix that fits every dog. The plan depends on what’s found in the exam: thick impacted fluid, infection, an abscess, allergy-related itch, or a mix of issues.

The table below lists common clinic steps and what they’re used for. It’s not a menu to pick from at home. It’s a way to know what your vet might suggest and why.

Clinic Step	When It’s Used	What Owners Usually Notice
Manual expression by a professional	Full sacs with no sign of abscess	Fast odor release; short-term relief if irritation is mild
Anal sac flush (lavage)	Thick debris, recurring inflammation	Less swelling over days; fewer licking episodes when it works
Medication placed into the sac	Inflammation, infection signs in the fluid	Less soreness; reduced scooting as tissue calms
Antibiotics and pain relief	Confirmed infection, abscess, severe tenderness	Better comfort within days; licking drops as pain drops
Abscess drainage	Swollen, painful lump near the anus	Rapid pressure relief; wound-care steps at home
Allergy workup and itch control	Recurring anal-sac trouble plus skin itch signs	Less skin flare; fewer repeat anal-sac episodes over time
Surgery (anal sacculectomy)	Severe recurring cases that don’t respond to other care	Longer recovery; fewer repeat infections once healed

Diet And Stool: The Part Many Owners Miss

Anal sacs empty best when stool is firm and well-formed. That’s why vets often ask about stool quality before they even talk about glands. If stool is loose most days, a dog can slide into repeat impaction.

If your veterinarian recommends a diet change, the aim is usually steady digestion and consistent stool. Fiber can help some dogs, yet the right type and amount depends on the dog’s overall health and the cause of loose stool. A dog with chronic gut trouble needs a tailored plan from a clinic, not internet guesses.

Grooming And Routine Care Without Risky DIY Squeezing

Many dogs never need routine expression. For dogs with repeat impaction, a vet may suggest periodic checks. In that case, let the clinic show you what “too full” feels like and how often your dog tends to refill.

If you use a groomer, ask what they do and what training they have. Some groomers offer expression. Some veterinarians prefer that it be done in clinic, since inflamed sacs can rupture with poor technique. If your dog has a history of infections or abscesses, ask your vet where they want expression done.

Myths That Keep Dogs Itchy

Myth: Licking Is A Natural Fix

Licking can look helpful if a smell release happens. Yet it often leaves the real blockage in place, and it can make skin worse.

Myth: Every Scoot Means Full Glands

Scooting can show up with anal sacs, parasites, skin infection, diarrhea, or itch from other causes. A quick exam prevents weeks of guessing.

Myth: More Frequent Expression Prevents All Problems

Some dogs do better with scheduled checks. Some dogs get more irritation when the sacs are emptied too often. Your vet can set a plan based on what they find, your dog’s stool pattern, and how often signs return.

When To Treat Rear-End Licking As Urgent

Get same-day care if you see swelling next to the anus, a draining wound, blood or pus, or clear pain when your dog sits or tries to pass stool. An abscess can rupture, and infection can spread in surrounding tissue.

If your dog seems tired, won’t eat, or has a feverish feel, don’t wait it out. Those signs add weight to the idea that the problem has moved past simple discomfort.

What You Can Take Away

So, can dogs express their own glands by licking? A little, at times. Yet repeated licking is more often a sign that something needs fixing. If you treat the licking as a message—full sacs, inflamed ducts, soft stool, itch—you’ll get to the real answer faster and spare your dog a lot of discomfort.

If this is your dog’s first episode, a vet visit can sort out the cause and stop the cycle early. If it’s a repeat pattern, ask about stool quality, skin itch, and a longer-term plan based on your dog’s triggers.
