Labrador Anal Gland Problems: Signs and What to Do Next

Last updated: October 2026

Labrador anal gland problems usually announce themselves with one move: your dog sits down and drags their bottom across the floor. Add a fishy smell, nonstop licking under the tail, or a dog who suddenly hesitates to sit, and full, blocked or infected anal glands go near the top of the list. Most cases are quick for a vet to sort out. The ones that get ugly are the ones left for a week to “see if it passes.”

The first time you see a Lab scooting across the kitchen tiles, it can be bewildering: soft poop one day, scooting the next, and a smell that clears the room. Plenty of owners don’t know anal glands are even a thing until that moment, and this guide is everything I wish I’d had in front of me.

What Labrador anal glands actually are (the 30-second version)

Anal glands, also called anal sacs, are two small scent glands just inside a dog’s anus. In many dogs, they empty naturally during bowel movements. When they don’t, the material inside can thicken, build up, and turn into irritation, infection, or even an abscess.

They sit roughly at the four o’clock and eight o’clock positions, and the fluid inside is a strong-smelling scent signature. It’s the reason dogs greet each other the way they do. In a healthy Lab, the sacs empty a little every time a firm poop presses past them, and nobody has to do anything.

That chain (full, then impacted, then infected, then abscessed) is the whole story of this condition. Almost everything below is about spotting where your dog is on it, and stopping it early.

Common signs of Labrador anal gland problems

Once the glands stop emptying properly, a Lab tends to act like something is “wrong back there,” because something is.

The classic sign is scooting across the floor or grass. A dog may also turn and lick the rear end over and over, seem restless, or suddenly sit down with a bit of caution. Some dogs strain to poop. Others yelp, smell unusually fishy, or leave a small smear where they’ve been sitting.

Not every rear-end problem is caused by anal glands. Worms, diarrhea, skin irritation, and allergies can look similar. That’s why pattern matters more than one odd moment. This is also more common than most owners assume: the American Kennel Club’s guide to anal gland disease notes that a poor diet or inherited anatomy can make the sac malfunction in any dog, and problems like this affect a meaningful share of dogs at some point in their life.

Here’s a quick way to read what you’re seeing:

If the behavior repeats, don’t wait for it to “work itself out.” Anal gland trouble can go from annoying to painful in a day or two.

The PDSA guide to blocked anal glands in dogs gives a solid overview of the symptoms vets want owners to notice early.

Signs that are easy to miss

Scooting gets all the attention, but it isn’t always the first clue. With some Labs, the earliest sign is much quieter: they start sitting slightly to one side on their bed, like they’re perched on a pebble. A few other subtle ones worth knowing:

• Chasing or staring at the tail in a dog who has never cared about it before.
• Licking the back legs or flank rather than directly under the tail.
• A small damp or brown mark on bedding, the sofa, or your lap after a cuddle.
• Reluctance to have the tail touched during drying or brushing.
• Grumpiness about jumping into the car, which compresses that area.

Why Labs can end up with blocked or irritated glands

The Labrador Retriever is sturdy, cheerful, and often pretty stoic. That means some Labs won’t make a big fuss until the discomfort is obvious. The scooting often shows up before it’s clear how sore they are.

Several things can set the stage for anal gland trouble. Soft stool is a big one. If bowel movements are loose or inconsistent, the glands may not empty well. That matters for Labs, because many are famously food-motivated and prone to stomach upsets if they eat too much, eat too fast, or scavenge things they shouldn’t.

Weight can play a part too. Labradors are known for their enthusiasm around food, and extra weight can make a lot of health issues harder to manage. Fat around the base of the tail changes how firmly the sacs get squeezed. If a Lab is overweight, less active, or dealing with chronic loose stool, repeat gland problems become more likely.

Skin disease and allergies can also stir the pot. A dog with itchy skin often licks and chews more, including around the rear, and the same inflammation that makes paws itch can inflame the sac openings. That irritation can happen alongside anal gland disease, which is why the full picture matters. PetMD’s overview of dog anal glands is helpful if you want a plain-language look at how these pieces fit together.

Age matters a little, but not in a neat, tidy way. Adults tend to show this problem more often, though puppies can still get rear-end irritation. With puppies, it’s not worth guessing. Worms, diarrhea, and skin irritation are all on the list too.

Risk factors at a glance

What to do next when your Lab starts scooting

The first step is simple. Slow down and look at the whole dog, not just the symptom.

If your Lab scoots once after a soft poop and then goes back to normal, it’s fine to just watch closely for a day. If the scooting repeats, the licking ramps up, or your dog seems sore, it’s time to book a vet appointment.

A calm plan usually looks like this:

1. Watch the behavior for a short window, not for a week. Repeated scooting, licking, odor, or discomfort means it needs attention.
2. Check the area from a distance if your dog allows it. Look for redness, swelling, discharge, or a wound near the anus.
3. Note the poop. Was it firm, soft, bloody, or hard to pass?
4. Take a quick photo of anything that looks swollen or red. Vets find it useful if things look different by the time you’re in the exam room.
5. Call your vet if signs continue or if your dog seems painful.

I don’t recommend squeezing anal glands at home unless your vet has shown you how and told you it’s appropriate for your dog. It’s easy to make a sore area more painful. It’s also easy to miss an infection, abscess, or another issue that needs treatment instead of pressure. I asked my vet to show me once, watched her do it, and still decided it was a job I’d rather leave to someone who does it every day.

A fishy smell is one of those clues owners remember. If you catch it once, take note. If you keep smelling it, or your dog keeps turning to lick, move the issue up your list.

Pain changes the timeline. If your Lab cries out, refuses to sit, has swelling beside the anus, bleeds, or seems unwell, don’t wait for the next available routine visit. Those signs can mean the gland is infected or close to bursting.

Do Labs need their anal glands expressed regularly?

Short answer: most don’t. A healthy Lab with firm, regular poops empties their own glands, and plenty of Labs go their whole lives without anyone touching them.

Routine expression “just because” is where I’d push back. Squeezing sacs that don’t need it can irritate the ducts, and some vets believe it can make the glands lazier about emptying on their own. The dogs who genuinely benefit from a schedule are the ones with a track record: repeated impactions, sacs that always fill with thick material, or anatomy that makes natural emptying hard. For those dogs, your vet will usually suggest an interval and adjust it based on what they find each time.

If a groomer is already doing it at every visit and your Lab has never had a problem, it’s worth asking your vet whether that’s needed at all.

How vets treat anal gland issues, and when it’s urgent

Most uncomplicated cases are treated by emptying the glands and checking for infection or swelling. If the material is thick, pasty, or hard to express, your vet may need to flush the area or prescribe medication. If there’s infection, antibiotics and pain relief may be part of the plan.

When an abscess forms, the area may look red, hot, swollen, or even open and draining. That is not a “keep an eye on it” situation. It’s painful, and it needs veterinary care.

The VCA explanation of anal sac disease in dogs lays out the usual treatment path, including what happens when infection is involved.

Some dogs need repeat care. Others have one episode and never deal with it again. That’s why it’s best not to jump straight to a long-term routine after a single flare-up. Repeated manual expression without a good reason can irritate the area in some dogs, so it’s best to follow your vet’s plan instead of building your own.

Surgery exists for severe, repeat cases, but it’s not the starting point. Most Labs improve with the right diagnosis, treatment, and a look at whatever is driving the problem underneath.

Preventing repeat anal gland trouble in Labradors

Prevention starts with stool quality. In plain terms, the goal is regular, firm bowel movements. That often means looking hard at diet, treats, scavenging habits, and any pattern of loose stool.

For some dogs, the answer is as simple as cutting out the extras that upset the stomach. For others, a vet may suggest diet changes, added fiber, or an allergy workup. Fresh water, daily activity, and healthy body weight all help too. If your vet suggests a fiber boost, plain canned pumpkin (not pie filling) or a vet-recommended fiber supplement are the usual starting points, but get a dose from them first so you don’t swing things too far the other way.

This is one place where breed-specific care matters. Labs are active, enthusiastic, and often convinced every snack is theirs by birthright. Keeping weight in check and digestion steady helps more than one body system. My common health issues in Labradors guide can help if you’re seeing stool changes, skin trouble, or weight gain alongside gland flare-ups. If the scales are part of the picture, my plan for helping an overweight Labrador lose weight safely walks through it step by step, and if itchy skin keeps showing up at the same time, my guide to choosing food for a Labrador with itchy skin is the next thing I’d read.

If your dog has repeat episodes, keep a simple record. Write down what the poop looked like, what food changed, whether itching was worse, and when the scooting started. That tiny bit of detective work can save time at the vet. When I did this for a couple of months, the pattern was embarrassingly obvious: every flare-up followed a week of extra chews and treats from visiting relatives.

My Take

The stool quality connection genuinely surprised me when I first came across it — I’d assumed anal gland problems were mostly a grooming issue. But once I understood that firmer, consistent stools are what empty the glands naturally during a bowel movement, diet management started making more sense as the first line of defence. For Labs specifically, that often means being stricter about extras — fewer soft treats, fewer table scraps, and a close look at whether the main food is causing any looseness. If a Lab is scooting regularly, your vet has ruled out infection, and nothing else seems to be the cause, a 2-week trial of cutting extras and keeping the diet consistent is worth talking through with them before escalating further. That said, an abscess or infection always goes straight to the vet — there’s no home fix for those.

What matters most

Anal gland problems in Labs are unpleasant, but they’re usually manageable once the signs are spotted early. Scooting, rear licking, a fishy odor, and pain during bowel movements all deserve attention, especially when they show up together.

The biggest takeaway is this: don’t ignore repeat symptoms. A mild blockage can turn into an infection fast, and a quick vet visit is usually much easier than dealing with an abscess later.

FAQ

How do I know if my Labrador’s anal glands are full?

The usual signs are scooting, repeated licking under the tail, a fishy smell, and discomfort when sitting or pooping. Full glands can also leak a small amount of brownish fluid.

Should I express my Lab’s anal glands at home?

Not unless your vet has shown you how and said it’s right for your dog. Home expression can hurt a sore dog and can miss infections, abscesses, or other problems.

Can food cause anal gland problems in Labradors?

Food doesn’t directly “cause” every case, but it can play a big part. If a diet leads to soft stool, stomach upset, weight gain, or allergy flare-ups, anal gland trouble is more likely.

Are anal gland issues an emergency?

Sometimes. If your Lab has swelling, bleeding, severe pain, trouble pooping, or seems unwell, call your vet promptly. Those signs can mean infection or an abscess.

Do some Labs keep getting anal gland problems?

Yes, some do. Repeat cases often point to an underlying issue such as soft stool, excess weight, allergies, or anatomy that makes natural emptying harder.

Can a groomer express my Labrador’s anal glands?

Many groomers offer this as a routine add-on, and it can help dogs who need regular emptying. It’s worth asking your vet first if your Lab has never had the glands expressed before, since a vet visit can also confirm there’s no infection or other problem hiding behind the same symptoms.

My Lab suddenly smells fishy but isn’t scooting. Is that the glands?

Quite possibly. Dogs sometimes empty their sacs all at once when they’re startled or stressed, which is why the smell can appear out of nowhere at the vet or after a fright. One whiff that fades within a day isn’t a worry. A smell that keeps coming back, especially with licking, is.

Is scooting always anal glands?

No. Worms (tapeworm segments look like grains of rice near the tail), diarrhea leaving the area sore, allergy itch, and matted fur can all cause it. That’s part of why a vet check beats guessing.

Can an anal gland abscess heal by itself?

Sometimes one bursts and drains on its own, which can look like it’s “sorted itself out.” It still needs a vet. The wound has to be cleaned properly, infection is usually present, and a sac that has abscessed once is more likely to do it again without a plan.
