Dog Anal Glands: Scooting, Care & Vet Red Flags

Anal glands and anal sacs: what are they?

Dogs have a pair of anal sacs under the skin on either side of the anal opening. The lining produces a strong-smelling secretion that normally leaves through a small duct as a dog passes stool. The pressure and movement of defecation can help the sacs empty. A nervous or excited dog may also release a small amount suddenly, which can explain a one-off fishy smell.

“Anal gland” is common owner language, but anal sac is the more precise term for the pouch and its contents. The sacs do not need automatic monthly expression in every dog. Some dogs have recurrent disease and need a veterinary plan; others never need a procedure. A professional should decide whether expression is appropriate, because unnecessary or forceful handling can irritate delicate tissue.

The Merck Veterinary Manual overview of anal sac disease and Cornell’s anal sac disease guide describe normal anatomy alongside impaction, inflammation, infection, abscesses, and masses. That range is why a symptom should be investigated rather than labeled at home.

Why might a dog scoot or lick the area?

Scooting is a sign of irritation or discomfort, not a diagnosis. The most familiar possibility is an anal sac that is not emptying well. Contents can become thick or retained, and inflammation or infection can make the area painful. An infected sac can progress to an abscess, which may swell and drain.

Other possibilities include skin allergy or dermatitis, parasites, a change in stool consistency, constipation or diarrhea, irritation after grooming, a foreign material caught in the coat, a perianal fistula, or a growth. The American Kennel Club’s scooting review and VCA’s anal-sac guidance both emphasize that several problems can look alike. A dog can also have more than one contributor, such as itchy skin plus soft stool.

Breed or body size can change the context without naming the cause. Merck notes that small dogs are more often affected by impaction and sacculitis, while larger dogs can still develop anal-sac disease. Body condition, chronic soft stool, constipation, allergies, anatomy, and other health factors may influence recurrence. These are risk associations, not a reason to diagnose a dog from its breed or weight.

What can you observe safely?

Look without spreading, squeezing, inserting a finger, or trying to empty the sacs. Write down what you notice so your veterinarian can see the pattern:

• How often the scooting, licking, or biting happens, and whether it started suddenly.
• Whether the odor is occasional or persistent, and whether there is clear fluid, blood, pus, or fecal contamination.
• Redness, heat, swelling, asymmetry, a firm lump, a skin opening, or a wound beside the anus.
• Straining, repeated attempts to defecate, constipation, diarrhea, mucus, or a change in stool shape or firmness.
• Tail position, reluctance to sit, flinching, whining, hiding, reduced activity, appetite, vomiting, energy, and drinking or urination changes.

A photograph can help document a visible change, but it cannot replace an examination. Do not delay care while trying to compare a photo with internet images. The VCA guide to persistent licking notes that odor, discharge, swelling, or redness alongside licking needs veterinary attention.

When should you call a veterinarian?

Arrange veterinary advice when scooting keeps returning, your dog licks the area persistently, the odor does not settle, or stool changes continue. A single mild episode may pass, but repeated signs deserve an explanation. Puppies can scoot for reasons unrelated to anal sacs, including irritation or parasites, so recurring puppy scooting should not be written off as a habit. VCA’s puppy guidance recommends attention to repeated scooting, fishy odor, swelling, blood, or a wound.

Seek same-day veterinary advice for a painful or rapidly enlarging swelling, marked redness or heat, blood or pus, a draining or open wound, repeated straining, inability to pass stool, sudden severe licking or biting, or pain that makes sitting or walking difficult. Also call promptly if the change comes with fever, unusual lethargy, poor appetite, vomiting, or a marked increase in drinking or urination. Those signs can occur with serious anal-sac disease or another illness and cannot be sorted out remotely.

Use an emergency service if your dog collapses, is profoundly weak, has heavy bleeding, or seems in immediate distress. Keep the dog away from further trauma while arranging transport. Do not attempt to lance, drain, flush, or push material from a swelling on the way to care.

A firm or asymmetric mass also deserves prompt assessment, even if your dog seems fairly comfortable. The American College of Veterinary Surgeons’ anal-sac tumor guidance explains that swelling, straining, constipation, blood, appetite changes, or lethargy can require tests to distinguish a mass from infection or impaction.

What might happen at the veterinary visit?

The veterinarian will ask about onset, stool, diet, allergies, parasites, grooming, previous episodes, and any treatments already tried. They may inspect the skin and perform a gentle rectal examination to assess the sacs and surrounding tissue. A painful dog may need extra handling support or sedation for a safe examination; that decision belongs to the veterinary team.

Depending on the findings, the team may express or flush an impacted sac, examine a sample under a microscope, recommend other tests, or investigate a firm or non-expressible area with imaging or a biopsy. Merck notes that anal-sac treatment can include expression, antimicrobials, anti-inflammatory medication, drainage, or surgery depending on the condition. The goal is to identify what is happening first, not to apply the same procedure to every dog.

For chronic or recurring signs, ask which factors should be reviewed: stool consistency, food tolerance, allergies, parasites, body condition, skin disease, anatomy, and prior expression history. Recurrence may need a longer plan or referral to a veterinary dermatologist or surgeon. The ACVS overview of perianal fistulas is a reminder that painful perianal disease has several possible explanations and may need specialty care.

Safe home care while you arrange advice

If the fur is superficially soiled and your dog is comfortable, you can gently rinse the outside with lukewarm water, use only a cleanser your veterinarian has said is suitable, and pat the area dry. Keep the dog from rubbing the area on rough surfaces. If your veterinarian recommends a cone or another way to limit licking, follow that plan. Stop if cleaning causes pain or your dog resists.

Home care is not the same as emptying an anal sac. Avoid inserting anything into the anus, pressing on a swelling, or attempting an internal or external expression from an online tutorial. Unneeded manipulation can injure tissue, increase inflammation, or make a frightened dog bite. If a veterinary professional has specifically taught you a procedure for your dog, follow that individual instruction and ask when to stop and call back.

Do not use human pain relievers, leftover antibiotics, steroid creams, essential oils, alcohol, hydrogen peroxide, harsh antiseptics, or random “anal gland” products. Do not add pumpkin, psyllium, probiotics, supplements, or a new diet as an emergency response. The U.S. Food and Drug Administration’s animal-drug guidance supports consulting a veterinarian about medicines rather than substituting human products or changing a plan independently.

Can fiber or diet changes help?

Stool quality matters because normal defecation can help the sacs empty, and chronic diarrhea or constipation can accompany anal-sac problems. A veterinarian may recommend a diet or fiber adjustment for a particular dog after considering the full diet, hydration, stool pattern, allergies, medications, and other disease. More fiber is not automatically better, and a home dose cannot be chosen safely from a single scooting episode.

If a vet suggests a change, introduce it exactly as directed and track stool, appetite, water intake, and the original signs. A change in stool is information to report, not proof that the sacs are healthy. A supplement or probiotic may be inappropriate for a dog with an allergy, another gastrointestinal problem, or a medicine interaction. Never use a supplement to postpone an examination when there is pain, swelling, discharge, or systemic illness.

The image below shows food ingredients only; it is not a prescription, a complete diet, or evidence that any ingredient empties anal sacs. Keep food changes individualized and veterinary-led.

Reducing repeat episodes without promising prevention

Once a veterinarian has identified the likely contributor, practical support may include keeping the dog at a healthy body condition, managing an allergy or skin disease, addressing parasites, maintaining a consistent complete diet, and recording stool changes. Regular grooming can keep the outside clean, but grooming does not diagnose anal-sac disease and routine expression is not automatically needed.

Small dogs, overweight dogs, dogs with chronic soft stool, dogs with allergies, and dogs with repeated prior episodes may need a closer follow-up plan. Older dogs with a new firm swelling or changed defecation pattern should be examined rather than placed on a prevention routine. The AKC Veterinary Network discussion of anal-gland disease and Merck’s owner reference on rectal and anal disorders list associated factors while cautioning that they do not identify one cause for every dog.

For your next appointment, bring the symptom log, a list of food and supplements, medication details, parasite-prevention history, grooming timing, photographs of visible changes, and notes about stool. Ask what signs should trigger a same-day call, whether a recheck is needed, and who should perform any future expression. This turns an embarrassing symptom into useful clinical information without promising that any one habit will prevent recurrence.

Dog anal glands FAQ

Is a fishy smell always an anal-gland problem?

No. A dog may release a small amount when frightened or excited. A persistent odor, odor with scooting or licking, or odor with swelling, discharge, pain, or a wound deserves veterinary advice.

How often should my dog’s anal glands be expressed?

There is no safe universal schedule. Some dogs need veterinary expression for confirmed recurrent disease, while others do not need routine expression. Ask your veterinarian rather than starting a monthly routine or asking for an automatic grooming add-on.

Can I express my dog’s anal glands at home?

Do not learn by trial and error. Squeezing a painful, infected, abscessed, or abnormal sac can cause trauma and delay care. Only follow a procedure a veterinary professional has specifically demonstrated and approved for your dog.

Does pumpkin fix scooting?

Pumpkin or another fiber source may be part of a veterinarian-directed diet plan for some dogs, but it does not identify or resolve every cause of scooting. It cannot drain an abscess, evaluate a mass, or replace an examination.

Are anal glands and anal sacs the same thing?

Owners commonly use the terms interchangeably. Anal sacs are the paired pouches beside the anus; glands in their lining produce the secretion. Using either search term is fine, but the distinction helps explain why a problem may involve the sac, its duct, nearby skin, or another condition.

Why is my puppy scooting?

A puppy may scoot because of temporary irritation, stool on the coat, parasites, allergy, or anal-sac discomfort. Repeated scooting, a fishy smell, swelling, blood, or a wound is a reason to call the veterinarian instead of assuming the puppy needs expression.

Can anal-gland disease come back?

Yes, some dogs have recurring episodes. The next plan may involve checking stool, skin, allergies, parasites, body condition, anatomy, or the prior procedure. Recurrence does not prove that one ingredient or product failed, and it does not justify a universal supplement or expression schedule.

What should I do if an abscess bursts?

Blood or pus draining from a painful swelling or opening needs prompt veterinary care. Keep your dog from licking the area, do not pack or disinfect the opening with household products, and ask the clinic for transport and cleaning instructions. A burst area still needs assessment.

Scope note: This guide is general education, not a diagnosis or treatment plan. A veterinarian needs to examine your dog to identify the cause of scooting, pain, swelling, discharge, or a mass.
