Why Is My Dog Scooting Their Bottom on the Floor? Anal Glands and Other Causes

Scooting is usually a sign of discomfort around the rear end. Medical causes—anal sac disease, parasites, allergies—are most common; see a vet to rule them out.

When to See a Vet

If your dog is scooting, you should contact your veterinarian before assuming it’s just a behavioral quirk. Scooting commonly signals medical problems that need diagnosis and treatment. Seek veterinary attention promptly if scooting is frequent, persistent, or accompanied by any of the red-flag signs listed below.

Quick overview

Scooting = dragging the hind end across the floor. Common medical causes include impacted or infected anal sacs, tapeworms, fleas, allergies, perianal dermatitis, and perianal tumors. Less commonly it can be a learned behavior or attention-seeking. Always rule out medical issues first (Merck Veterinary Manual; AVSAB guidance).

Medical Causes

H2-style: common medical problems that cause scooting

• Anal sac impaction: Dogs have two anal sacs (anal glands) that normally express when a dog defecates. If they don’t drain properly they can become impacted and uncomfortable. Impacted sacs cause itch, licking, rubbing and scooting (Merck Veterinary Manual).

• Anal sac infection/abscess: Impacted sacs can become infected and sometimes abscess. This is painful and may produce swelling, redness, foul-smelling discharge, and systemic signs in severe cases.

• Flea irritation: Heavy flea infestation causes intense perianal itching. Even a few fleas near the tail base can produce scooting.

• Tapeworms (Dipylidium caninum and others): Tapeworm segments around the anus look like rice grains or cucumber seeds and cause intermittent itching that prompts scooting. Tapeworm infection requires deworming with appropriate anthelmintics.

• Allergic dermatitis (atopy, food allergy): Allergies cause generalised or localized itch, including the perianal area, leading to scooting as dogs try to relieve the itch.

• Perianal dermatitis, contact dermatitis: Irritants in the environment or topical products can inflame skin around the anus.

• Perianal masses or tumors: Polyps, cysts, or neoplasia near the anus can cause irritation or obstruction, producing scooting or straining.

• Constipation or diarrhea: Abnormal stool consistency or straining can make expression of anal sacs incomplete, or cause discomfort that prompts scooting.

• Neurologic or orthopedic pain: Sometimes hind-end discomfort from nerve pain or spine problems may be misinterpreted as scooting behavior.

Behavioral Causes (Non-medical)

• Learned behavior or attention-seeking: If scooting brought attention in the past, a dog might repeat it. This is only diagnosed after medical causes are ruled out.

• Grooming habit: Dogs that are fastidious may rub to remove fecal smearing or hair mats.

• Boredom or stress displacement behavior: Infrequent; usually accompanied by other stress signs.

How to Tell the Difference: Medical vs Behavioral

Look for these clues when deciding whether scooting is likely medical or behavioral:

Medical indicators

• Sudden onset or escalation of scooting
• Frequent or continuous scooting
• Visible discharge, blood, swelling, or redness around the anus
• Foul smell from the rear
• Hair loss, scabs or raw skin at the anus
• Presence of tapeworm segments or fleas
• Changes in appetite, energy, or bathroom habits

• Sporadic scooting with no physical signs on exam
• Occurs only in certain contexts (after attention, during play)
• Stops when ignored or when behavior is redirected

What to Observe (Helpful information for your vet)

Gather this information before the appointment to speed diagnosis:

• Onset: When did scooting start? Was it sudden or gradual?
• Frequency and duration: How often and how long?
• Visual signs: Any swelling, redness, blood, pus, or smell?
• Stool appearance: Loose stools, constipation, mucus, blood, or hard pellets?
• Parasite evidence: Small white rice-like pieces near the tail? Any fleas seen?
• Other symptoms: Lethargy, fever, decreased appetite, changes in urination?
• Recent changes: New diet, new home, new grooming products, medications, or travel?
• What makes it better/worse: Does distraction stop it? Does it happen after defecation?
• Reproductive status: Intact or spayed/neutered (some perianal tumors have hormonal links)

Diagnostic steps your vet may take

• Physical and rectal exam, including manual expression of anal sacs
• Fecal flotation to check for intestinal parasites
• Skin cytology or culture if infection suspected
• Anal sac cytology or culture if discharge is present
• Blood work if systemic signs
• Imaging (ultrasound/radiographs) or biopsy if a mass is suspected

Treatment Options

• Anal sac expression: If impaction is present, a trained veterinarian or technician can safely express sacs. Do not attempt this routinely at home unless taught by a professional.

• Antibiotics and anti-inflammatories: For infected sacs or secondary skin infections.

• Drainage and surgery: Abscesses may need lancing; recurrent or problematic anal sacs sometimes require surgical removal (anal sacculectomy) — discuss risks (incontinence) with your vet.

• Parasite control: Praziquantel for tapeworms; flea control for fleas and prevention.

• Allergy management: Diet trials for food allergy, topical therapies, immunotherapy, or medications (antihistamines, corticosteroids, oclacitinib, ciclosporin) as advised by your vet.

• Topical care: Cleaning and medicated shampoos/sprays for perianal dermatitis.

• Behavioral strategies: Only after medical causes are addressed — counter-conditioning, ignoring attention-seeking scooting, and environmental enrichment. Consult a veterinary behaviorist if needed (AVSAB).

Next Steps — Action Plan Based on Severity

• Immediate/urgent: If your dog shows severe pain, swelling, bleeding, fever, or can’t defecate, seek emergency care.

• Prompt but not emergency: Frequent scooting, foul smell, visible discharge, or tapeworm segments — schedule a vet appointment within 24–48 hours.

• Monitor and book routine care: Occasional scooting with no other signs — still book a veterinary check to rule out hidden medical issues. Collect a fresh stool sample to bring.

• Do NOT: Routinely express anal glands at home unless you were trained and told to do so by your vet. Improper technique can cause infection or injury.

Red Flags - Seek Emergency Care

Seek immediate veterinary attention if any of the following occur:

• Sudden, marked swelling near the anus or severe pain
• Drainage of blood or pus from the anal area
• Signs of systemic illness: fever, collapse, severe lethargy, vomiting
• Straining to defecate without passing stool (obstruction)
• Large perianal mass that appeared quickly

Prevention and Home Care Tips

• Keep up-to-date flea control — often prevents tapeworms and flea-related itching.
• Regularly check your dog’s rear for debris, worms, or skin changes.
• Maintain a high-fiber diet or use fiber supplements if recommended by your vet — helps normal stool consistency and anal sac expression in some dogs.
• Avoid over-cleaning or harsh products near the anus — they can cause irritation.

Key Takeaways

• Scooting is a sign, not a diagnosis. Most commonly it points to anal sac problems, parasites, fleas, or allergies.
• Always have a veterinarian evaluate scooting before assuming it’s behavioral (Merck Veterinary Manual; AVSAB).
• Bring a stool sample and notes about onset/frequency to the appointment. Expect a rectal exam and possibly fecal testing.
• Emergency care is needed for swelling, bleeding, fever, or severe pain.

If you’re unsure what to do right now: collect a fresh stool sample, check for fleas or tapeworm segments, keep your dog calm, and call your veterinarian to describe the signs and arrange the most appropriate appointment.
