Dogs Don't Get Hemorrhoids — Here's What's Actually Happening
If your dog is scooting, licking the rear end, or showing what looks like "hemorrhoids," it's almost certainly anal glands. Different problem, different fix, and one of the most preventable recurrent issues in dogs.
Owners search "dog hemorrhoids" thousands of times per month. The condition they're describing is anal gland disease — common, treatable, and fixable.
Why Dogs Don't Get Hemorrhoids
Hemorrhoids are swollen veins in the rectum and anus, caused primarily by upright posture and the venous pressure that comes with it. Humans get them. Dogs, on four legs, do not. The anatomy and pressure dynamics are different enough that classic hemorrhoidal disease is essentially absent in canine medicine.
What owners see and call "hemorrhoids" is usually one of three real conditions: anal gland disease (impaction, infection, or abscess), perianal tumors (more common in older intact male dogs), or rectal prolapse (visible tissue protruding from the anus, an emergency).
This isn't pedantry. The treatments are completely different. Hemorrhoid creams from the human pharmacy don't help any of these conditions. Some can make anal gland abscesses worse. The right next step depends on which of the three is actually happening.
The single most common cause of "hemorrhoid-like" symptoms in dogs is anal gland disease. Roughly 80–90% of owners searching for "dog hemorrhoids" are describing what a vet would diagnose as an anal gland problem.
What Anal Glands Actually Do
Dogs have two small scent-marking glands at roughly 4 o'clock and 8 o'clock positions just inside the anus. They produce a fluid that's normally expressed in tiny amounts each time a dog defecates — the firm stool compresses the glands and pushes a few drops out. This is how dogs leave scent markers and identify each other.
The system works as long as stools are firm enough to compress the glands consistently. When they aren't — soft stool, diarrhea, low-fiber diet, obesity reducing rectal pressure, or anatomical issues — the glands don't empty. The fluid backs up, thickens, and the gland becomes impacted.
From impaction, the progression is predictable. Bacteria multiply in the stagnant fluid → infection. Pressure builds inside the gland → abscess. The abscess eventually ruptures through the skin near the anus, looking exactly like the bleeding lump owners describe as "a hemorrhoid burst."
It's not a hemorrhoid bursting. It's an anal gland abscess perforating, and it needs vet care immediately.
Symptoms Owners Actually See
Scooting — dragging the rear end across carpet or grass. The classic sign. Mild scooting can mean mild irritation; persistent scooting (multiple times a day) means impaction or worse.
Excessive licking of the anal area — usually paired with scooting. Dogs lick when something feels wrong, and the smell of impacted gland fluid is unpleasant enough that they fixate on cleaning.
A foul, fishy odor that doesn't go away after a bath. Anal gland fluid has a distinctive smell. If you wash the dog and the smell returns within hours, the source is the glands, not external dirt.
Visible swelling, redness, or a draining sore near the anus. This is the abscess stage. The bleeding "hemorrhoid" owners describe is almost always an anal gland abscess that's ruptured. Same-day vet visit is required to clean the wound, drain the gland, start antibiotics, and prevent a deeper infection.
What Vets Actually Do
Manual expression ($20–$50, sometimes free with a wellness visit) is the first-line treatment for impaction without infection. The vet or vet tech presses the glands externally or internally (gloved finger inside the rectum) to release the trapped fluid. Many dogs need this every 4–8 weeks if anatomy or diet predisposes them to repeat impaction.
Antibiotics + anti-inflammatories ($50–$150) for infected glands. Typically 7–14 days of oral antibiotics, often combined with topical or injectable medications. Most cases resolve on this protocol if caught before abscess formation.
Abscess drainage ($200–$600) for the bleeding-lump stage. Done under sedation, the abscess is opened, flushed, and packed. Recovery includes antibiotics, e-collar, and follow-up at 2 weeks. This is the stage where waiting an extra day or two can turn outpatient treatment into surgery.
Anal gland removal (anal sacculectomy) ($1,000–$2,500) for chronic recurrent cases. Both glands are surgically removed. Risk of post-op fecal incontinence is real but rare with skilled surgeons. Reserved for dogs that have had 3–4+ infections in a year despite preventive management.
Prevention That Actually Works
Higher fiber diet is the single most evidence-supported preventive intervention. Bulkier stools compress the glands more effectively. Pumpkin (1–2 tablespoons of plain canned pumpkin per day for a medium dog), psyllium husk (Metamucil, vet-dose), or therapeutic high-fiber prescription diets all work.
Weight management. Obese dogs have more fat around the rectum, less effective gland compression, and chronic-impaction risk. Body Condition Score 4–5 out of 9 reduces recurrence noticeably in dogs with a history of anal gland issues.
Routine expression for predisposed dogs. Some dogs (small breeds, dogs with allergies that cause soft stool, dogs with prior infections) benefit from preventive expression every 4–8 weeks at the vet or groomer. This is cheaper than treating recurrent infections and prevents abscesses entirely.
What does NOT work for prevention: human hemorrhoid creams, witch hazel pads, apple cider vinegar, "holistic" anal gland support supplements with no clinical evidence. The interventions that actually work are dietary and weight-based.
