Health & Medical

Every household with a dog has witnessed the scoot. Bottom planted on the rug, front legs hauling the whole operation across the living room, usually while guests are eating. It gets laughed about, filmed, sent to the family group chat. And most owners assume it means worms, because that is the folk wisdom handed down for generations.

Worms are rarely the answer. In the overwhelming majority of scooting dogs, the real problem is two small glands sitting just inside the anus at roughly four and eight o'clock, and most of what people believe about them is wrong. Anal glands are not a hygiene job to be emptied on a schedule. They are scent glands, and in a healthy dog they empty themselves naturally every time a firm stool passes through, leaving a few drops of identifying smell that is, to other dogs, an entire social-media profile. The trouble starts when that self-cleaning system jams.

What goes wrong, from mild to messy

First comes impaction, where the normally thin secretion thickens into paste and the glands stay full. The dog feels pressure and starts scooting or licking to relieve it. Left there, the backed-up material irritates the lining and inflames the gland, which is anal sacculitis. The next step is an abscess: bacteria multiply inside the blocked gland, it swells, hurts, and fills with pus. Finally it can rupture through the skin, leaving an open hole beside the anus that drains foul-smelling fluid and takes time to heal. None of these are life-threatening, but the abscess stage is genuinely painful and the rupture is miserable for everyone involved.

Cats get this too, though they show it differently. A dog scoots shamelessly across your carpet; a cat is far more discreet and far more likely to over-groom the area, leaving a bald patch under the tail, or to leave small streaks of blood when defecating. Because it is subtle, cat owners often miss it until an abscess forms.

Why some dogs can't seem to empty them

The single biggest driver is stool consistency. Firm, well-formed stools physically squeeze the glands as they pass, which is the design. Soft or sloppy stools slip through without doing that job, so the glands sit full. That is why chronic soft stools, from any cause, are a major risk factor. Food allergies and intolerances, which are extremely common, are a frequent underlying culprit and worth chasing properly.

Body shape plays a part as well. Overweight dogs carry more fat around the pelvis, which changes the angle and pressure on the glands. Several breeds turn up more often than others, including Cocker Spaniels, Chihuahuas, Toy and Miniature Poodles, Basset Hounds and French Bulldogs, though any dog can be affected. A scarred or deformed exit from a previous abscess is the most reliable way to guarantee repeat trouble, because the normal channel never quite reforms.

Tiny but worth knowing: a firm, painless lump in the same spot that does not respond to routine expression can be an anal sac adenocarcinoma, a cancer that in its early stages looks exactly like ordinary impaction. It also tends to push blood calcium up, which is one reason vets sometimes check calcium in a dog with ongoing gland problems.

What helps, and what does not

For a simple full gland, the fix is expression by someone who knows the anatomy, done gently. A vet nurse can usually do this in minutes. Many owners learn to do it at home, but there is no prize for it, and squeezing healthy glands that do not need it achieves nothing but irritation. This is the myth worth killing: dogs do not need their glands expressed as routine maintenance. Most never need it at all, and the ones who need it monthly probably have an underlying problem that expressing is only masking.

An infected or abscessed gland needs more than a squeeze. The vet empties it under sedation or anaesthetic, flushes it, and often places the dog on antibiotics and pain relief. A formed abscess may need a small incision to drain, or to be lanced and packed, and warm compresses at home help it settle. The bill for a straightforward expression is small; an abscess that needs sedated flushing and antibiotics climbs into the low hundreds, and a full rupture with a draining tract runs higher still.

For dogs who keep coming back, the conversation turns to surgery. Complete removal of both glands is curative for the recurring problem, but it is delicate surgery near the anal sphincter and carries a real, if small, risk of permanent faecal incontinence. That is why it is usually reserved for cases that have become truly recurrent or that involve a tumour, and why a specialist referral is common.

The less invasive work is also the most useful long term. If soft stools are the root cause, firming them up with added fibre such as canned pumpkin or a psyllium product often keeps the glands self-emptying. Weight loss in an overweight dog reduces recurrence. And whenever allergies are suspected, treating the allergy rather than the gland is what finally breaks the cycle.

None of this replaces an actual examination. A dog who scoots once after a bout of diarrhoea is not an emergency, but a dog with a hot, painful swelling, an open draining hole, fever, or one who cannot settle or sit down needs the vet, and so does any lump that does not go away after expression. The good news is that the ordinary version is thoroughly fixable, and most dogs who get the underlying cause sorted stop scooting entirely.
