A dog dragging its bottom across the rug is the sign owners find embarrassing and misread. The usual assumption is worms. The usual cause is the anal glands, two small sacs just inside the anus that normally empty on their own when the dog passes a firm stool.
What goes wrong
When stools are soft, or the dog is overweight, or the skin around the area is inflamed, the sacs do not empty properly. The contents thicken, the area becomes uncomfortable, and the dog does what it can: scooting, licking, chewing at the tail base, sitting down abruptly, or turning suddenly to look at its rear.
Left alone, an impacted sac can become infected and then abscess, which is painful and needs veterinary treatment rather than a home remedy.
The signs to act on today: a visible swelling beside the anus, blood or pus, a foul smell, a dog that cannot settle or yelps when it sits.
Why not to do it yourself
Videos make it look simple. In practice, squeezing sacs that are inflamed hurts, the technique is easy to get wrong, and repeated manual emptying of healthy glands is thought to contribute to the problem rather than solve it by irritating the tissue.
Routine emptying at every groom, for a dog with no symptoms, is not a service worth asking for. If your dog genuinely needs it, that is a veterinary decision based on an examination.
Looking for the cause
A one-off episode is unremarkable. Repeated problems are a signal, and the usual drivers are worth addressing rather than treating the symptom four times a year.
- Stool consistency. Chronically soft stools are the commonest cause. That can be diet, a food intolerance, parasites or a low-fibre ration. Your vet may suggest a fibre adjustment
- Weight. Overweight dogs have more trouble, and weight loss frequently resolves it
- Allergic skin disease. Dogs with itchy skin and recurrent ear problems often have anal gland trouble as part of the same picture
- Breed and conformation. Some small breeds are simply more prone
What a vet actually does
An examination first, because the treatment differs completely between a sac that is simply full, one that is infected, and an abscess that has already formed or burst. Impaction is usually relieved manually; infection needs medication, sometimes instilled directly; an abscess may need lancing and a course of antibiotics, with pain relief in every case.
For a dog with repeated problems, the conversation worth having is the longer one: whether the diet needs adjusting for fibre, whether there is underlying skin allergy, whether weight is a factor, and in a small number of persistent cases, what the surgical options involve and why they are a last resort.
The fibre question
The mechanism that empties the sacs is pressure from a firm stool. That is why vets so often approach recurring cases through the diet rather than through the sacs themselves, and why a dog on a steady, appropriate ration with consistent stools tends to stop having the problem.
Do not start adding bran or supplements on your own: get the amount and the form from your vet, because too much fibre causes its own problems and can interfere with nutrient absorption in a dog that is already on a therapeutic diet.
Other causes of the same behaviour
Scooting can also mean tapeworm segments around the tail, a grass seed, matted fur trapping faeces, a skin infection in the folds, or, in an older dog, a mass. That is why the answer is an examination rather than a guess, particularly if it is new behaviour in an adult dog.
Grooming, and what to ask for
Long-coated breeds need the fur around the area kept short, because trapped faeces cause irritation that looks exactly like a gland problem and frequently leads to one. Ask your groomer for a sanitary trim as part of the routine appointment rather than waiting until there is a mess.
What not to ask for is routine emptying at every visit. If your dog has no symptoms, leave the glands alone; if it has symptoms repeatedly, the answer is a veterinary examination to find out why, not a standing appointment to squeeze them every six weeks.
What you can do
- Keep the stools firm and consistent, with a steady diet and no daily changes of food
- Keep the dog lean, checked by hand monthly
- Keep the fur around the area trimmed on long-coated breeds
- Keep parasite treatment on schedule
- Note the dates when it happens, which is what turns four separate episodes into a pattern a vet can work with
If your dog is scooting during a walk, or a walker notices it, that belongs in the report with the date. It is exactly the kind of small, slightly awkward detail that owners never see because it happens while they are at work.
