Is your dog scooting, licking, or getting monthly gland expressions?
Recurring anal gland problems are almost always a diet signal. Firm stool does the expressing; runny stool does not — and food allergies are a common reason for runny stool.
Recurring anal gland issues is one of the most under-written topics in pet health content. Owners are told the glands need 'expressing' every 4-8 weeks like it is a fact of dog life; vets do the expression in a few minutes; the owner goes home £30-50 lighter and the cycle restarts. It is rarely questioned. But ~80% of healthy dogs never need gland expression in their lifetime. If yours needs it regularly, something is wrong — and that something is almost always fixable through diet.
The anatomy: the anal glands sit at roughly 4 and 8 o'clock around the anus and release a small amount of scent fluid when a firm stool passes and puts pressure on them as it goes. Firm stool = natural expression. Soft or runny stool does not apply enough pressure, so the fluid builds up, thickens, and becomes uncomfortable (scooting) or impacted (redness, swelling, sometimes rupture). Recurring gland problems are therefore a stool-quality problem. And stool quality is a diet problem.
Food allergies drive this cycle more often than owners realise. A low-grade allergy that is not causing visible itch can still be inflaming the gut lining enough to soften stools, break the natural expression cycle, and back the glands up. The fix is not a four-weekly trip to the vet — the fix is firming the stool, which usually means adding soluble fibre and, if that is not enough, running an elimination diet.
Check the current food while you start the fibre trial
Fibre supplementation and elimination diets work better in parallel than in sequence. Scan the current food for common allergens now — if any are present, switching after the 4-week fibre trial fails becomes straightforward.

Frequently asked questions
How often is "too often" for a dog to need anal gland expression?
Any frequency that is not zero is a signal something is off. Healthy dogs express their own glands every bowel movement and never need manual help. If your vet or groomer is expressing the glands at every visit, it has become a management routine rather than a solution — and management is more expensive over a dog's lifetime than fixing the underlying stool consistency. Once a dog has needed two manual expressions in 12 months, it is worth investigating rather than scheduling the next one.
What is the fastest thing I can try to stop my dog scooting?
Add soluble fibre to the food. The simplest and cheapest option is psyllium husk powder (unflavoured, sugar-free, from any health food shop or pharmacy): 1 teaspoon per 25 lbs of body weight per day, split across meals, stirred into the food with a tablespoon of water per teaspoon. Plain pumpkin purée works too but takes more of it. Most owners see visibly firmer stools within 3-5 days, and scooting usually stops within 2 weeks. If it does not, psyllium was not the answer.
Can food allergies really cause anal gland problems without any itching?
Yes — and this is the missed diagnosis in most chronic-scooting cases. Food reactions exist on a spectrum. A full allergy produces the classic itch / ear infection / paw licking pattern; a mild intolerance can inflame the gut lining enough to soften stools without producing any visible skin signs at all. If you have tried fibre for 3-4 weeks with no improvement, or if the stool is also sometimes loose or contains mucus, running an 8-12 week elimination diet with a novel protein is the correct next step.
My vet wants to remove the anal glands. Is that a good idea?
Anal gland removal (anal sacculectomy) is a reasonable option for truly refractory cases with confirmed chronic impaction or abscessation that has not responded to fibre, elimination diets, and probiotics — but it is a last resort, not a routine solution. The surgery carries a 2-10% risk of faecal incontinence and some dogs never fully regain normal continence. Exhaust dietary options first. If the glands have been removed on one dog and the problem recurs in another, the shared factor is almost always the diet both dogs were on.
Which breeds are most prone to anal gland issues?
Small breeds are over-represented because of anatomy (narrower anal canal, less stool mass to apply pressure): Chihuahuas, Toy Poodles, Maltese, Shih Tzus, Yorkies, Dachshunds, Cavaliers. Cocker Spaniels are also classic. Overweight dogs of any breed get it more often because body-fat distribution can compress the glands. If your dog is in one of these categories, assume stool consistency is the lever and be aggressive about fibre and food quality rather than accepting monthly expressions as "just how small dogs are".
What is the best long-term diet to prevent anal gland issues?
A food that consistently produces firm, well-formed stools — which means adequate insoluble fibre (4-6% of dry matter is typical for a mid-fibre formula), quality protein sources, and no ingredient the dog is reacting to. Many owners have good luck with "sensitive digestion" or limited-ingredient formulas once they have identified their dog is reactive to specific proteins. Added beet pulp, pumpkin, psyllium, or chicory root in the ingredient list is usually a positive sign for fibre content. Avoid high-fat foods in prone dogs — fat softens stool even in the absence of allergy.
