Anal Gland Problems in Dogs: Signs, Causes and Care

Dogs have two small glands either side of the anus that normally secrete a strong-smelling fluid during defecation, used historically for scent marking; in most dogs these glands empty naturally with normal, well-formed stools and cause no issues at all. In some dogs, particularly smaller breeds, overweight dogs, or those with softer stools, the glands do not empty fully on their own and gradually become overfull, impacted, or occasionally infected.

This is a mechanical and sometimes inflammatory problem rather than a sign of poor hygiene or owner neglect, and it is common enough that many dogs experience it at some point, particularly as they age.

Scooting, licking, odour and discomfort can occur with anal sac disease, but they are not specific to it. Skin disease, parasites, diarrhoea, injury and other problems can resemble it. A veterinarian needs to assess persistent or painful signs rather than assuming full sacs from the behaviour alone.

Many dogs do not need routine expression. A veterinarian can establish whether impaction, inflammation, infection or another problem is present and advise who should perform any necessary treatment. Repeatedly manipulating normal sacs can cause irritation, and painful or swollen areas should not be handled as a routine grooming task.

Recurring episodes need review of the diagnosis and contributing factors rather than an automatic expression timetable. Do not squeeze the area at home, insert tools or assume every recurrent swelling is benign. Ask the clinician to explain the findings and follow-up plan.

Firm, well-formed stools provide natural pressure against the anal glands during defecation that helps them empty on their own, so dogs with chronically soft or loose stools are more prone to recurring gland problems. Adjustments to fibre content in the diet, under veterinary guidance, can sometimes improve stool consistency enough to reduce how often glands need manual intervention.

Maintaining a healthy body weight also matters, since excess fat around the anal area can compress the duct openings and make natural emptying less effective, adding another reason that weight management benefits overall comfort and health beyond the commonly discussed effects on joints and organs.

A swollen, hot, painful area near the anus, a visible abscess, bleeding, or a dog that seems to be in significant pain or is reluctant to sit or pass stool normally needs prompt veterinary attention, since an impacted gland can progress to infection and abscess formation that requires antibiotics or minor surgical drainage. Attempting to express a painful, infected gland at home risks worsening the problem and causing the dog unnecessary pain.

Dogs with frequent recurrent impactions despite dietary adjustment and regular expression may be candidates for a discussion about surgical removal of the glands in persistent, severe cases, though this is generally considered only after more conservative management options have been tried, given it carries its own surgical risks.

Record when scooting or licking started, recent stool changes, previous treatment and how long improvement lasted. Tell the vet about weight changes, itchy skin and any blood or discharge. A photograph from a normal distance can document swelling, but do not lift the tail repeatedly or press the area to demonstrate it. Pain can make a familiar dog bite; keep children away and ask the clinic about safe transport. A new persistent lump, one-sided swelling or recurrent discharge deserves examination rather than assumptions based on a previous episode.

Impaction, infection and an abscess are not all managed identically. The veterinarian may recommend emptying, local treatment, pain relief or other interventions according to the examination. Not every dog with discomfort needs antibiotics, and leftover antibiotics are not an acceptable substitute for assessment. If a swelling opens and drains, the underlying problem still needs care; visible drainage does not mean the issue is finished. Use any prescribed protection and cleaning instructions, and ask what change should trigger an earlier review. Contact the clinic for persistent pain or deterioration instead of repeating a procedure yourself.

An appropriate complete diet and weight plan may help selected dogs, particularly when stool quality or excess weight contributes, but fibre is not a universal solution. Bring the current food and treat list and discuss persistent loose stools or skin problems. Do not repeatedly add supplements that alter intake without establishing the cause. If recurrence continues, ask whether the diagnosis, preventive strategy or referral needs reconsideration. Surgery is an individual discussion for selected problems and has risks, including effects on continence; it is not the inevitable next step after a single episode. Keep the review focused on comfort and documented findings.
