Anal Gland Problems in Dogs: Signs and Expression: At a Glance
Anal gland problems are common, uncomfortable, and often mistaken for behavioral issues.
Anal Gland Problem Protocol
Anal Gland Issue
| Anal Gland Issue | Signs | Cause | Treatment |
|---|---|---|---|
| Impaction | Scooting, licking, discomfort | Glands not emptying naturally (soft stools, small ducts) | Manual expression by vet, fiber supplement |
| Infection | Swelling, redness, pain, discharge | Bacteria entering impacted gland | Antibiotics, expression, warm compress |
| Abscess | Swollen, hot, painful lump near anus — may rupture | Untreated infection | Drainage, antibiotics, pain management, possible surgery |
| Rupture | Open wound near anus, blood/pus discharge | Abscess that burst | Emergency vet — cleaning, antibiotics, pain meds, e-collar |
Anal Gland Health Checklist
| Watch for scooting, excessive licking, or fishy odor | |
| Feed high-fiber diet — firm stools help glands express naturally | |
| Small breeds (Chihuahua, Toy Poodle, Dachshund) are most prone — check monthly | |
| Have vet or groomer express glands if needed — don't DIY without training | |
| Add fiber: canned pumpkin, psyllium husk, or vet-recommended supplement | |
| Attempt to express glands yourself without training (can cause rupture) | |
| Ignore scooting — impacted glands can become infected/abscessed | |
| Assume scooting = worms (common misdiagnosis — check glands first) |
Firm stools are the natural way anal glands express. A high-fiber diet (canned pumpkin, psyllium husk, fiber-rich dog food) produces bulkier stools that press against the glands during defecation, expressing them naturally. This prevents impaction without manual expression.
If you notice a swollen, hot, red lump near your dog's anus, or an open wound with discharge — this is an anal gland abscess or rupture. It's extremely painful and requires immediate veterinary care. Do not attempt to treat this at home.
Scooting, licking under the tail, and a sudden fishy smell usually mean a dog's anal glands are full and need to be emptied, either on their own during a firm bowel movement or by a vet or groomer. Left impacted, the glands can become painfully infected and rupture. Here's how to tell a normal full gland from one that needs a vet, not just a wipe-down.
Scooting isn't gross, it's your dog telling you something specific
Here's how to read the signs.

Don't squeeze a swollen gland yourself
If the area looks infected, home expression can rupture it or push infection deeper. Let a vet handle anything hot, swollen, or bleeding.
Signs worth watching for
Every dog has two scent glands doing a job you never notice, until they stop working
Anal glands sit just inside the anus at roughly the 4 o'clock and 8 o'clock positions and normally empty a small amount of fluid every time a dog has a firm bowel movement. Most dogs go their whole lives without a human ever needing to touch them.
Problems start when the fluid inside thickens or the gland's duct narrows, so the glands stop draining on their own.
Scooting is a dog's version of asking for help
A dog dragging its bottom across the carpet, licking obsessively at the base of the tail, or suddenly smelling like fish is telling you the glands are full and uncomfortable.
That discomfort escalates fast: a gland that stays impacted for days can become an abscess, a hot, swollen pocket of infection that can rupture through the skin if it isn't treated. Small breeds, overweight dogs, and dogs with soft stool from food sensitivities show this pattern more often.
Expressing the glands is a five-minute fix, but timing and technique matter
A vet or experienced groomer can empty healthy, non-infected glands from the outside in under a minute, and most dogs barely react. Once a gland is abscessed, squeezing it can push infection deeper or rupture the skin, which is why a hot, swollen, or bleeding gland needs a vet, not a home attempt.
Dogs who need manual expression more than 2 to 3 times a year usually have an underlying cause, like low-fiber stool, worth investigating instead of just repeating the fix.
The Merck Veterinary Manual describes anal sac impaction and anal sacculitis as common in dogs, with signs including scooting, licking at the anal area, and a foul odor, and notes that untreated impaction can progress to abscess formation requiring drainage and antibiotics. The same source lists small breed dogs and dogs with chronically soft stool as more frequently affected.
The Merck Veterinary Manual also describes manual expression, performed externally or internally by a veterinarian or trained groomer, as the standard treatment for simple impaction, while noting that an infected or abscessed gland requires veterinary treatment rather than manual expression alone.
