Anal glands (anal sacs) are two small glands on either side of your dog's anus that produce a strong-smelling fluid. Normally, they empty naturally during defecation, but some dogs need manual expression. When they don't empty, they can become impacted, infected, or even rupture — requiring expensive surgery.
The average cost of dog anal gland expression is $25, with most owners paying between $10 and $50 per session.

How Often Do Dogs Need Anal Gland Expression?

Signs Your Dog Needs Anal Gland Expression
- Scooting — dragging bottom on the floor or carpet
- Licking/biting — excessively licking the rear area
- Fishy smell — strong odor from the rear
- Swelling — visible swelling near the anus
- Discomfort sitting — difficulty or pain when sitting
- Brown discharge — discharge from the anal area
If left untreated, impacted anal glands can become infected and rupture, requiring anal gland surgery ($500–$1,500).
What Are Anal Glands and Why Do They Need Expressing?
Anal glands (also called anal sacs) are two small glands located on either side of your dog's anus that produce a strong-smelling fluid used for scent marking. In healthy dogs, this fluid is naturally expressed when they pass firm stool. However, some dogs — particularly small breeds, obese dogs, and dogs with chronic soft stool — can't express the glands naturally, leading to impaction, infection, and potentially abscesses that require surgical treatment costing $200–$800.
Signs Your Dog Needs Anal Gland Expression
Watch for these common symptoms:
- Scooting: Dragging their bottom across the floor or carpet
- Excessive licking or biting at the rear area
- A strong, fishy odor coming from your dog's rear
- Redness or swelling near the anus
- Reluctance to sit or visible discomfort when defecating
If you notice any of these signs, schedule an expression promptly. Untreated impactions can rupture, requiring emergency veterinary care at emergency vet visit cost rates.
Who Should Express Anal Glands: Vet, Groomer, or DIY?
Anal gland expression costs $15–$45 at a vet or groomer. Veterinarians perform internal expression (inserting a gloved finger into the rectum), which is more thorough and allows them to check for infection or tumors. Groomerstypically perform external expression (squeezing from outside), which is less thorough but sufficient for routine maintenance. Many owners learn to do external expression at home, but improper technique can cause injury or fail to fully empty the glands. If your dog has recurring issues, a veterinary visit is recommended to rule out underlying causes like allergies or infections.
Preventing Anal Gland Problems
The best prevention is ensuring your dog produces firm, bulky stools that naturally express the glands during defecation. This means feeding a high-fiber diet or adding fiber supplements like pumpkin puree (1–3 tablespoons per meal). Maintaining a healthy weight is also important — overweight dogs have more difficulty naturally expressing their glands. If your dog needs expression more than once a month despite dietary changes, consult your vet about potential underlying issues like food allergies or chronic intestinal inflammation.
