Does My Dog or Cat Need Their Anal Glands Squeezed?


Have you ever seen your dog "scoot" across the carpet or your cat obsessively lick the base of their tail? This common (and often comedic) behavior is a cry for help from their anal glands.


Many pet owners are confused about what these glands are, what they do, and whether they need to intervene with "anal gland expressions." Today, we’ll dive into the specifics of this sensitive anatomical feature and how to tell if your pet needs help.


1. What Are Anal Glands and Where Are They Located?

Anal glands, also called anal sacs, are small, sac-like structures located inside the anus of both dogs and cats. They are situated at approximately the 4 o’clock and 8 o’clock positions within the rectal wall.

These sacs secrete a strong, unique-smelling fluid that acts as your pet's "territorial fingerprint." This scent is why dogs sniff each other when they meet.


2. Do I Need to Regularly "Express" My Pet’s Anal Glands?

The short answer is: Not necessarily.

  • Normal Function: Normally, anal gland secretion is a thin liquid. When your pet defecates, the passage of feces provides pressure; alternatively, muscle contraction during times of excitement or stress automatically empties the sacs.

  • When to Intervene: If the secretion becomes thick and pasty, or if the gland duct is blocked by inflammation (a "blockage"), the fluid cannot escape naturally. In these cases, professional help or regular cleaning is necessary.


3. How Are Anal Glands Professionally Cleaned?

In a clinical setting, there are two primary methods used to empty the anal glands, but they are not created equal:


A. Internal Direct Expression (The Recommended Method)

This is the most thorough method. A veterinarian or technician will insert a gloved finger into the anus to gently press and empty the entire gland.

  • Pros: It ensures the sacs are completely empty and allows the vet to check for blockages, thickening (impaction), or tumors.

  • For Blockages: If a sac is impacted, special tools (cannulas) are used to flush and clear the duct.

B. External Compression (Non-Invasive)

This method involves applying external pressure to the skin outside the anus at the 4 o’clock and 8 o’clock positions, pushing inwards to empty the sacs.

  • Cons: This is only suitable for routine maintenance when the glands are completely healthy.

  • WARNING: If the gland is already inflamed, external pressure will cause severe pain and resistance from your pet. Applying improper pressure can even rupture the sac. Do not attempt this if you have any doubts—always seek professional help.


4. What Are the Symptoms of Anal Gland Blockage or Inflammation?

Anal gland issues are incredibly uncomfortable for pets. Contact your vet if you observe:

  1. Observational Signs: Obsessive licking or chewing around the anus, tail base, or rear flanks.

  2. External Redness/Swelling: The skin around the anus appears inflamed, swollen, or red.

  3. Scooting: Most notably in dogs, dragging the rear end along the floor.

  4. Severe Cases: If the sac ruptures, you may find pus-like or bloody discharge or a large skin defect near the anus.


5. Why Does My Pet Have Recurring Anal Gland Issues?

If your pet is suffering from chronic anal gland discomfort, a veterinarian will assess several potential underlying causes:

  • Physical Impairment: Obesity (which makes it hard to contract muscles effectively), chronic soft stool or diarrhea (not enough pressure to empty sacs), constipation, or narrowing of the gland ducts.

  • Secretion Texture: Abnormal thickness of the secretion or a history of impaction.

  • Over-Secretion: As the anal sacs are skin structures, hormone imbalances or sensitive skin conditions can cause excessive secretion, leading to inflammation.


6. What If the Glands Are Clear, but the Itching Continues?

If your veterinarian confirms the anal glands are empty and healthy, the anal itching may be caused by other conditions:

  • Sensitive Skin/Allergies: This is a very common issue.

  • Skin Infection: Bacterial or fungal infection of the skin around the anus.

  • Intestinal Parasites: Internal worms often cause severe anal itching. Even indoor dogs and cats should have regular deworming to rule this out.


💡 Veterinarian’s Advice

Anal gland discomfort is a highly treatable issue. Early detection of inflammation or abnormal secretions can prevent the pain and risk of a ruptured anal sac. If you are concerned about your pet’s behavior, schedule a preventative check-up today.
