Understanding and Managing Anal Glands in Dogs

What Are Dog Anal Glands?

Anal glands, or anal sacs, are two small pockets located on either side of a dog’s anus. Each gland connects to a small duct that secretes a distinctive, foul-smelling fluid. These glands are typically expressed naturally during a dog's bowel movements, leaving their scent behind to mark territory. Dogs may also involuntarily express their anal glands when they are scared or stressed.

Types of Anal Gland Problems in Dogs

Anal sac disease encompasses several conditions that can affect dogs:

  1. Anal Gland Impaction: This occurs when the fluid within the glands thickens, leading to clogged glands. Impacted glands can cause moderate pain and require significant pressure to express.

  2. Anal Gland Infection or Abscess: Infections can cause severe pain as bacteria lead to pus buildup. Abscesses may form if the infection obstructs the gland opening, resulting in a hot, swollen area around the anus.

  3. Ruptured Anal Gland Abscess: If left untreated, an abscess can rupture, causing severe pain and discharge of greenish-yellow or bloody pus.

  4. Anal Gland Cancer: Anal gland cancer, particularly apocrine anal gland adenocarcinoma, is more common in older dogs and certain breeds.

Signs of Dog Anal Gland Problems

Common signs that indicate your dog may have an anal gland issue include:

  • Scooting

  • Licking or biting the hind end

  • Straining to defecate

  • Discomfort when sitting

  • Anal discharge

Additional signs can include crying, withdrawal, lethargy, reduced appetite, and swelling or redness around the anus. If you observe these symptoms, consult a veterinarian promptly to prevent worsening conditions.

Risk Factors for Anal Gland Issues

Certain breeds and factors increase the risk of anal gland problems:

  • Small breeds like Toy and Miniature Poodles, Chihuahuas, Lhasa Apsos, Cocker Spaniels, Basset Hounds, and Beagles are more prone.

  • Chronic skin conditions, obesity, inadequate dietary fiber, and changes in stool consistency can contribute.

  • Parasites and allergies, whether food-related or environmental, are also risk factors.

  • Genetics play a significant role, especially in smaller breeds.

How To Tell If a Dog’s Anal Glands Are Full

Most dogs express their anal glands naturally. However, if your dog’s stool consistency changes, their glands may become full and require manual expression. This procedure should be performed every three to four weeks if issues persist, either by a veterinarian, a veterinary technician, or a trained groomer.

How to Express a Dog’s Anal Glands

If recommended by your veterinarian, you can express your dog’s anal glands at home. Here’s how:

  1. Preparation:

  • Gather latex gloves, petroleum or water-based lubricant, and paper towels.

  • Have another person hold your dog securely.

  1. Procedure:

  • Place your small dog on a table or kneel behind a large dog.

  • Lubricate your gloved index finger and insert it gently into the rectum.

  • Locate the gland at the 5 or 7 o’clock positions.

  • Place a paper towel over the anus and gently express the gland by applying pressure.

Treatment for Dog Anal Gland Problems

Treatment depends on the specific condition:

  • Manual Expression: Often resolves impactions.

  • Antibiotics and Steroids: Used for infections and abscesses.

  • Surgery: Required in severe cases or for anal gland cancer.

Preventing Anal Gland Issues

  • Diet: Ensure your dog’s diet includes adequate fiber to promote healthy digestion and stool formation.

  • Weight Management: Maintain a healthy weight to reduce the risk of fluid accumulation in the glands.

  • Supplements: Omega-3 fatty acids, fish oil, and probiotics can promote intestinal health and reduce inflammation.
