Signs Your Dog's Anal Glands Need Expressing

Anal gland problems are more common than most dog owners realize — and the signs are often misread or ignored. Knowing what to look for means you can act before a minor issue becomes a painful infection.

What Are Anal Glands and Why Do They Get Impacted?

Dogs have two small scent glands on either side of the anus that normally empty during defecation. When the secretion is too thick, the stool too soft, or the gland openings too narrow, the glands don't empty properly and become impacted. Left untreated, impaction leads to infection and abscess.

Top Signs Your Dog's Anal Glands Need Expressing

1. Scooting

The most recognizable sign — your dog drags their rear end along the floor or carpet. This is an attempt to relieve the pressure and discomfort of full or impacted glands. Note: scooting can also indicate worms, so rule both out.

2. Excessive Licking or Biting at the Rear

If your dog is obsessively licking, chewing, or biting at their tail base or rear end, full anal glands are a likely cause. The area feels uncomfortable and they're trying to self-relieve.

3. Strong Fishy Odor

Anal gland secretion has a very distinctive, strong fishy smell. If you notice this odor coming from your dog — especially when they're anxious or excited — the glands may be leaking or overfull.

4. Swelling or Redness Near the Anus

Visible swelling, redness, or a lump near the anus indicates the gland is impacted or infected. This requires veterinary attention — do not attempt to express at home if swelling is present.

5. Straining or Discomfort When Defecating

If your dog seems uncomfortable, strains, or cries when trying to defecate, impacted anal glands may be part of the problem.

6. Sitting Down Suddenly or Reluctance to Sit

Some dogs with full anal glands will suddenly sit down during walks or seem reluctant to sit normally due to discomfort.

Which Dogs Are Most at Risk?

• Small breeds (Chihuahuas, Toy Poodles, Dachshunds) are most commonly affected
• Dogs with soft stools or chronic diarrhea
• Overweight dogs
• Dogs with allergies (which can cause inflammation around the gland openings)

Prevention: Fiber and Supplements

Firmer stools naturally express the anal glands during defecation. Adding fiber to your dog's diet helps significantly. Vetnique Glandex Anal Gland Soft Chew Treats contain pumpkin seed fiber and digestive enzymes specifically formulated to support healthy anal gland emptying and reduce the frequency of impaction.

When to See a Vet Immediately

• Visible swelling, redness, or a lump near the anus
• Blood or pus near the anal area
• Your dog is in obvious pain
• Signs have been present for more than a few days

Final Thoughts

Catching anal gland issues early makes treatment simple. If your dog is scooting, licking their rear, or smells fishy, check their anal glands — or have your vet or groomer check them at the next visit. Prevention through diet is the best long-term solution.
