Let’s Talk About Anal Glands: What They Are & Why They Matter for Your Pet
We know—it’s not the most glamorous topic. But if your dog is scooting across the floor or your cat won’t stop licking their behind, it might be time to talk about anal glands.
This small part of your pet’s anatomy can cause big problems if left unchecked. Here’s what every pet parent should know.
So, What Are Anal Glands?
Anal glands (or anal sacs) are two tiny pockets located just inside your pet’s anus. They’re filled with a smelly, oily substance that’s used for scent marking—basically your pet’s natural “signature” left behind during bowel movements.
Most of the time, these glands take care of themselves. But sometimes they get blocked, inflamed, or infected, which can be painful for your pet.
Signs Something’s Not Right
Anal gland problems are more common than you might think, and they often show up in ways that are easy to spot. Look for:
- Scooting or dragging their butt on the ground
- Constant licking or chewing near the tail or rear
- Swelling, redness, or discomfort around the anus
- A strong, fishy odor
If you’re noticing these signs, your pet might need their anal glands checked.
Does My Pet Need Their Glands Expressed?
Some dogs—and rarely, some cats—need help emptying their glands manually. This can be done quickly and safely by a veterinarian or groomer. Small-breed dogs like Chihuahuas, Poodles, and Cocker Spaniels are more prone to needing this kind of help, sometimes as often as every 4–6 weeks.
If the glands are infected, your vet may recommend additional treatments like antibiotics, anti-inflammatory medication, or warm compresses.
Can I Prevent This?
In many cases, yes! A few simple changes can go a long way:
- Add fiber to their diet. Fiber helps produce firmer stools, which in turn help naturally express the glands. Pumpkin, Metamucil (in vet-recommended doses), or a supplement like Glandex may help.
- Keep your pet fit. Extra weight can make it harder for the glands to empty naturally.
- Stay on top of wellness visits. Regular vet checkups can catch issues early and help rule out underlying causes like allergies or back pain.
What If the Problem Keeps Coming Back?
If your pet experiences chronic anal gland infections or blockages, your vet may eventually recommend surgical removal. This is a last-resort option but can provide lasting relief for pets dealing with ongoing discomfort. Causes of chronic issues can include:
- Genetics
- Food or environmental allergies
- Poor stool quality
- Painful spinal or pelvic conditions
Do Cats Get Anal Gland Problems, Too?
They can—though it’s less common. Overweight or sedentary cats are more likely to develop problems with drainage. If your cat shows similar signs (licking, swelling, odor), it’s worth having their glands evaluated. In persistent cases, dietary changes or even surgery may be considered.
Final Word
Anal gland problems are nothing to be embarrassed about—they’re a common issue we see in both dogs and cats. If your pet seems uncomfortable or is showing signs of a problem, let your vet take a look. A quick appointment can relieve their discomfort and prevent more serious issues from developing.
