Why Is My Dog Scooting? Anal Glands and the Fiber Fix
By Caroline Buck, Co-founder of Petaluma
With veterinary nutrition insights from Dr. Sarah Dodd, BVSc, PhD, DECVCN
That drag-the-rear-across-the-carpet move is equal parts funny and worrying. Scooting is one of the most common signs that a dog's anal glands are not emptying the way they should. The good news is that the most effective long-term fix is also one of the simplest: firmer, bulkier stool, which usually comes down to dietary fiber. This guide explains what the anal glands are, why fiber helps them empty on their own, which foods deliver it, and the signs that mean it is time to call your veterinarian.
Scooting usually means the anal glands, two small scent sacs just inside the anus, are full or irritated. The most effective long-term fix is firmer, bulkier stool, and the simplest way to get there is more dietary fiber. A fiber-rich food like Petaluma's Whole Food Mixer supports that, alongside a vet check to rule out infection.

What are anal glands, and why do dogs scoot?
The anal glands, also called anal sacs, are two small pouches sitting just inside your dog's anus at roughly the four and eight o'clock positions. They are lined with apocrine glands (sweat glands alongside hair follicles) that produce a strong-smelling fluid. Normally, a firm stool presses against these sacs as it passes and squeezes a little of that fluid out, which is why dogs sniff each other the way they do. It is a scent-marking system.
The trouble starts when stool is too soft to apply that pressure. The fluid thickens, the sacs stay full, and the pressure becomes uncomfortable. Your dog scoots, licks the area, or chases their tail to relieve it. Left unaddressed, full sacs can become impacted (blocked), then infected, and in severe cases they can abscess and rupture. Common signs to watch for include:
- Scooting: dragging the rear along the floor or grass.
- Excessive licking or biting at the rear or base of the tail.
- A sudden fishy or foul odor that follows your dog around.
- Swelling, redness, or discomfort when sitting.
Chronically soft stool is one of the most common reasons these glands stop emptying on their own, which is exactly where diet comes in.
How fiber fixes the problem
A high-fiber diet is the standard long-term recommendation for dogs with repeated anal gland problems, because it adds bulk and firms the stool. Fiber does this by binding water in the large intestine, which increases fecal weight and gives the stool the structure it needs to press on the sacs and empty them naturally as your dog passes it.
The two types of fiber play different roles, and a good diet uses both. Insoluble fiber (found in whole grains and vegetables) adds bulk and speeds transit. Soluble fiber (found in ingredients like oats, pumpkin, and flax) holds water and gives stool its formed, cohesive quality. The evidence that fiber improves stool consistency in dogs is solid: a 2022 multicenter veterinary study found that a fiber-supplemented diet rapidly improved stool consistency in dogs with chronic large-bowel issues, and a separate study of 30 dogs saw large-bowel diarrhea resolve on a combination of a high-fiber diet and probiotics (2022 multicenter study; 30-dog study).
Plant-based diets have a natural advantage here, because they are built largely from fiber-rich whole foods. As Petaluma's formulator Dr. Sarah Dodd, BVSc, PhD, DECVCN, notes, our food is a "fiber-rich diet." You can read more on the topic in our guides to fiber and gut health and fiber and probiotics for dogs.
The best high-fiber foods and add-ins
You have two levers: the base diet and a few simple toppers. Start with the base, since it does the most work.
| Fiber source | How to use it |
|---|---|
| A fiber-rich complete food | The biggest lever. Petaluma's plant-based recipes are built on high-fiber whole foods like chickpeas, oats, barley, and flax. |
| Plain canned pumpkin | 1 to 2 tablespoons with each meal, scaled down for very small dogs. Use plain canned pumpkin, never pumpkin pie filling. |
| The Whole Food Mixer | A complete-and-balanced, fiber-rich topper you can add to any bowl without unbalancing the diet. |
| Whole-food snacks | Swap low-value treats for fiber-forward options like sweet potato. |
Petaluma's Adult Baked Recipe and the Whole Food Mixer are both fiber-rich by design, and a few crumbles of Sweet Potato Jerky make an easy fiber-forward swap for old treats. Add fiber gradually over a week or so. A sudden jump can cause gas or loose stool, which is the opposite of what you want. And keep fresh water available, since fiber works by holding water.
When to see your veterinarian
Fiber is a prevention and maintenance strategy, not an emergency treatment. See your veterinarian if your dog is scooting persistently, if you notice swelling, bleeding, pus, or a strong odor, or if your dog seems to be in pain. Impacted or infected glands often need to be expressed and sometimes treated with medication, and that is a job for a professional rather than something to manage at home.
It is also worth remembering that scooting can have other causes, including intestinal parasites, food allergies, or skin irritation near the tail. If more fiber does not resolve the problem within a few weeks, a veterinary visit will pin down what is really going on.

Why is my dog scooting on the carpet?
Scooting is most often caused by full or irritated anal glands. When stool is too soft to press on the sacs and empty them, fluid builds up and becomes uncomfortable, so your dog drags their rear to relieve it. Firmer, higher-fiber stool usually helps, and persistent scooting warrants a vet visit.
Does fiber really help dog anal glands?
Yes. A high-fiber diet is the standard long-term recommendation for recurrent anal gland problems. Fiber binds water in the large intestine to bulk and firm the stool, and that firmer stool presses on the anal sacs so they empty naturally during a bowel movement.
How much pumpkin should I give my dog for anal glands?
A common guideline is 1 to 2 tablespoons of plain canned pumpkin with each meal, scaled down for very small dogs. Use plain canned pumpkin, not pumpkin pie filling, which contains spices that are not good for dogs. Add it gradually to avoid loose stool.
Can a dog have too much fiber?
AAFCO does not set a minimum requirement or a safety upper limit for fiber, so excess fiber is not considered dangerous. The main issue with too much, too fast is temporary indigestion such as gas or loose stool. Increase fiber gradually and keep fresh water available.
Should I express my dog's anal glands myself?
In most cases, no. Routine at-home expression can irritate the sacs and is best left to a veterinarian or trained groomer, especially if the glands are impacted or infected. The goal of a fiber-rich diet is to help the glands empty on their own so manual expression is rarely needed.
When should I take my dog to the vet for scooting?
See your veterinarian if scooting is persistent, or if you notice swelling, bleeding, pus, a strong odor, or signs of pain. These can indicate an impaction, infection, or abscess that needs treatment. Also see a vet if more fiber does not help within a few weeks, since other causes like parasites or allergies are possible.
