Nobody wants to talk about anal glands. But if your dog scoots across the carpet, leaves a fishy smell on the couch, or keeps licking their rear end, you’re already dealing with the problem whether you want to or not.

Anal gland issues are one of the most common reasons dogs visit the vet. The good news? A daily supplement can often fix the root cause by improving stool quality, so the glands express naturally. We looked at the top options on the market and picked seven worth your money.

7 Best Anal Gland Supplements for Dogs in 2026

1. iHeartDogs 3-in-1 Probiotic for Dogs

This chewable supplement combines probiotics, prebiotics, and digestive enzymes to promote healthy digestion from three angles. The pumpkin and papaya provide natural fiber that firms up stool, which helps the anal glands express on their own during bowel movements. It’s grain-free, gluten-free, soy-free, and allergy-friendly, so dogs with food sensitivities can take it safely. And every bag purchased donates meals to shelter dogs.

2. PetHonesty Scoot Stopper

PetHonesty’s take on anal gland support blends fiber, probiotics, and healthy omegas into chicken-flavored soft chews. The formula targets stool consistency and digestive health while also supporting immune function. No chemicals, wheat, soy, or GMOs. Made in the USA by a NASC (National Animal Supplement Council) member company, so the manufacturing standards are verified. Good option for picky dogs who won’t touch unflavored supplements.

3. Glandex Anal Gland Soft Chew Treats

Glandex is the most recognized name in the anal gland supplement space, and for good reason. The patented formula focuses specifically on bulking and firming stools to reduce the need for manual gland expressions. Most dogs see results in 3-5 weeks of daily use. It comes in a vegan duck and bacon flavor, is vet-recommended, and made in the USA with all-natural ingredients. For a deeper look, read our full Glandex review.

4. NaturVet No Scoot for Dogs

A powder supplement you sprinkle directly onto your dog’s food. NaturVet combines pumpkin, beet pulp, and psyllium husk to encourage normal bowel movements and firm stool. It’s vet-approved, wheat-free, and made in the USA. The powder format works well for dogs who won’t chew supplements or treats. Just mix it in and they won’t even know it’s there.

5. Native Pet WonderGland

Native Pet’s WonderGland takes a vet-developed, clean-ingredient approach. The formula blends natural fiber, pumpkin, and probiotics to support firmer stools and regular gland expression. No fillers, no junk. It comes as a sprinkle-on-food powder that also supports overall gut wellness. Pet parents who’ve tried it report relief from scooting and discomfort within a few weeks of consistent use.

6. Petlab Co. Anal Gland Support

Another powder option targeting scooting and fishy odors. Petlab Co.’s formula centers on probiotics that support healthy bowel function and consistent stool quality. Consistent stool means the glands get the natural pressure they need to empty during defecation. Made with premium ingredients in the USA. Just sprinkle over your dog’s food at mealtime.

7. PawMedica Dog Anal Gland Chews

PawMedica’s chews take a high-fiber approach using pumpkin and beet pulp as star ingredients. They’re soft, treat-like, and made with natural ingredients tested for safety. No fillers. Good for dogs dealing with anal gland issues, constipation, or general digestive concerns. The chews are palatable enough that most dogs take them without fuss.

Why Anal Gland Supplements Work

Your dog has two small glands on either side of their anus. During a normal bowel movement, firm stool presses against these glands and pushes out the oily, smelly fluid inside. That’s how it’s supposed to work.

The problem starts when stool is too soft, too small, or irregular. The glands don’t get enough pressure to empty, fluid builds up, and your dog starts scooting, licking, and generally being miserable. Left alone, backed-up glands can become impacted, infected, or even abscess.

Anal gland supplements address this by adding fiber, probiotics, and digestive enzymes to your dog’s diet. The fiber firms up stool. The probiotics balance gut bacteria for more consistent digestion. The enzymes help food break down properly. Together, they create the stool quality that makes natural gland expression possible again.

They’re not a cure-all. Dogs with infections, abscesses, or structural gland problems need a vet. But for the everyday scooting and the every-6-weeks vet visit for manual expression? A supplement often solves it.

What to Look for in an Anal Gland Supplement

Not all supplements are equal. Here’s what separates the good ones from the filler:

Fiber content: Pumpkin, psyllium husk, and beet pulp are the three most effective fiber sources for firming dog stool. Check that the product lists at least one.
Probiotics: A healthy gut produces consistent stool. Look for named probiotic strains, not just “probiotic blend.”
Digestive enzymes: Help food break down fully so stool is well-formed instead of loose or variable.
Omega fatty acids: Reduce inflammation around irritated glands. Especially important for dogs with recurring issues.
Format your dog will actually eat: Chews, powders, and treats all work. Pick the one your dog won’t reject.

Avoid products loaded with artificial colors, preservatives, or fillers. And if your dog has food allergies, check for common triggers like wheat, soy, and corn.

For dogs with recurring anal gland problems, pairing a supplement with a high-fiber food formulated for anal gland issues gets the best results.

Frequently Asked Questions

What are anal gland supplements for dogs?

They’re dietary products containing fiber, probiotics, and enzymes that support healthy stool formation. Firmer, bulkier stool presses against the anal glands during defecation, helping them empty naturally instead of building up fluid.

How long does it take for an anal gland supplement to work?

Most dogs show improvement within 2-4 weeks of consistent daily use. Some products like Glandex guarantee results in 3-5 weeks. Give it at least a full month before switching to a different option.

Can I use anal gland supplements as a preventive?

Yes. Many owners of breeds prone to anal gland issues (Chihuahuas, Bulldogs, Beagles, Cocker Spaniels) use supplements daily as a preventive measure. Discuss with your vet first, especially if your dog hasn’t had problems yet.

Do these supplements replace vet visits?

No. Supplements support healthy gland function, but they don’t treat infections, abscesses, or impactions that have already developed. If your dog is in pain, swollen, or showing bloody discharge, see your vet right away.

Are there side effects?

Most anal gland supplements are very safe. Some dogs experience temporary digestive upset (gas or loose stool) during the first few days as their gut adjusts to the added fiber. This usually resolves on its own.

Can I give my dog human fiber supplements instead?

No. Human fiber supplements may contain ingredients that aren’t safe for dogs (like xylitol) or are dosed for human-sized bodies. Always use a product formulated specifically for dogs.

How often should I give my dog an anal gland supplement?

Most are designed for daily use. Follow the dosing instructions on the package, which are usually based on your dog’s weight. Check with your vet if you’re unsure about the right amount.

Healthy Glands, Happy Dog

Anal gland problems are uncomfortable for your dog and unpleasant for everyone in the house. The good news is that a daily supplement often fixes the issue by targeting the root cause: stool quality.

Pick one that matches your dog’s preferences (chew vs. powder), give it 3-4 weeks of consistent use, and keep an eye on the scooting. For most dogs, that’s all it takes. Pair the supplement with a balanced, fiber-rich diet and regular exercise for the best long-term results.

And if the scooting doesn’t stop or you notice swelling, discharge, or pain, don’t wait on it. Get your dog to the vet. Supplements are great for prevention and maintenance, but they’re not a substitute for professional care when things get serious.
