Quick answer: Pick a complete adult dry food whose maker publishes crude fiber at 4% or higher and names a bulking fiber. Therapeutic high-fiber formulas sit well above that floor. A clinic exam still comes first if the rear is red, swollen, or draining.
This article does not replace veterinary advice. It is a research-desk comparison of published labels. It is not a diagnosis and not a treatment plan.
A complete dry food listing crude fiber at 4% or higher is the diet that can bulk stool enough to empty anal sacs.
This page is a 2026 comparison of published guaranteed analyses from four currently sold complete foods. We did not feed dogs, did not measure stool, and did not run a clinic trial.
Our research team analyzed those four maker pages side by side. The cut we used is the Four-Percent Fiber Floor. It is a label rule, not a clinic protocol.
The Four-Percent Fiber Floor we used
A food entered this article only if it is sold now as a complete adult dog food. Its maker page also had to publish a crude-fiber number of 4% or higher. Its ingredient list had to name at least one bulking fiber.
Bulking fiber, on the pages we read, meant pea fiber, powdered cellulose, or beet pulp. It also meant psyllium husk, wheat bran, pumpkin, or sweet potato.
We left out fiber chews, pumpkin toppers, and treat-only products. We left out puppy-only bags. We left out adult foods whose published crude fiber sits under 4%.
The four that cleared are Royal Canin Gastrointestinal High Fiber dry and Hill’s Prescription Diet w/d Multi-Benefit dry. The set also includes Purina Pro Plan Veterinary Diets EN Gastroenteric Fiber Balance dry.
Nature’s Recipe Grain Free Chicken, Sweet Potato & Pumpkin Recipe dry is the fourth food.
That is the whole set. It is not a ranked list.
Top 7 Dog food for anal gland issues
The picks below are the 7 dog foods for anal gland issues on sale right now, listed with what each suits best and an honest drawback. Any comparison table above comes from maker specifications and may cover different models.
1. Vetnique Glandex for Dogs Anal Gland Chews 60ct Pumpkin + Digestive
Best for: First-time daily chew buyers
Vetnique’s Glandex 60-count pumpkin chews are the named daily option most owner write-ups circle back to. The maker lists a pumpkin-and-digestive formula meant to support firmer stools so glands empty on their own. Owners report they treat it as a weeks-long routine, not a one-day fix.
Pros: Named 60-count chew jar; Pumpkin digestive chew formula Cons: Large dogs empty it fast
2. Native Pet WonderGland
Best for: Picky eaters who skip treats
Native Pet WonderGland is a powder you sprinkle on food, not a chew. Maker pages describe a fiber topper built to firm stool and support natural gland emptying. Owners who skip treats say the mealtime format is easier than another daily bite.
Pros: Sprinkles over regular meals; Premium powder-topper format Cons: Messier than a chew
3. jollifish Anal Gland Spray for Dogs 120ml | Dog Anal Gland Support
Best for: External scoot-itch flare-ups
jollifish’s 120ml spray is a topical, not a food. The listing points to daily rear-end care for itch, scooting, and odor, and the $11.19 bottle is the cheapest item on this list. Owners use sprays like this for surface comfort, not for changing what’s in the bowl.
Pros: Lowest price on list; 120ml topical spray bottle Cons: Adds no dietary fiber
4. Anal Gland Support Chews for Dogs
Best for: Budget chew restockers
This $19.76 chew is the budget daily option on the list. The name promises anal gland support in treat form, and the price sits well below the premium jars. Owners shopping this tier usually want a simple restock, not a flagship formula.
Pros: Lower chew-jar price; Simple daily chew form Cons: Thin published product details
5. Pawfy Anal Gland Chews for Dogs
Best for: Peanut-butter chew seekers
Pawfy’s anal gland chews sit at $34.99, the same premium band as the big named jars. Maker pages list a peanut-butter soft chew aimed at stool quality and everyday gland comfort. Owners who like a treat format report it’s easy to give, so check the count on the listing before you assume a long supply.
Pros: Soft peanut-butter chew format; Premium chew price tier Cons: High cost for the jar
6. puyrzoe Dog Anal Gland Spray for All Pets
Best for: Multi-species households
puyrzoe’s spray is labeled for all pets, not dogs only. Maker copy frames it as a topical for itch, scooting, and odor, and the $16.99 bottle sits above the cheapest spray. Owners with more than one species like having one bottle.
Pros: Labeled for all pets; Portable topical spray bottle Cons: Won’t change stool bulk
7. Veterinary Formula Anal Gland Support Chews for Dogs
Best for: Pharmacy-brand chew shoppers
Veterinary Formula’s chews carry a familiar clinic-aisle name at $29.97. The maker describes a fiber chew meant to support stool quality and everyday gland comfort. Owners who already buy this brand’s other products often stay in the line.
Pros: Familiar vet-brand chew line; Mid-premium everyday price Cons: Still not a complete food

Why bulky stool is the actual job
Dogs have two small anal sacs inside the muscular wall of the rectum. Hill’s Pet Nutrition’s scooting guide says those sacs empty when a dog passes stool.
Soft or small stools do not press hard enough. The sacs stay full. The dog scoots.
The job of the food is stool diameter and firmness. It is not a flavor name on the bag.
Hill’s also notes that scooting can come from parasites, skin irritation, or a simple itch. Redness, swelling, or discharge is a clinic problem. Food will not drain an abscess.
Obesity and chronic soft stool both work against the sacs. A high-fiber bag that still leaves the dog loose has failed the job. Watch the stool, not the marketing line.
How to read a fiber number without fooling yourself
The Association of American Feed Control Officials requires four basic guarantees on a pet food label. Those are minimum crude protein, minimum crude fat, maximum crude fiber, and maximum moisture.
AAFCO says “crude” names the lab method. It does not name the quality of the fiber. The crude-fiber maximum is a legal ceiling, not a serving target.
The U.S. Food and Drug Administration explains the moisture trap. Canned pet food is typically 75 to 78 percent moisture. Dry pet food is typically 10 to 12 percent moisture.
You cannot compare a wet can to a dry bag until you convert both to dry matter.
Royal Canin Academy notes another gap. Crude fiber mostly captures insoluble fiber. It says little about soluble fiber.
Total dietary fiber is the fuller measure. Few retail bags print it.
Royal Canin Academy also publishes typical total-dietary-fiber bands for therapeutic dry foods. Fiber-responsive gastrointestinal diets often sit at 4.5 to 6.0 grams of total dietary fiber per 100 kilocalories. Weight-management diets often sit at 7.5 to 11.0 grams per 100 kilocalories.
Our research team treated those bands as context. We still used the Four-Percent Fiber Floor on the numbers each maker actually prints.
A pumpkin sprinkle is not the same as a complete food. Royal Canin Academy cites one published study in dogs with fiber-responsive large-bowel disease.
Dogs in that study responded to a median daily dose of 30 milliliters of psyllium. That is 2 tablespoons. The range ran from 3.75 to 90 milliliters.
That is a supplement figure. It is not a reason to skip a complete diet.
Attribute comparison of four current foods
This table is attributes only. It is not a ranking. Prices are omitted on purpose.
| Model | Crude fiber as published | Protein / fat as published | Calories as published | Bag sizes the maker lists | Adequacy line |
|---|---|---|---|---|---|
| Royal Canin Gastrointestinal High Fiber dry | Min. 7.9% / max. 13.3% | Min. 21.0% / min. 14.0% | 3,334 kcal/kg; 287 kcal/cup | 8.8 lb and 17.6 lb | Formulated to AAFCO maintenance |
| Hill’s Prescription Diet w/d Multi-Benefit dry | 16% crude fiber, dry matter | 20.7% protein / 13% fat, dry matter | 3,100 kcal/kg; 255 kcal/cup | 17.6 lb and 27.5 lb | Hill’s lists digestive, weight, blood-sugar, and urinary uses |
| Purina Pro Plan Veterinary Diets EN Gastroenteric Fiber Balance dry | Max. 10.0% | Min. 21.0% / min. 10.0% | 3,385 kcal/kg; 324 kcal per 250 ml cup | 6 lb, 16.5 lb, and 25 lb | Formulated to AAFCO adult maintenance |
| Nature’s Recipe Grain Free Chicken, Sweet Potato & Pumpkin Recipe dry | Max. 4.5% | Min. 25.0% / min. 12.0% | 3,470 kcal/kg; 355 kcal/cup | 4 lb, 12 lb, and 24 lb | Formulated to AAFCO adult maintenance |
Three of the four foods are clinic-channel formulas. Nature’s Recipe is the one retail bag that still cleared the fiber floor.
What each formula publishes
Royal Canin lists pea fiber, powdered cellulose, dried plain beet pulp, and powdered psyllium seed husk. That is a mixed-fiber stack. The same page guarantees eicosapentaenoic plus docosahexaenoic acid at a minimum of 0.20%.
Royal Canin also prints vitamin E at a minimum of 294 IU/kg. Ascorbic acid is listed at a minimum of 200 mg/kg. The asterisk on that line says AAFCO does not list ascorbic acid as essential.
The first ingredient on that Royal Canin bag is chicken by-product meal. Read what chicken meal is in dog food if you want that term unpacked. Then read meat meal versus meat.
Hill’s publishes w/d as a multi-benefit dry food. The average-nutrient table on the Hill’s page lists 16% crude fiber after moisture is removed. That is the highest fiber figure in this set.
Hill’s also lists 3,100 kilocalories per kilogram and 255 kilocalories per cup. That is a leaner cup than the other three dry foods. A smaller cup can still be a full calorie day if you follow the bag.
Hill’s names digestive health among the formula’s listed uses. The same page also names weight, blood-sugar, and urinary uses. A clinic should match those extra uses to the dog in front of them.
Purina’s EN Gastroenteric Fiber Balance page lists a unique blend of soluble and insoluble fiber. The ingredient list names dried beet pulp, pea fiber, and wheat bran.
The guaranteed analysis caps crude fiber at 10.0%. It also caps ash at 7.5%.
Purina’s feeding table for that formula lists about 1 1/8 cups a day for a 10-pound dog. A 50-pound dog is listed at 3 1/2 cups. Purina also says smaller breeds can need 15% to 25% more kilocalories per pound than larger breeds.
Nature’s Recipe sits at the floor, not above it. The maker lists crude fiber at a 4.5% maximum. Protein is a 25.0% minimum.
Fat is a 12.0% minimum. Moisture is a 10.0% maximum.
Nature’s Recipe names chicken first and chicken meal second. Sweet potatoes come next. Pumpkin appears later in the list.
The calorie line is 3,470 kilocalories per kilogram. It is also 355 kilocalories per cup.
The Nature’s Recipe feeding chart starts at 1/4 to 1 cup for dogs that weigh 3 to 10 pounds. Dogs at 50 to 100 pounds are listed at 3 to 5 cups. Those are starting points, and the maker says to adjust for body condition.
Our research team counted the fiber claims across the four pages. Three formulas publish a fiber number at 10% or higher, or a 7.9% minimum. One formula publishes a 4.5% ceiling.
How to change foods without losing the bulk
Hill’s prints a 7-day mix on its product pages. Increase the new food while you decrease the old food across that week. A sudden swap can loosen stool, and loose stool undoes the pressure the sacs need.
If the dog starts throwing up undigested food, slow the switch. Keep the last well-tolerated meal in the mix.
Do not stack a new kibble, a new topper, and a new chew in the same week.
Water matters when fiber goes up. Dry food in this set lists moisture maxima from 10.0% to 12.0%. That is normal for kibble, so the bowl still has to be full.
Judge the change by the stool after one to two weeks on the full new ration. You want a formed, bulky stool the dog passes without strain.
Tiny hard pellets are not the goal. Pudding is not the goal either.
Do not treat a fishy smell, swelling, or blood as a food-tuning problem. Those signs need a clinic visit first.
When a diet change is the wrong next step
Food can support emptying. It cannot express a blocked sac. It cannot treat an infected sac or remove a mass.
Hill’s scooting guide says an ignored impaction can infect and abscess. A ruptured abscess is an emergency. Diet talk waits until the area is safe.
Hill’s also lists other drivers. Those include chronic skin disease, low thyroid function, obesity, and, less often, a tumor. A food swap does not answer those questions.
Routine expression at every groom is not a diet plan. Hill’s notes that needless expression can scar the ducts. Ask the groomer what they are doing before you add another bag.
If scooting continues on a high-fiber complete food, the next step is not a fifth brand. The next step is a physical exam.
FAQ
Does canned pumpkin replace a high-fiber dog food?
No. Pumpkin is a single add-in. Nature’s Recipe uses pumpkin as one later ingredient in a complete recipe.
Royal Canin Academy says canned pumpkin is less concentrated than psyllium. It needs more volume for the same fiber. A complete food still has to meet AAFCO’s full nutrient profile.
How much fiber is “enough” for anal glands?
There is no single published dose that fits every dog. Our floor was a maker-printed crude-fiber figure of 4% or higher. The three therapeutic foods in this set sit far above that.
Royal Canin Academy’s fiber-responsive band is 4.5 to 6.0 grams of total dietary fiber per 100 kilocalories. That is a clinic-side range, not a grocery-aisle promise.
Can I use a grain-free bag for this problem?
Only if the bag still clears the fiber floor. Nature’s Recipe Grain Free Chicken, Sweet Potato & Pumpkin Recipe does, at a 4.5% crude-fiber maximum.
Grain-free is not a fiber claim. A grain-inclusive therapeutic food can carry more published fiber than a grain-free retail bag.
How fast should I switch foods?
Hill’s product pages describe a 7-day mix of old food and new food. Stay on that pace unless a clinician gives a different plan. A one-day swap is the usual way to lose stool quality.
Wet food or dry food for anal glands?
Dry food made every row in this comparison because those maker pages published the fiber numbers we needed. The FDA’s moisture ranges still apply if you later compare a can to a bag. Convert both to dry matter before you call one “higher fiber.”
Do I need a prescription formula?
Not always. Nature’s Recipe cleared the floor as a retail adult food. The other three foods are sold as veterinary diets and may require a clinic to release them.
Recurring scooting, pain, or discharge is a reason to go to the clinic before you pick a bag.
What if the new food does not change the scooting?
Give the full ration one to two weeks, then look at the stool. If the stool is still small or soft, the fiber is not doing the job.
If the stool looks bulky and the dog still scoots, the problem may not be diet. Stop shopping and book an exam.
