High Fiber Dog Food: Solve Anal-Gland Issues (8 Top Options)

What are anal glands and why are they a big issue in dogs?

Anal glands, also known as anal sacs, are glands located a few inches inside the anus, between the sphincter muscles.

If you have seen your dog sniffing another dog at the back, or your dog getting sniffed, it is because of the anal glands.

The anal glands produce a unique scent that dogs use to mark their territory. The scent is produced every time the dog defecates or rubs his behind against a solid surface.

If you have seen your dog sniffing another dog, it is totally normal, and it’s a doggy way of marking its territory.

A healthy dog should produce the scent regularly to empty the glands. However, sometimes the dog may have issues expressing the anal glands naturally, and this could occur due to a health condition or diet problem.

A dog with food bowls

If the glands are not emptied, they will become overfull, and your dog will start rubbing his rear again a wall or carpet.

If they are not expressed soon enough, they can become infected and even rupture.

If your vet examines your dog and finds that he is having anal gland problems, he may recommend switching the current diet to a dog food with a higher fiber content.

This type of diet helps alleviate the problem and eliminates the need to have the anal glands expressed manually every time they are having problems.

​Dog Health Warning Signs

  • Pain when pooping.
  • Pup discharge or blood around the dog’s bottom.
  • A wound around the rectum.
  • Low energy.
  • Licking ​their bottom often.
  • Looking around suddenly and licking the base of the tail.
  • Scooting against a solid surface.

If you notice the above symptoms or suspect that your dog is having anal gland problems, you should contact your vet immediately.

​Using a High Fiber Dog Food to Treat Anal Gland Problems

If your dog’s anal gland problems results from a lack of fiber in the diet, the ideal natural solution to this problem would be to introduce a high fiber diet.

Fiber helps alleviate the problem by making the stool firmer to help in excreting the anal gland’s fluids.

Dogs require a mixture of both soluble and insoluble fiber to assist in regular digestion.

Soluble fibers are those that dissolve in water and can be digested in the dog’s system, whereas insoluble fibers cannot be digested in the dog’s digestive system, but can absorb water to add bulk to the poop.

Factors to Consider When Buying High Fiber Dog Food for Anal Gland Problems

The following are the key factors that you should consider when buying a high fiber dog food:

There are two main types of dietary fiber that dogs require to maintain a healthy gastrointestinal balance. They include:

Soluble Fiber

Soluble fiber is the type of dietary fiber that gets digested in your pup’s system.

It absorbs water, and it adds water to the dog’s stool to make it easy to pass through the digestive tract to the rectum.

It also increases the beneficial bacteria in the digestive tract to assist in digestion.

Insoluble fiber

Insoluble fiber is the type of dietary fiber that is not digested in your pup’s digestive system.

It remains unaltered before and after passing through the digestive tract.

Its role is to add bulk to the dog’s poop to make it firm and heavier to be able to exert pressure on the anal glands to excrete fluids naturally.

If the stool is too soft due to the absence of fiber, your dog may not receive the benefit that the fiber intends to provide.

Fiber Content

Review the guaranteed analysis of the dog food you want to purchase to check the fiber content.

Most premium dry dog foods have fiber content ranging from 3% to 5%, which is an optimal quantity. 

Dogs with anal gland problems may require 6% to 10% crude fiber content. Anything beyond the 10% would be too much for the dog to handle.


While considering the ingredients in the dog food, always go for brands that use real animal proteins as the first ingredient.

Brands such as Pure Balance use meat as the first ingredient, and you can choose from diets that have bison, chicken, beef, venison, etc. as the first ingredient.

From a dietary fiber perspective, check for dog food formulas that include dietary fiber from wholesome ingredients.

Since grains can trigger allergic reactions and cause tummy issues, avoid formulas that include grains such as wheat, corn, and soy.

Preferably, look for diets that use wholesome vegetables as the source of dietary fiber.

Also, check the dog formula to see if it contains prebiotics and probiotics to help in regulating digestion, and assisting in anal gland secretion.

Lastly, check where the ingredients used to prepare the diet are sourced from.

Most pet food manufacturers disclose where their products are manufactured and where ingredients are sourced.

Some trusted countries include North America, Australia, New Zealand, and some parts of Europe.

Some of the best sources of fiber in dog food include:
  • Vegetables such as kales, spinach, and broccoli.
  • Sweet potatoes.
  • Flaxseed.
  • Fruits such as Pumpkin, blueberries, and apples.

Complications from Anal Gland Problems in Dogs

Anal gland problems occur when the glands are not excreted either naturally or manually, thereby filling up and causing discomfort in your dog.

They can also occur when the dog is passing soft stool (after several days of diarrhea), and the pressure is insufficient to empty the anal sacs.

If the glands are not emptied soon enough, the following two problems may occur:

Anal Gland Impaction

Impaction is a common condition in dogs, and it occurs when the glands are not properly expressed.

The gland will thicken and become swollen and distended, thus causing irritation. The fluids within the anal sacs serve as a potential medium for bacterial grown, leading to inflammation.

The bacteria build-up can cause fever and abscesses and requires urgent veterinary treatment. The dog will also experience pain when passing stool.

Anal Gland Abscesses

An anal gland abscess occurs when the impacted anal glands become swollen and infected with bacteria, making the impaction to grow into an abscess.

This stage is the most painful of the anal gland disease, and the dog may scoot across the ground as a way of relieving the irritation in its anus.

It may also bite and lick its behinds as a way of dealing with the discomfort. If not treated early enough, the abscess will rupture, leaving an oozing red hole next to the anus.

If you suspect that your dog is having anal gland problems, get them checked by your vet to prevent it from escalating to this level.

It would be sad to see your favorite furry friend in pain due to a problem that would have otherwise been addressed.

Why Do Dogs Need Their Anal Glands Expressed?

The contents of the anal glands are emptied every time your dog has a bowel movement. If your dog has not pooped for several days, they are at risk of developing anal gland problems.

When the anal glands are not released frequently, they may get blocked and your dog will develop issues.

If your dog is showing signs of anal gland problems, the glands need to be manually expressed. Most professional dog groomers include anal gland expression as one of their services.

You can also have your veterinarian do the anal gland expression.

Remember to talk to your vet about the cause of the problem, and how the problem can be addressed to prevent re-occurrence.

If your dog is healthy and does the anal gland expression on his own, there is no need to manually express them.

Usually, doing manual excretion regularly may weaken the dog’s anal gland muscles and he will lose the ability to self-express his anal glands.

How Anal Gland Expression Works

Most dogs have the ability to empty their anal glands naturally, as long as they are in good health.

The anal glands are spontaneously emptied when the dog is passing firm stool.

Usually, the poop exerts pressure on anal sacs, forcing it to produce the internal fluids. When this happens, there will be a sudden change in his odor.

The gland secretions have a strong unpleasant scent that is also used to lubricate the anal opening, making it is easier to pass stools.

How Dog Owners Can Help Dogs with Anal Gland Problems

If your dog is scooting against the ground and licking the base of their tail, it is certain that something is wrong.

There is a high chance he may be having problems with the anal glands. As a dog parent, there are several courses of action you can take to help alleviate the problem your dog is having.

Switch To A High Fiber Dog Food

If your dog has not pooped or is passing soft stool, it could be because of the diet you are giving him.

Switching to high fiber dog food can help make the stool firm, and increase the number of trips to the bathroom.

A high fiber diet also helps make the stool bulky, in a way that it exerts the required pressure to the walls of the rectum where anal glands are located to enable excretion of the gland’s juices.

Check For Allergenic Ingredients

Are food allergies the main cause of your dogs’ anal gland problems?

If your dogs current diet contains specific elements that your dog is allergic to, they may experience digestive issues that will lead to cases of diarrhea or delayed pooping.

For example, if the allergic reactions cause your dog to have diarrhea, they will pass loose/soft stools that are not enough to exert pressure on the anal glands.

Talk to your vet about possible allergic elements in dog food in order to identify and solve the root cause of the anal gland issues.

Consider Fiber Supplements If The Main Diet Is Lacking Fiber

Check if your dog’s main diet contains enough dietary fiber to help in digestion as well as making the stool firm.

If the main diet is not functional, consider adding fiber supplements to your dog’s feeding routine.

Examples of good fiber supplements include canned pumpkin and psyllium husk powder.

Get Your Dog Examined By A Vet

Best High Fiber Dog Food-Anal Gland Problems

If a change in diet to a high fiber dog food in an attempt to resolve anal gland problems is not enough, you should visit your vet’s clinic to have your dog examined.

Vet visits should be a routine, the same way you visit your personal doctor for a routine check-up.

  • If your vet finds that the anal sac issues still persist, they may recommend a solution depending on the disease stage.
  • If the problem is at the initial stage, they may recommend a specific high-fiber diet that will trigger firm bowel movements to help with anal gland excretion.
  • For advanced stages, your vet may manually express the anal glands to remove the built-up fluids.
  • They may also recommend surgery, where the dog is put under anesthesia, and a surgical operation is performed on the swollen glands to remove the fluids, clean the wound and disinfect it to prevent further infections.
