Sep 04, 2025

Author:Amanda Lyu

If you are a dog owner, you may have heard about dog anal gland problems. These small glands are on each side of your dog’s anus. They release a scent when your dog poops.

Sometimes, these can become full, blocked, or infected. Knowing how to tell if dogs anal glands are full becomes important because ignoring the problem only makes it worse for your dog. They may develop swellings and infections.

This guide will explain the signs, causes, and ways to help. You will also learn how to prevent future dog anal gland issues and keep your pet comfortable.

Why Do Dogs Have Anal Glands?

Dogs use their anal glands for scent marking. It is part of how they communicate with other dogs. When they pass stool, the pressure helps empty the glands.

But do dogs need anal glands? The answer is yes. Their use is different from that of wild animals, but that doesn’t mean they don’t have to use them.

Problems start when the glands do not empty properly. Small breeds often have more issues because their glands are narrow, and fluid can get stuck.

How Do You Know If Your Dog Needs Glands Expressed?

One of the most common signs is scooting. If your dog drags its bottom on the floor, this may mean the glands are full. Licking the area is another sign.

You may also see swelling near the anus or notice a bad smell. If you have ever wondered how do you know if your dog needs glands expressed, look for these early warning signs.

Changes in stool can also happen. Very dark or tarry stool can be a sign of other health problems. If this happens, read this guide on dog black stool to understand possible causes.

Symptoms of Blocked Anal Glands in Dogs

Blocked glands can cause discomfort and pain for your dog. Here are some of the most common symptoms of blocked anal glands in dogs so you can have them treated immediately:

● Dragging their bottoms on the floor

● Licking or biting near the anus

● Swelling or redness around the anus

● The rear gives off a foul smell

● Discomfort when passing stool

Take immediate action if you notice any of these signs. Contact your vet immediately.

Knowing how to check dogs anal glands can ensure your dog’s health and make sure they are not in pain.

Causes of Anal Gland Problems

Prevention is the best cure to all anal gland problems. Being familiar with the causes will enable you to ensure that your dog is not subject to the risk of any of these problems.

Diet Problems

Diet is one of the main reasons dogs develop gland issues. The stool becomes too soft when there is less fiber. This causes the glands not to press enough on themselves to empty them. With time, this leads to the glands being full or blocked.

If you’re wondering can food cause anal gland issues in dogs, the answer is yes. Some dogs that have food allergies may get inflammation in their anal area. This makes it harder for dog glands to empty.

Feeding low-quality or high-fat content food can worsen the situation. What they eat can make a big difference.

Lack of Exercise

A dog that doesn’t get enough movement often has slower digestion. This affects bowel health and makes it harder for dog glands to work naturally. Regular walks, playtime, and active games are not just for fitness, they are also part of keeping your dog’s digestion healthy.

Body Structure

Body structure can play a part in dog anal gland issues. Smaller breeds have narrower gland ducts. This makes it difficult for fluid to pass through. Older dogs may also have digestive issues, making them vulnerable to anal gland issues, too.

How to Relieve Dogs' Anal Glands

If your dog is uncomfortable, you will want to know how to relieve dogs anal glands quickly. Visiting your vet can help you out as they can give your dog professional care.

In case the pain does not hurt much, a warm compress should be used. Apply it to the region for a few minutes to minimize the swelling and to promote spontaneous release.

To help during recovery, the WOPet Guardian Dog Treat Dispenser with Camera is useful. You can give treats and monitor your dog even if you are not home.

How to Help Dog Express Glands Naturally

Natural expression is possible for some dogs with the right care and attention. Adding fiber to meals can make stool firmer. This helps the glands empty on their own.

Daily walks and play also help. If your dog does not drink enough water, this can make the stool dry and hard. Here is a helpful guide on how to get your dog to drink more water. Good hydration keeps digestion healthy.

If you are wondering how to help dog express glands naturally, focus on diet, hydration, and regular activity.

Dog Swollen Anus Treatment at Home

If you notice swelling, it may be from irritation or infection. If it isn’t severe, you can try dog swollen anus treatment at home.

Use pet-safe wipes to gently wipe their anal areas. It is important not to use any products that are intended for humans, as the chemicals can harm them. Using a warm compress is also a good option to reduce swelling.

However, if the pain or swelling is more severe, doing the treatment at home will no longer be effective. Visit a vet immediately, as they will be able to deal with it better.

Best Dog Food for Anal Gland Issues

Finding the best dog food for anal gland issues makes a big difference. Choose food with quality protein and enough fiber. Avoid fillers and artificial ingredients.

Pumpkin and sweet potatoes in meals can also help make the stool more solid. This can support natural gland expression.

A routine feeding schedule is also important. An automatic feeder like the WOPet Heritage View Feeder with Camera and Dual Bowls ensures your dog eats on time, even when you are busy.

Preventing Anal Gland Problems

It is always a good idea to prevent rather than to treat. Making their diet healthy, ensuring they get proper exercise, and providing them with proper hydration are key steps.

Your dog can get hydration with a ceramic water fountain for pets, as they prefer running water over still water in a bowl.

Routine vet checks also help spot problems early. Groomers can sometimes notice early signs of dog anal gland issues before you do.

What to Avoid When Caring for Anal Glands

It is possible to learn how to check dogs anal glands, but not doing it properly can worsen the situation and even cause additional injury. Moreover, this is only an option when the discomfort is mild. Taking your dog to your vet is always the best solution to ensure proper care for your dog.

It is also vital not to overlook symptoms. Although not all the symptoms may seem serious, they may also be warning signs that you should not overlook. If you don’t look into it straight away, you can risk your dog experiencing more discomfort that would need more to treat.

The kind of food is also another important factor. Your pets might also be adversely affected by low-quality food that may have fillers, artificial flavors, or excess fat in it. Feeding on unhealthy food results in owners seeking means to clear overfilled dog anal glands. Stick to healthy meals that support digestion.

Also, avoid using human soaps or creams on your dog’s rear area. They have the ability to irritate the skin and also worsen swelling. When cleaning in the anal area, always use products designed to cater to dogs.

When to See a Vet

If your dog’s pain gets worse, then home treatment will no longer work. If the swelling increases or you notice bleeding, pus, or strong odors that don’t go away, it is time to go to the vet. These symptoms require quick treatment, which can only be given by your vet as they have the proper knowledge.

In case the issue continues, your vet may need to do more testing. Vets may suggest changing their diet, examining allergies, or other supplements that could make digestion easier to your dog. With these, your dog is sure to start feeling better again and start playing around.

However, if the problem gets too severe, then surgery might be the only option left. While this is rare, some dogs have chronic dog anal gland infections that cannot be treated by other methods.
