White Stuff Coming Out Of Dog’s Bum: What Exactly Does It Mean?


Well, if you notice a white liquid stuff in your dog’s bum, it’s likely the just the normal anal sac discharge. However, if the discharge is pus-like, it could be a case of anal gland infection or abscess. Broken gravid segments of tapeworm (proglottids) may also explain the white rice-like stuff in your dog’s bum. Also, a clear or white mucus in a dog’s poop or bum is indicative of colitis.

Seeing some white stuff in your dog’s bum whether it’s in a solid or fluid form might leave you worried about what is going on with your canine friend. It’s normal to want to understand what these white stuff are exactly and whether they will require any medical attention.

You have to ensure that the exact source of the white stuff coming out of your dog’s bum is actually the anus because female dogs naturally have white discharge in their heat period. The same may be said about pyometra but yellow, green, or brown discharge are also common in this condition. In male dogs, a white, yellow, or green-tinged fluid known as preputial discharge can leak from the space between the prepuce and the penis.

Throughout this article, we’ll delve deep into the various reasons for this occurrence, how to differentiate between normal and concerning secretions and practical steps you can take to address the situation. So, buckle up and prepare to embark on this journey of understanding and caring for your four-legged companion better.

Normal Anal Gland Discharge

Dogs have two anal glands (or sacs) located at approximately 4 and 8 o’clock positions around the anus. These glands produce a smelly, oily substance that is usually a brown or gray color. However, in some instances, it can appear as a white discharge.

Anal glands are used for scent marking and communication with other dogs. When your dog defecates, these glands typically express a small amount of this fluid. Sometimes, if the glands are not expressed properly during defecation, they can become full and might release the fluid when the dog sits or is stressed.

If the glands become full or impacted, they might need manual expression. This can be done by a vet or a trained groomer. Anal gland impaction can be caused by various factors, including soft stools, inflammation, obesity, low fiber intake,  parasites, or infection. Anal sac issues might be observed when the dog scoots its bottom on the floor. The scooting behavior is the dog’s way of trying to relieve the pressure or discomfort from these glands.


The white stuff that you may sometimes see coming out of a dog’s rear end can indeed be tapeworm segments, and it’s one of the common indicators that your dog may be infested with tapeworms.

Tapeworms are flat, segmented parasites that can live in the intestines of many animals, including dogs. They belong to the cestode family. One of the most common ways dogs become infested with tapeworms is by ingesting fleas during grooming. Fleas can carry the tapeworm larvae. Once inside the dog’s intestine, the larvae mature into adult tapeworms. Dogs can also get tapeworms by eating infected rodents or other wildlife.

The white stuff you see is not the whole worm but segments of it. These segments are called proglottids, and they contain the worm’s eggs. As the tapeworm grows, these proglottids are shed and may be visible in the dog’s feces or around its anus. When fresh, they are usually moist and may look like tiny, moving grains of white rice. As they dry out, they can resemble sesame seeds.

Sometimes, these proglottids can be seen moving. This can be unsettling for dog owners, but it’s a clear indication of a tapeworm infestation.

While the presence of proglottids is a telltale sign, not every dog will display them visibly. Some dogs might scoot their rear on the ground, which can be due to irritation. However, scooting can also be a sign of other issues, such as impacted anal glands.

Ruptured Anal Gland Abscess

A ruptured anal gland abscess can explain a whitish-yellow discharge from a dog’s rear end, but it often appears as a mixture of blood, pus, and other exudates.

If the anal glands don’t empty properly, the thick fluid inside can become even thicker, leading to impaction. Bacteria can then infiltrate the impacted gland, leading to an infection and, subsequently, the formation of an abscess.

Dogs with anal gland problems often scoot their rears on the ground, lick or bite at the area, or may appear in discomfort when sitting. The area around the anus can be swollen or red. If an anal gland abscess ruptures, it can produce a whitish-yellow or bloody discharge.

Should you suspect your dog has an anal gland abscess or any anal gland issue, it’s crucial to see a veterinarian promptly. The vet can assess the situation, clean the area, prescribe antibiotics if there’s an infection, and provide guidance on preventing future issues.

Excessive Mucus Produced When The Colon Is Inflamed (Colitis)

The colon naturally produces mucus to assist in the movement of stool and to protect its lining. Normally, you wouldn’t see this mucus because it is produced in a moderate amount.

When the colon becomes inflamed (as in colitis), it may produce an excessive amount of mucus. This mucus can sometimes be seen in the feces or around the dog’s anus. The mucus is typically clear, but it can occasionally appear white possibly due to the thickness.

There are various reasons a dog might develop colitis. This includes dietary indiscretions, food allergies, infections (viral, bacterial, or parasitic), stress, inflammatory bowel disease, certain medications and toxins, tumors, trauma or foreign bodies, reduced blood flow (ischemic colitis), or unknown reasons (idiopathic).

Apart from mucus in the stool, dogs with colitis might also display other symptoms such as diarrhea, blood in the stool, frequent and small amounts of feces, straining to defecate, and discomfort or pain.

Depending on the cause, treatment can range from dietary changes to antibiotics or anti-inflammatory medications. Chronic cases might require more specialized interventions.

Is It Really An Anal Discharge?

When dog owners notice a discharge or substance near their pet’s rear end, it can be easy to assume it’s originating from the anus when it might be from their genital areas. Both male and female dogs can produce discharges that are unrelated to their digestive or anal gland systems:

Vaginal Discharge During Heat (Estrus)

Female dogs, particularly those that are not spayed, go through estrus or a heat cycle. During this cycle, it’s typical for there to be some vaginal discharge.

The discharge during the initial stage (proestrus) is usually bloody. As the heat cycle progresses to the estrus stage, the discharge can become clearer, sometimes with a straw-like color. It’s also common for the female’s vulva to be swollen during this period.

This is a natural process, and no treatment is needed unless there’s an abnormal amount of discharge, foul smell, or if the dog seems to be in discomfort, which might indicate an infection or other medical issues.


Pyometra is a severe, life-threatening condition where the uterus fills with pus. It often occurs several weeks after the estrous cycle and can happen in any intact female dog.

A dog with pyometra may have a white, yellow, or green pus-like discharge from her vaginal orifice, drink excessively, urinate frequently, and become lethargic. Sometimes the cervix is closed, leading to a “closed pyometra” where there’s no noticeable discharge, but the dog becomes rapidly ill due to the accumulation of pus inside the uterus.

Pyometra is an emergency and requires immediate veterinary attention. The most common treatment is the surgical removal of the uterus and ovaries (spaying). In some cases, especially if detected early, vets may consider medical management, but surgery is generally the safest and most effective treatment.

Preputial in Male Dogs

Preputial discharge is a natural secretion that accumulates on the genitalia. In male dogs, it’s found on the penis and can sometimes be seen in the sheath area. Preputial discharge can be pale yellow to greenish. It’s not unusual to see a small amount of this secretion, especially when the dog is relaxed.

Composed of dead skin cells, oils, and other bodily fluids, preputial fluid acts as a lubricant and plays a role in maintaining genital hygiene.

In general, a small amount of preputial discharge isn’t concerning. However, excessive preputial fluid, changes in consistency, or the presence of blood can be indicative of infections, injuries, or other medical issues and should be checked by a vet.

When To Worry About Your White Stuff Coming Out Of Dog’s Bum

Noticing any unexpected discharge from your dog’s rear end can be concerning. While some discharges are normal or benign, others can be indicative of health issues. Let’s explore when the appearance of “white stuff” from your dog’s bum should be a cause for concern.

1. Consistency & Appearance

Pus-like Discharge: A thick, white, or bloody pus-like discharge can indicate an infection or abscess, especially if it’s accompanied by a foul odor. It could also indicate pyometra but dogs with pyometra may also have yellowish, or green discharge

Rice-like Segments: If the discharge looks like small, flat, white segments resembling grains of rice, it’s likely segments of tapeworms. This is a clear indication of a parasitic infection.

2. Accompanying Symptoms

Scooting: Dogs may scoot or drag their rear ends on the ground. While occasional scooting can be harmless, frequent scooting can indicate anal gland issues, parasites, or other problems.

Excessive Licking: If your dog is frequently licking its rear end, it can be a sign of discomfort, irritation, or infection.

Swelling or Redness: Visible swelling or redness around the anus can indicate inflammation, infection, or abscess formation.

Behavioral Changes: A dog that becomes lethargic, refuses to eat, or shows signs of pain should be checked by a vet, even if the discharge is the only other symptom observed.

3. Duration and Frequency

While an isolated incident may not be a cause for alarm, if you notice the white discharge consistently over several days or repeatedly over a short period, it’s worth a vet visit.

4. Other Considerations

Age & Gender: Puppies may be more susceptible to certain parasitic infections. Female dogs might have vaginal discharges that can be mistaken for anal discharge, especially if they’re in heat.

Diet & Environment: Dogs that have access to raw meats or potentially contaminated food sources may be at a higher risk for parasites. Similarly, dogs that are frequently around other animals or in environments like dog parks can be exposed to various parasites or infections.

When to Seek Veterinary Attention

Immediately: If the discharge is accompanied by significant behavioral changes, visible distress, or if there’s blood mixed with the discharge.

Within a Few Days: If the discharge persists over several days, even without other concerning symptoms.

For Routine Check-Up: If you’ve noticed occasional white discharge but aren’t immediately concerned, mention it during your dog’s next routine vet visit.

How To Keep Your Dog’s Anal Glands Healthy

Keeping your dog’s anal glands healthy is essential for their overall well-being. If these glands become impacted or infected, it can cause discomfort, and pain, and even lead to more severe health issues. Here are seven ways to ensure your dog’s anal glands remain healthy:

1. Regular Vet Check

Scheduling routine visits to your veterinarian is essential for keeping an eye on your dog’s overall health, including its anal glands. Veterinarians can manually express the glands if needed and inspect for any signs of impaction, infection, or other abnormalities. Regular checks, especially for breeds more prone to anal gland issues, are crucial for early detection and prevention.

2. Feeding Your Dog Fiber-rich Food

Diet plays a vital role in the health of your dog’s anal glands. A fiber-rich diet ensures that your dog produces firm stools, which can naturally compress the anal glands during defecation. This natural expression helps in preventing the build-up of secretions in the glands, reducing the chances of impactions.

3. Monitor for Abnormal Signs

Always be observant of your dog’s behavior. If they are scooting their rear on the floor, licking their anal region excessively, or if you detect a strong, foul odor, these can be indicators of anal gland issues. Addressing these signs early on can prevent more severe complications down the line.

4. Keep A Clean Environment

Maintaining hygiene is paramount. Ensure that your dog’s living environment is clean to reduce the risk of infections. After defecation, check the area around their anus to make sure there’s no residue. Using pet-friendly wipes can be beneficial in keeping the region clean. This not only aids in anal gland health but also overall hygiene and comfort for your dog.

5. Maintain a Healthy Weight

A dog’s weight significantly impacts its overall health, including the anal glands. Overweight dogs might face difficulty in naturally expressing their anal glands due to added pressure. Also, a healthy weight ensures regular bowel movements, further aiding in the natural expression of the glands. Work with your vet to determine an ideal weight for your dog and stick to a balanced diet and exercise routine to maintain it.

Diagnosis, Treatment And Prevention Of Anal Gland Infection In Dogs

Anal gland infections, or abscesses, are usually identified by redness, swelling, and sometimes a discharge near the anus. A veterinarian will typically perform a physical examination and may express the glands to analyze the fluid for signs of infection.

Treatment typically involves manually expressing the anal glands and flushing them out. If an abscess has formed, it may need to be drained. In many cases, antibiotics and anti-inflammatory medications are prescribed. In severe or chronic cases, surgical removal of the anal glands may be considered.

Regular vet checks, a fiber-rich diet to ensure firm stools for natural gland expression, and maintaining a healthy weight can prevent issues. Regularly inspecting the area for signs of redness, swelling, or discharge can help in early detection and treatment.

Diagnosis, Treatment, And Prevention Of Tapeworm Infection In Dogs

Tapeworm segments, which look like small, flat white grains (similar to rice), can be found in the dog’s feces or around their anus. A stool sample may be analyzed by a veterinarian for a definitive diagnosis.

Parasitic tapeworm infection be treated by oral or injectable medications that kill the tapeworms. Common medications include praziquantel, epsiprantel, and fenbendazole. It’s crucial to follow the vet’s recommended dose and ensure the complete treatment course to prevent recurrence.

Regular deworming is essential, especially if your dog is at a higher risk of tapeworm infection (e.g., they’re outdoors often, have had fleas, or are known to scavenge). Your veterinarian can suggest a suitable deworming schedule based on your dog’s lifestyle and risk factors.

Tapeworms are commonly transmitted by fleas. Thus, effective flea control is the primary preventive measure. Regularly administer flea treatments as recommended by your vet. Additionally, discourage your dog from eating raw meat or scavenging, as these can be sources of tapeworm infection.

Diagnosis, Treatment, And Prevention Of Colitis In Dogs

Colitis, or inflammation of the colon, can result in frequent, small-volume diarrhea with mucus and blood. To diagnose colitis, a veterinarian might take a detailed history, conduct a physical exam, analyze fecal samples, and perform diagnostic imaging like x-rays or ultrasound.

The treatment of colitis depends on its cause. Dietary changes, including transitioning to a highly digestible diet or a hypoallergenic diet, might be suggested. Anti-inflammatory medications, antibiotics, or other specific treatments might be prescribed based on the cause of the colitis.

Ensure your dog has a balanced diet and avoid sudden changes in their food. Regular vet checks can help identify and manage potential gastrointestinal issues early on. Keeping your dog away from ingesting foreign objects, toxic substances, or spoiled food can also prevent certain causes of colitis.

Anatomy Of Dog’s Anus

The dog’s anus and surrounding area are anatomically intricate and have multiple components designed to facilitate the elimination of waste and communicate with other dogs. It is the external opening of the rectum, which is the final part of the large intestine.

Anal Sphincter

The anus is surrounded by two sets of muscles: the inner and outer anal sphincters.

Internal anal sphincter: This is the innermost ring of muscle surrounding the rectum just before the anus. It is involuntary and is always contracted unless defecation occurs.

External anal sphincter: Surrounding the internal sphincter, this muscle is under voluntary control. This allows the dog (and other mammals) to control when they defecate.

Anal sacs (or anal glands)

These are two small pouches located on either side of the anus at approximately the 4 o’clock and 8 o’clock positions. They produce a smelly, oily substance that is used for scent marking. When dogs defecate, this substance can be squeezed out onto the feces, which helps them mark their territory. Sometimes these sacs can become impacted or infected, requiring manual expression or medical treatment.

Perianal area

This is the skin and tissue surrounding the anus. In some male dogs, especially those that haven’t been neutered, perianal tumors might develop around this area.

Dog Anus White Bumps

White bumps around a dog’s anus could be indicative of impacted, infected, or abscessed anal glands. What you are seeing could also be a cyst or perianal tumor. It’s essential to consult a veterinarian for a proper diagnosis and treatment plan.

Final Thoughts: White Stuff Coming Out Of Dog’s Bum

The world of canine health can, at times, present bewildering signs that leave dog owners puzzled and anxious. The appearance of white stuff or discharge from your dog’s bum is one such indicator. While many instances point towards natural processes or minor conditions, it’s paramount to remain vigilant about any changes, especially when they persist or are accompanied by other symptoms

The white discharge from a dog’s anus does not necessarily indicate any issues but the same cannot be said for the case of anal gland infections, where the glands produce a thick pus-like secretion. Tapeworms, another common culprit, shed segments that resemble grains of rice, adding to the list of potential explanations. Then there’s colitis, an inflammation of the colon, which can manifest as clear or white mucus in the feces.

Female dogs in heat or those suffering from conditions like pyometra can also exhibit white discharge, while in male dogs, preputial discharge , a natural secretion, can be occasionally observed.

Given the variety of potential causes, treatment should be tailored to the specific condition. Anal gland infections might require antibiotics or minor surgical interventions. Tapeworm infestations can be addressed with deworming medications. For dogs with colitis, changes in diet and possibly anti-inflammatory medications are the go-to solutions. Meanwhile, pyometra in female dogs is a serious condition that demands swift veterinary attention and potentially, surgery. While preputial discharge in male dogs is natural, maintaining regular hygiene is always a good practice.

Ultimately, it’s evident that the white stuff emanating from a dog’s bum can stem from multiple sources, each requiring a unique approach to management and treatment. Being vigilant and maintaining regular check-ups with your veterinarian ensures that your dog remains in optimal health, regardless of the underlying cause.
