Sometimes your dog starts doing things that look funny at first, like dragging its backside on the floor or licking under its tail again and again. Most people just laugh it off or think it’s a one-time thing. But when it keeps happening, you start wondering, is something wrong?

For many dog parents, this is how it begins. What seems like a small issue turns out to be a painful problem with the dog’s anal glands. In India, where home remedies are often tried before consulting a veterinarian, this kind of issue can go unnoticed until the dog becomes clearly uncomfortable.

Anal gland infections are more common than you’d expect. They can cause pain, swelling, a bad smell, and in some cases, even pus or bleeding. Most pet parents don’t even know these glands exist until their dog has trouble. But knowing the early signs can really help—and sometimes even save a trip to the vet.

This blog is for anyone who wants to understand what’s going on and what can be done, without the medical jargon. Simple advice, explained in plain language, so you know when to watch, when to treat at home, and when it’s time to see a professional.

Because caring for your dog shouldn’t be confusing, and it starts with noticing the little things.

Key Takeaways

• Anal gland infections in dogs often stem from impaction and can lead to serious complications if untreated, including abscess formation.

• Symptoms to watch for include scooting, licking the rear end, swelling around the anus, and foul odors. Early detection is crucial.

• Preventive measures include regular vet check-ups, a high-fiber diet, weight management, and proper grooming to maintain anal gland health.

An anal gland infection develops when the anal sacs have become impacted and then infected, which can result in great pain, usually associated with anal sacculitis. The events include:

• Not emptying their anal sacs properly.

• The fluid has become thickened and obstructed the openings, causing impaction.

• Bacterial growth from the impaction.

• May develop an abscess inside the anal sacs.

Impacted sacs are when the glands have become plugged, swollen, stretch, are painful, and may have a higher risk for bacterial infection or an abscess.

Signs of an anal gland infection can be quite obvious. Typical signs of anal sac disease are scooting, excessive licking of the area, and odor. Swelling around the anus, pain during defecation, and odor are typical signs. In extreme cases, the infected anal glands will express bloody pus, indicating more widespread infection. Left untreated, anal gland infections can result in serious complications like abscess and severe pain.

Sac disease in dogs is a broader category that includes impaction, infection, abscess, and cancer of the anal sacs. Regular monitoring for symptoms and frequent veterinary visits help maintain healthy anal glands and prevent infections to reduce recurrence. Detecting and treating issues early helps avoid discomfort and complications.

Anal sac disease usually starts with an impaction and can progress to an infection or an abscess. Material becomes dried out or poorly inflamed enough that it causes impaction of the anal sacs. Risk factors associated with anal gland issues in dogs include impaction, obesity, diet quality, exercise, and overall health conditions.

Occasionally the cause is food allergies or poor dietary quality with food that causes variable stool consistency all the time which contributes to problems with the anal sacs. Sadly, some breeds (e.g., Cocker Spaniel, Cavalier King Charles Spaniel, Springers, German Shepherds, and dachshunds) and older dogs are at greater risk of developing anal sac diseases (including anal sac adenocarcinoma - some of which can be terrible diseases); older dogs were more likely to develop advanced anal sac disease. Risk factors can address lack of proper diet and weight management which reduces the chance of anal gland problems from happening in the first place so you can make a diagnosis of anal sac disease.

In most cases, dogs handle their anal glands on their own—you wouldn’t even notice. It’s all part of their natural process, especially when they poop. But when something’s off, the signs are usually hard to miss.

One of the first things many dog parents see? That odd little dance—your dog scooting its backside across the floor like it’s trying to clean something off. It might make you laugh the first time, but it’s often their way of showing something’s bothering them. Then comes the licking. Not the casual kind. This is obsessive, focused attention to their rear end—licking, biting, even turning around quickly like they’re trying to fix the problem themselves.

There’s also that smell. It’s not like anything else—a sharp, fishy stink that tends to linger in the room. By the time that shows up, there’s a good chance the glands are swollen or infected. In some cases, you’ll see a little puffiness or redness near the anus, maybe even discomfort when they try to sit.

Here’s the thing: the earlier you catch it, the better. It’s like spotting a small leak before it becomes a flood. I’ve had friends who thought their dog’s scooting was just itchy skin, only to find out it was an abscess that needed draining. And that isn’t cheap—or comfortable for the dog.

So if your pet starts acting strange around their rear end—don’t ignore it.

Call your vet. Talk to them. It might be something small, or it might need treatment. Either way, it’s better to act early than wait for things to get worse.

Generally, when differentials for anal gland infections are made, it requires a digital rectal examination conducted by a veterinarian. This examination helps the veterinarian to look for signs of impaction, infection, and abscessation. If tumors or serious infections are suspected, other diagnostics such as imaging and/or potential biopsies may be warranted. Imaging or biopsies are also helpful in diagnosing anal sac adenocarcinoma, a more severe type of cancer of the anal sacs than other anal sac diseases.

If symptoms such as painful defecation or an inappropriate discharge occur, further diagnostic testing is often pursued. The veterinarian may even be able to express the dog's impacted anal sacs, if the anal sacs are not severely impacted.

Diagnostics are most necessary to manage care and treatment effectively.

Often the first step in disturbing anal gland infections is manual expression of the anal glands, a procedure usually performed by a veterinarian of a special interest in veterinary medicine. If infection is diagnosed, veterinary medicine will prescribe  oral antibiotics to restrict the amount of bacterial growth in the anal glands. Pain relief medication can also be administered to assist the animal in treating the pain of the infection.

In advanced cases of anal gland infection, surgical intervention could be needed. Surgical intervention could mean removing the anal sacs: a procedure called an anal sacculectomy, which will protect animals from further anal gland health issues. Surgery is considered in cases when other treatments have not worked, or if the dog has multiple anal sac abscesses or tumors. Anal sac disease treated by surgery can relieve the dog of continuous but treatable problems. Repeated infections or surgical interventions can create scar tissue that limits the options for future treatment.

Preventing anal gland infections involves:

• Regular veterinary check-ups to detect potential issues early.

• Adding more fiber to the diet of dogs that frequently experience anal sac impaction, as recommended by veterinarians.

• Maintaining a healthy diet to prevent changes in stool consistency that can lead to anal sac problems.

Regular exercise, maintaining a healthy weight, and routine grooming and cleaning of the anal area help prevent infections. Regular examination and maintenance of anal glands can catch issues before they become serious.

A diet rich in fiber benefits anal sac health by promoting proper stool consistency, which naturally expresses the anal glands during bowel movements and helps manage anal sac contents and anal sac fluid. This kind of diet supports healthy digestion and proper stool formation.

Diarrhea or soft stools can hinder the natural expression of anal glands. A fiber-deficient diet can lead to anal gland issues, while well-formed stools facilitate muscle contractions that naturally clean the anal sacs during bowel movement.

Healthy weight maintenance is essential since overweight dogs tend to be more prone to anal gland issues due to reduced pressure during defecation. Obesity lowers the pressure needed to naturally express the anal glands.

Consulting a veterinarian for a weight-loss strategy is important for overweight dogs. Maintaining a healthy weight helps prevent anal gland problems and supports overall well-being.

Surgery may be necessary for chronic problems that don’t respond to other treatments, including recurrent abscesses or tumors in the anal glands. Veterinarians might suggest anal gland removal if other treatments fail.

An anal sacculectomy eliminates future gland-related health issues, improving the quality of life for dogs with chronic conditions. However, post-surgery, some dogs might experience changes in bowel habits, fecal incontinence, or nerve damage leading to chronic issues.

Untreated anal gland infections can lead to anal gland impactions, infection, or abscesses, causing extremely painful discomfort. An untreated infection may result in an anal sac abscess that can burst and release pus from the anal opening; this pus or fluid may appear greenish yellow, indicating infection.

Severe untreated infections can become systemic, requiring additional treatment and intensive medical intervention. The infection can spread to surrounding tissues, causing severe damage. Timely treatment prevents these serious health issues.

Regular veterinary check-ups help maintain healthy anal glands by catching potential issues early. A fiber-rich diet, including foods like pumpkin and sweet potatoes, enhances stool consistency, aiding in natural gland expression.

High-fiber ingredients reduce inflammation in the digestive tract, promoting better anal gland function. High-fiber diets help dogs with anal gland issues by firming stools and facilitating natural gland expression.

Monitoring symptoms like dog scooting and excessive licking is crucial for early intervention in anal gland issues.

In summary, understanding and managing anal gland infections in dogs is crucial for their overall health and well-being. Recognizing the symptoms, seeking timely veterinary care, and implementing preventive measures can significantly improve your dog’s quality of life.

By maintaining a healthy diet, ensuring regular exercise, and keeping up with veterinary check-ups, you can help prevent anal gland issues. Remember, early detection and intervention are key to keeping your dog’s anal glands healthy and free from infection.

How do you know if your dog needs his glands squeezed?

If your dog is scooting, licking their rear excessively, or showing signs of discomfort near the anus, it may be time for gland expression. A fishy odor is another common sign. These behaviors indicate full or impacted anal glands that need attention.

Can dogs clear their own glands?

Some dogs can naturally express their anal glands through regular bowel movements. However, smaller breeds and dogs with soft stools may have trouble doing so, which can lead to impaction or infections requiring manual expression by a vet or groomer.

How do I stop my dog from smelling like fish?

A fishy smell in dogs often signals full or leaking anal glands. Regular vet checks, high-fiber diets, and consistent bowel movements can help. If the odor persists, your vet may need to express the glands or check for infection or other issues.

How can I treat my dog’s glands at home?

If your dog’s glands are only mildly full, you can try increasing fiber in their diet to promote natural expression. Warm compresses on the anal area may help too. Manual expression should only be done if you're trained, as improper technique can cause harm.

How do dogs naturally empty their glands?

Dogs typically express their anal glands during defecation when firm stools apply pressure. Some dogs also release gland fluid when scared or stressed. Regular, well-formed stools are key to promoting natural gland function and avoiding buildup or infections.

At what age do dogs need their glands expressed?

There’s no specific age, but some dogs begin having issues as early as a few months old. Smaller breeds and dogs with soft stools are more prone. Your vet can advise if expression is needed based on your dog's behavior and history.

Can dogs express their own glands by licking?

No, licking the area won’t actually express the glands. Dogs may lick due to discomfort, irritation, or fullness, but manual or natural expression during bowel movements is needed to fully empty them. Persistent licking is a sign you should consult a vet.

What is the treatment for anal sac disease in dogs?

Treatment includes manual expression, antibiotics for infection , anti-inflammatory medications , and sometimes surgery in severe or recurring cases. Early intervention is crucial. Your vet may also suggest a diet change to help prevent future gland issues.

How can I treat my dog’s swollen anus at home?

Apply a warm compress several times daily to reduce swelling and discomfort. Adding fiber to your dog's diet may help. Keep the area clean and monitor for pus or bleeding. Seek vet care if swelling worsens, or signs of infection appear.

What is the best home treatment for a ruptured anal gland abscess in dogs?

Clean the area with a gentle antiseptic and apply a warm compress to encourage drainage. Do not squeeze or probe the abscess. Keep your dog from licking the area and consult a vet immediately, as antibiotics and professional care are often necessary.

How can I treat a swollen anus in dogs?

Use warm compresses, keep the area clean, and prevent your dog from licking. A high-fiber diet may support regular bowel movements, which helps reduce swelling. However, if swelling persists or your dog is in pain, seek veterinary treatment right away.

Can food cause anal gland issues in dogs?

Yes, low-fiber or poor-quality diets can lead to soft stools, which don’t help naturally express glands. A diet high in fiber promotes firm stools that naturally empty the glands. Allergies and food sensitivities can also contribute to inflammation or poor digestive health.

What is an anal sac abscess in dogs?

An anal sac abscess is a painful, infected swelling caused by blocked glands. It can rupture and drain pus or blood. Symptoms include scooting, pain when sitting, and swelling near the anus. Immediate veterinary care is needed to prevent further complications.

What does a perianal abscess in dogs look like?

A perianal abscess appears as a red, swollen lump near the anus, sometimes oozing pus or blood. It may cause your dog pain or reluctance to sit. Pictures show inflamed tissue, possible hair loss around the area, and visible drainage if ruptured.

Why is my dog’s anus red and irritated?

Redness and irritation can result from full anal glands, allergies, parasites, or infections. Constant licking or scooting may worsen it. Use a mild antiseptic to clean the area and prevent licking. Persistent redness should be evaluated by a vet.
