The Hidden Truth: How to Express a Dog’s Anal Glands Safely & Effectively

Published 20 June 2026

Every dog owner has heard the term—sometimes whispered, sometimes joked about—but the reality of how to express a dog’s anal glands remains a mystery for many. The topic is rarely discussed in casual pet conversations, yet it’s a critical aspect of canine hygiene and well-being. Anal gland issues are among the most common reasons dogs drag their rear ends, scoot across floors, or develop painful infections. Ignoring the problem can lead to discomfort, infections, or even surgical intervention. Yet, despite its importance, few resources break down the process with clarity, separating myth from medical fact.

The misconceptions begin with the word itself. "Expressing" sounds clinical, almost sterile, but in practice, it’s a hands-on task that requires precision, patience, and a deep understanding of canine anatomy. Some owners assume their dog’s glands will regulate naturally, while others fear the process is too invasive or risky. The truth lies somewhere in between: proper technique can be learned, and the benefits—ranging from preventing infections to improving your dog’s quality of life—are substantial. The key is approaching it with knowledge, not hesitation.

Veterinarians and professional groomers perform this procedure daily, yet the average pet owner often feels unprepared. The lack of transparency around how to safely express a dog’s anal glands stems from a combination of embarrassment and misinformation. Dogs, after all, are part of our families, and discussions about their most intimate functions are rarely framed as educational. But the consequences of neglect—from chronic infections to behavioral changes like excessive licking or biting—can be severe. This guide cuts through the stigma, offering a step-by-step breakdown of why, when, and how to address anal gland expression, backed by veterinary science and real-world experience.

The Complete Overview of How to Express a Dog’s Anal Glands

Anal gland expression is a natural process in dogs, but it’s one that many owners never witness unless a problem arises. These small, pea-sized glands—located on either side of the anus—secrete fluid during bowel movements to lubricate and mark territory. In some dogs, however, the glands become impacted, meaning they don’t empty properly. This can happen due to genetics (certain breeds like Cocker Spaniels and Dachshunds are predisposed), diet (low-fiber foods leading to hard stools), or simply the dog’s anatomy. When left unaddressed, impacted glands can swell, rupture, or become infected, causing pain, inflammation, and even abscesses.

The solution is straightforward in theory: manually express the glands to release the built-up fluid. However, the execution requires caution. Overzealous squeezing can damage the delicate tissue, while too little pressure may leave the glands partially full. The process also demands cleanliness—dirty hands or improper technique can introduce bacteria, leading to infections. For these reasons, many owners opt to leave it to professionals, but learning to do it at home can save time, money, and stress, especially for dogs prone to recurring issues. The goal isn’t just to relieve discomfort but to establish a routine that prevents future problems.

Historical Background and Evolution

The concept of anal gland expression isn’t new—it’s been a part of veterinary practice for decades, though the terminology has evolved. Historically, the glands were referred to as "scent glands" due to their role in canine communication, and their importance in marking territory was well-documented by ethologists studying animal behavior. Early veterinary texts from the mid-20th century described the glands as "accessory sex glands," highlighting their secondary role in reproduction and social signaling. However, as veterinary medicine advanced, the focus shifted to their functional health, particularly in domestic dogs where natural expression during bowel movements wasn’t always sufficient.

By the 1980s and 1990s, the rise of small-breed dogs—many of which have anatomical predispositions to glandular issues—led to a surge in cases requiring manual expression. Veterinarians began emphasizing the importance of regular checks, especially for breeds like Bulldogs, Pugs, and Shih Tzus, whose compact bodies often lead to impaction. The 21st century brought further refinement in technique, with groomers and vets advocating for a gentler approach to avoid trauma. Today, the procedure is taught in veterinary schools and grooming courses, but many pet owners still rely on trial and error—or avoid it altogether—due to lack of accessible information.

Core Mechanisms: How It Works

The anal glands are embedded in the tissue surrounding the anus, each connected to a duct that opens into the rectum. When a dog defecates, the pressure from the stool should naturally squeeze the glands, releasing their fluid. However, in some dogs, the stool passes too quickly or is too firm, leaving the glands partially full. Over time, the fluid thickens, and the glands become swollen and painful. The expression process involves applying firm but controlled pressure to the glands through the anus’s surrounding tissue, mimicking the natural squeezing that should occur during bowel movements.

Anatomy plays a crucial role in success. The glands are located at the 4 and 8 o’clock positions relative to the anus (if you’re looking at the dog’s rear). Using gloved fingers, the owner or professional applies pressure to these points, feeling for a small, firm bulge. The pressure should be steady and gradual—too much force can cause bleeding or rupture, while too little may not fully empty the glands. The released fluid is typically dark brown or greenish, with a strong, musky odor. Some dogs may resist initially, but with proper technique and a calm demeanor, the process becomes less stressful over time.

Key Benefits and Crucial Impact

Understanding how to express a dog’s anal glands isn’t just about addressing a specific issue—it’s about preventing a cascade of health problems that can affect your dog’s daily life. Dogs with impacted glands often develop a condition called "sacculitis," where the glands become chronically inflamed. This can lead to abscesses, fistulas, or even systemic infections if bacteria enter the bloodstream. Beyond physical discomfort, behavioral changes are common: dogs may scoot their rear ends on carpets, lick excessively, or show signs of pain when sitting. These symptoms are often the first red flags that something is amiss.

The long-term benefits of regular expression extend beyond immediate relief. Dogs with well-maintained glands are less likely to develop chronic infections, which can be costly and painful to treat. Additionally, preventing impaction reduces the risk of more invasive procedures, such as surgical removal of the glands—a last resort that should only be considered in severe, recurrent cases. For owners, the process also fosters a deeper understanding of their dog’s body, strengthening the bond through attentive care. When done correctly, anal gland expression is a simple yet powerful tool in maintaining your dog’s overall health.

"Anal gland issues are one of the most preventable yet commonly neglected problems in small-breed dogs. A few minutes of careful expression can save hours of veterinary visits and thousands in treatment costs." — Dr. Emily Carter, DVM, Canine Holistic Specialist

Major Advantages

• Pain Relief: Impacted glands cause significant discomfort, often leading to scooting or excessive licking. Expression alleviates pressure and reduces pain.
• Infection Prevention: Stagnant fluid in the glands is a breeding ground for bacteria. Regular expression lowers the risk of abscesses and infections.
• Behavioral Improvement: Dogs with healthy glands are less likely to exhibit irritable or anxious behaviors related to discomfort.
• Cost Savings: Treating chronic infections or surgical interventions is far more expensive than preventive expression.
• Long-Term Health: Consistent maintenance reduces the likelihood of recurring issues, promoting better overall well-being.

Comparative Analysis

Future Trends and Innovations

The future of anal gland care in dogs may lie in preventive technologies and less invasive techniques. Researchers are exploring dietary supplements designed to soften stools and naturally stimulate gland expression, reducing the need for manual intervention. Probiotics and fiber-rich additives are already being studied for their potential to improve glandular health, particularly in breeds prone to impaction. Additionally, wearable devices or smart collars that monitor bowel movements and glandular activity could provide early warnings for owners, allowing for timely expression before issues escalate.

On the procedural side, innovations in veterinary tools—such as specialized expression devices or laser therapy for chronic inflammation—may make the process even safer and more efficient. While these advancements are still in early stages, the growing emphasis on holistic and preventive care suggests that anal gland health will become a more integrated part of routine canine wellness. For now, the most effective approach remains a combination of proper diet, regular expression, and vigilant observation—but the horizon holds promising developments for pet owners.

Conclusion

Learning how to express a dog’s anal glands is not just a practical skill—it’s a responsibility that comes with pet ownership. The stigma surrounding the topic often leads to delayed care, but the reality is that a few minutes of attention can prevent weeks of discomfort and veterinary bills. The key is approaching the process with confidence, starting with a clean environment, proper gloves, and a calm dog. For first-timers, enlisting the help of a veterinarian or groomer for a demonstration can make all the difference. Over time, the task becomes second nature, and the bond between owner and dog strengthens through this act of attentive care.

Remember, every dog is unique. Some may require expression every few months, while others need it only when symptoms arise. Pay attention to your dog’s behavior—changes in posture, excessive licking, or scooting are clear signals that the glands need attention. By taking charge of this often-overlooked aspect of canine health, you’re not just preventing pain; you’re ensuring your dog lives a happier, more comfortable life. The anal glands may be small, but their impact on your dog’s well-being is anything but.

Comprehensive FAQs

Q: How often should I express my dog’s anal glands?

A: Most dogs only need expression if they show signs of impaction, such as scooting or excessive licking. However, breeds prone to issues (like Cocker Spaniels or Dachshunds) may benefit from preventive expression every 3–6 months. Always consult your vet for a tailored schedule based on your dog’s health history.

Q: What if my dog’s glands are too swollen to express?

A: If the glands are severely swollen or painful, forcing expression can cause trauma. In such cases, apply a warm compress to reduce inflammation and contact your vet immediately. They may prescribe anti-inflammatory medication or recommend a different approach, such as a soft stool diet to encourage natural emptying.

Q: Can I use human lubricant for expressing my dog’s glands?

A: No, human lubricants—especially those containing parabens or fragrances—can irritate your dog’s sensitive tissue. Use only pet-safe, water-based lubricants or plain mineral oil. Always check with your vet for product recommendations.

Q: What does healthy anal gland fluid look like?

A: Normal gland fluid is dark brown or greenish, with a strong but not foul odor. If the fluid is yellow, white, or has a pus-like consistency, it may indicate an infection. In such cases, seek veterinary care promptly.

Q: Is it safe to express a dog’s glands if they’ve never been done before?

A: For first-time owners, it’s safest to have a veterinarian or experienced groomer demonstrate the technique. Attempting it without guidance can lead to injury or incomplete expression. Many vets offer quick training sessions for owners unsure about the process.

Q: What should I do if my dog bites or resists during expression?

A: If your dog is anxious or aggressive, use a muzzle (if trained) or ask a second person to hold them gently but firmly. Never force the process—stop if your dog is in distress and try again later. Positive reinforcement (treats or praise) can help associate the experience with rewards over time.

Q: Can diet changes help prevent anal gland issues?

A: Yes, a high-fiber diet promotes softer stools, which naturally stimulate gland expression. Foods like pumpkin, sweet potatoes, or commercial high-fiber dog foods can be beneficial. Always introduce dietary changes gradually and consult your vet to avoid digestive upset.

Q: Are there any home remedies for anal gland expression?

A: While no true "home remedy" replaces proper expression, some owners find that adding psyllium husk to their dog’s food or offering coconut oil can help soften stools. However, these should not replace manual expression if impaction is present. Always prioritize veterinary advice for persistent issues.

Q: When should I consider surgical removal of the anal glands?

A: Surgery is a last resort for dogs with chronic, recurrent infections that don’t respond to other treatments. It’s typically recommended only after multiple failed attempts at medical management. Discuss the risks and benefits with your vet, as surgery can lead to complications like incontinence or scarring.

Q: Can I express my dog’s glands if they’re on medication?

A: Some medications (e.g., steroids or antibiotics) may affect glandular health or healing. Always check with your vet before expressing if your dog is on prescription drugs. They may advise adjusting the timing or approach based on the medication.
