Is your dog dragging their rear across the carpet or obsessively licking their behind? While it might seem amusing at first, these behaviors are often a cry for help—your dog's anal glands might be full. Every dog parent has likely witnessed the infamous 'scoot' during an inconvenient moment, perhaps while entertaining guests.  

That unmistakable behavior, combined with a distinctive fishy odor, isn't just your dog being quirky, it's their way of communicating discomfort that needs attention. Let's tackle this common but often misunderstood health concern with practical solutions to keep your furry friend comfortable and healthy. 

What Are Dog Anal Glands? 

Anal glands are two small, oval-shaped sacs located beneath the skin at the four o’clock and eight o’clock positions around a dog’s anus. Both male and female dogs have these glands, which secrete a unique, pungent fluid. The glands produce a distinctive fluid with an unmistakably pungent, fishy odor unique to each dog.

This fluid serves as a biological identifier for dogs, marking their stool with a distinctive scent that communicates health, age, and even reproductive status. Under normal circumstances, these glands express naturally when your dog has a bowel movement, as firm stool creates pressure on the anal sacs. 

Why Do Dogs Have Anal Glands? 

In the wild, this scent-marking helped dogs establish territory. Though the glands are considered vestigial in modern domesticated dogs, they still serve some purposes: 

  • Marking their territory by leaving their scent during defecation 

  • Communicating with other dogs 

  • Potentially helping with stool passage by providing lubrication 

How to Tell If Your Dog's Anal Glands Are Full

Recognizing the signs of full anal glands is key to early intervention. Dogs typically express their anal glands naturally during bowel movements. However, if the glands fail to empty properly, they can become full, leading to discomfort or infection. Watch for these telltale signs that your dog's anal glands need attention: 

Early Warning Signs 

  • Scooting or dragging their bottom across the floor 

  • Excessive licking or biting at their rear end 

  • A distinct fishy odor, even right after grooming 

  • Sitting uncomfortably or suddenly jumping up after sitting 

Progressive Symptoms 

  • Visible swelling or redness around the anal area 

  • Straining during bowel movements 

  • Changes in posture, especially while sitting 

  • Reluctance to sit or walk 

  • Behavioral changes, such as irritability 

What Causes Anal Gland Problems in Dogs? 

A number of factors can disrupt the normal function of a dog's anal glands, leading to discomfort and potential health issues. These factors include: 

Diet and Stool Quality 

  • Diets lacking sufficient fiber can lead to soft stools, which fail to exert enough pressure on the anal glands for natural expression. 

  • Deficiencies in essential vitamins and minerals can compromise the immune system and increase susceptibility to inflammation, which can contribute to anal gland issues. 

  • Inconsistent feeding schedules can disrupt digestion and lead to irregular bowel movements, affecting the natural expression of anal glands. 

Physical Factors 

  • Obesity increases the risk of anal gland issues by weakening surrounding muscles, reducing pressure during defecation, and potentially obstructing gland ducts with excess fat tissue. 

  • Small breeds are more prone to these problems due to anatomical factors, such as smaller ducts and less effective musculature. 

Health Conditions 

Professional Treatment Options for Full Anal Glands in Dogs 

When your dog needs help with anal gland issues, your veterinarian has several treatment paths available, ranging from simple expressions to surgical solutions. 

Immediate Care 

Your vet typically starts with the least invasive options, such as manual expression of the glands, medicated wipes or ointments for inflammation, and recommendations for dietary changes to improve stool consistency. 

Advanced Treatment 

If simple measures aren't enough, your vet may prescribe antibiotics for infections or anti-inflammatory medications to manage pain and swelling. 

Surgical Solutions 

In severe cases where other treatments haven't worked, surgical removal of the anal glands (anal sacculectomy) might be recommended. This is typically reserved for dogs with chronic infections, recurrent abscesses, anal gland cancer, or ongoing problems that don't respond to conservative treatment. 

When to Leave Anal Glands to the Professionals 

While you might be tempted to handle anal gland expression at home, this delicate procedure is best left to your veterinary team. Even with the best intentions, improper technique can lead to injury or make existing problems worse.  

Your vet's trained eye can spot early signs of infection or other complications while performing the expression safely. They'll also guide you on whether your dog needs regular maintenance expressions or if there are underlying issues that need addressing.  

When to Seek Immediate Veterinary Care 

Full anal glands aren't just uncomfortable, they can lead to serious complications if left untreated. While some dogs suffer in silence, certain signs should prompt an immediate call to your veterinarian.  

Watch for blood or pus around the anal area, severe swelling or redness, signs of pain during bathroom breaks, or persistent scooting and licking that leads to irritation.  

Some dogs might even show behavioral changes, such as refusing to sit or a significant loss of appetite. Don't wait if you notice these warning signs, early intervention can prevent painful abscesses and more serious medical issues that could require extensive treatment. 

How to Prevent and Care for Your Dog’s Anal Glands 

Smart prevention starts with proper nutrition and regular veterinary care. A high-quality diet with appropriate fiber content helps maintain firm stools that naturally express the glands during defecation. Regular exercise and weight management also play crucial roles.  

The key is staying alert to your dog's behavior – watch for signs of discomfort and address any allergies or skin sensitivities promptly. Regular wellness checks with your veterinarian can catch potential issues before they escalate. 

Protecting Your Pet's Health by Getting Pet Insurance 

While routine anal gland expressions may be generally affordable, complications such as infections or abscesses can lead to unexpected and expensive veterinary bills. 

In these situations, pet insurance can make a significant difference, helping you avoid the tough choices that come with rising medical costs. By covering the more intensive treatments, a comprehensive pet insurance plan ensures you can always prioritize your dog’s health without worrying about finances. 

In addition to illness and accident coverage, you have the option to add a non-insurance pet wellness plan that covers routine care, including anal gland expressions. These plans help with early detection and prevention, plus they give you the security of knowing you're covered if any complications pop up. 

With the right coverage, you can focus on keeping your dog healthy and happy without the added stress of unexpected veterinary expenses. 

The Bottom Line on Canine Anal Glands 

While the topic of anal glands might not be the most glamorous, understanding them is a crucial part of responsible pet ownership. By recognizing the signs of discomfort and seeking timely veterinary care, you can help your furry friend live a happier and healthier life.
