Mucus in Dog Poop: Causes and Treatment

What Does Mucus in Dog Poop Look Like?

Observing your dog’s poop can provide valuable insights into their well-being.

Before cleaning up, it’s advisable to quickly inspect the stool to ensure it appears normal. Mucus is a frequent occurrence in dog feces and typically manifests as a glossy slime, transparent gel, or a mucous-like substance encasing the stool. If you notice mucus in your dog’s stool, it’s crucial to investigate the potential underlying causes.

Is Mucus in Dog Poop an Emergency?

The presence of a small amount of mucus in a dog’s stool shouldn’t cause alarm. However, an excessive quantity of mucus in your dog’s feces could signal an underlying medical issue requiring veterinary attention. If you consistently observe mucus in your dog’s stool, or if there’s a significant amount present even on a single occasion, it’s advisable to contact your veterinarian.

In cases where your dog is very young, elderly, or has a pre-existing health condition, immediate consultation with your vet is necessary upon noticing any mucus in their stool.

Furthermore, mucus may accompany diarrhea or blood in the stool. If your dog experiences diarrhea accompanied by mucus or any presence of blood, prompt veterinary care is essential.

Causes of Mucus in Dog Poop

Various factors can lead to the presence of mucus in a dog’s stool, typically stemming from conditions that cause colitis or inflammation in the colon.

Here are some common disorders associated with mucus in dog stool:

  • Intestinal Infections: Bacterial, viral, and fungal infections such as E. coli, salmonella, parvovirus, and pythiosis can trigger mucus production in the stool. Dogs with GI infections often exhibit additional symptoms like diarrhea, vomiting, or loss of appetite, necessitating supportive care and specific medications to address the infection.
  • Parasites: Infestations by parasites like whipworms, tapeworms, and Giardia can result in mucus in the stool. Diagnosis via fecal exams guides appropriate deworming treatments.
  • Dietary Indiscretion: Ingesting foreign objects or unusual substances can disturb the GI tract, leading to mucus in the stool. While mild cases may resolve spontaneously, severe instances may require interventions such as medication, fluid therapy, or even surgery.
  • Change in Diet/Food Allergies: Sudden dietary changes can provoke mucus production in a dog’s stool, which often resolves by gradually reintroducing the original diet. Food allergies or intolerances may necessitate switching to hypoallergenic diets prescribed by a veterinarian.
  • Irritable Bowel Syndrome (IBS): Stress is a significant trigger for IBS flare-ups in dogs. Management involves stress reduction techniques, dietary modifications, and medications like sulfasalazine to alleviate symptoms.
  • Inflammatory Disorders: Inflammatory bowel disease (IBD) can manifest with mucus in the stool alongside weight loss, vomiting, or diarrhea. Treatment typically entails dietary adjustments and sometimes immunosuppressive medications.
  • Cancer: GI tract cancers can lead to mucus production in the stool. Treatment options range from surgical interventions to chemotherapy, radiation therapy, or palliative care.
  • Acute Hemorrhagic Diarrhea Syndrome (AHDS): AHDS, also known as hemorrhagic gastroenteritis, presents with bloody and mucous-laden stools resembling raspberry jam. Treatment includes supportive care, anti-nausea medications, fluid therapy, and antibiotics.

What To Do If Your Dog Is Pooping Mucus

If your dog consistently passes abnormal amounts of mucus in their stool or exhibits additional symptoms such as:

  • Decreased appetite
  • Weight loss
  • Vomiting
  • Diarrhea
  • Presence of blood in the stool
  • Signs of discomfort or pain

It’s essential to schedule a vet appointment promptly. These symptoms may indicate an underlying health concern that requires professional evaluation and treatment.


When addressing mucus in your dog’s stool, the veterinarian will commence with a comprehensive health history review and conduct a thorough physical examination.

To identify the root cause, they may conduct a series of tests, including:

  • Fecal examination
  • Blood tests
  • Urinalysis
  • Abdominal X-rays and/or ultrasound scans
  • Endoscopy
  • Intestinal tract biopsy


Treatment for mucus in your dog’s stool will be tailored to the specific diagnosis obtained from the tests conducted.

However, it often involves dietary adjustments, which may include transitioning to a new diet or a prescription diet.

Depending on the underlying cause, the veterinarian may prescribe anti-diarrheal medication, immunosuppressants, or antibiotics. Probiotics are often recommended as part of the treatment plan for mucus in stool.

Home Remedies for Mucus in Dog Poop

If your dog displays only a minor amount of excess mucus in their stool and is otherwise in good health (maintaining appetite, displaying happiness, remaining active, and without diarrhea), you may consider treating them at home before seeking a veterinary visit and diagnostic evaluation.

Short-term Bland Diet

Occasionally, switching to a highly digestible diet or introducing additional fiber to your dog’s diet can be beneficial. A homemade option such as boiled white meat chicken (skinless and boneless), white rice, and a teaspoon to a tablespoon (adjusted for the dog’s size) of canned pumpkin can serve as a suitable short-term diet for a few days.


In cases where a dog exhibits minor mucus in their stool and is otherwise healthy, treatment with medications may not be necessary. However, supplementation with probiotics may offer support. Look for probiotic products formulated specifically for dogs or seek recommendations from your veterinarian.

Living and Management

The resolution of mucus in a dog’s stool varies depending on the underlying cause, with some cases being transient and quickly resolving. However, conditions like inflammatory bowel disease (IBD) may lead to fluctuations in mucus presence, indicating the need for ongoing veterinary consultation.

Regular monitoring of your dog’s stool is essential for assessing their health status. Look out for any signs of mucus, blood, or diarrhea, as these may indicate underlying issues.

If you’re uncertain about the normalcy of your dog’s stool, don’t hesitate to contact your veterinarian for guidance. Providing photos can often assist in their assessment.
