What are the common causes of fecal incontinence?

Fecal incontinence has many possible causes, including intestinal infection, abnormal anal or rectal function, nerve or muscle problems, or systemic disease. A vet will evaluate the cause through fecal testing, imaging, and physical examination and recommend the appropriate next steps.

How can I observe and record symptoms at home?

It is recommended to record the time of onset, bowel movement frequency, and stool consistency, film bowel movements or abnormal behavior, and bring a fresh stool sample to the clinic. This information helps the vet make a faster assessment.

When should I take my pet to the emergency vet immediately?

If your pet passes large amounts of fresh blood or tarry black stools, experiences continuous heavy incontinence with dehydration, or suddenly cannot move normally or stand, seek emergency care immediately to avoid delay. Contact your vet or an emergency clinic right away.

How should I follow up and schedule check-ups after treatment?

Depending on the diagnostic findings, dietary adjustments, medication changes, or further tests may be needed. Always attend follow-up appointments as directed to monitor symptoms, body weight, and repeat fecal or imaging checks. If symptoms do not improve, consult your vet.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

01What symptoms indicate a problem?

Fecal incontinence means your pet cannot control their bowel movements, often accompanied by abnormal stool, discomfort during defecation, or behavior changes. Watch for signs that persist or worsen.

Involuntary leakage of stool, soiling bedding, sleeping mats, or the floor
Blood in stool or dark, tarry (melena-like) feces
Signs of pain or crying out during defecation
Tenesmus (straining) or a sensation of incomplete defecation
Reduced appetite or noticeably decreased activity levels
Persistent or recurring symptoms warrant a veterinary consultation

Seek emergency care immediately if you notice the following symptoms:

⚠️ Continuous heavy stool leakage accompanied by dehydration or lethargy
⚠️ Large amounts of fresh blood in the stool or black tarry stools
⚠️ Severe abdominal pain or sudden inability to move normally or stand

02How to assess symptoms at home: key observations and when to seek emergency care

Observing and recording details at home helps your vet quickly assess the condition and identify possible causes.

Record the onset time, frequency of bowel movements, and pattern of episodes
Use your phone to film defecation or abnormal behavior for reference
Weigh your pet daily or weekly and track any weight trends
Monitor changes in appetite, water intake, and overall energy levels
Collect a fresh stool sample, refrigerate it, and bring it to the clinic
If symptoms persist or worsen, schedule a vet appointment as soon as possible

03How will the vet diagnose this? Common diagnostic tests

The vet will arrange a physical exam and necessary tests based on the medical history and clinical signs, to determine whether the problem is local or systemic.

Physical examination and digital rectal palpation to assess the anal and rectal region

X-rays to evaluate pelvic structure, intestinal positioning, and signs of obstruction

Abdominal ultrasound to examine the intestinal wall, organs, and surrounding tissues

Fecal examination, culture, or PCR testing to detect infectious agents

Cytology, biopsy, or blood work when further investigation is needed

04What treatment and care are needed after diagnosis? Medications, dietary adjustments, and care guide

Treatment is determined by diagnostic findings; home care and regular follow-up visits improve outcomes and monitor recovery.

Develop a medication, dietary, or surgical plan based on diagnostic results
Follow the vet's dietary recommendations to adjust food type and feeding method to improve bowel habits
Maintain cleanliness at home and support scheduled toileting routines and hygiene care
Attend regular follow-up appointments to monitor symptoms, body weight, and test results
Schedule repeat fecal or imaging checks on time to evaluate treatment response and make adjustments

05What to prepare before the vet visit: key information to help your vet identify the cause quickly

Note when symptoms began, how often they occur, and how they have progressed

List daily bowel movement frequency, stool color, and any changes in consistency

Note any recent dietary changes, treats given, and known allergies

Bring a fresh stool sample and a list of current medications

Take videos or photos of the symptoms to share with your vet

Bring any previous lab reports or imaging results to the appointment

Book an appointment in advance at a clinic with imaging capabilities
