Noticing that your dog isn’t having regular bowel movements can be concerning. Constipation or infrequent stools may indicate underlying digestive issues, dehydration, or other health problems that require attention.
Dogs of all ages may occasionally skip a day, but consistent difficulty or refusal to pass stool can point to medical conditions or dietary concerns.
We outline the common reasons why a dog may not have a bowel movement, what you can do at home, and when to seek veterinary help.

Dog Not Having Bowel Movement: Why It Happens
A dog not having a bowel movement is usually caused by constipation, digestive blockages, dehydration, or underlying medical conditions. In some cases, dietary changes, ingestion of foreign objects, or medications can also contribute to infrequent stools.
Behavioral factors such as stress or changes in routine can temporarily suppress bowel activity.
Dog Not Having Bowel Movement: Common Causes
Constipation Due to Dehydration
Dehydration is a common contributor to constipation in dogs. When a dog does not drink enough water, the stool becomes hard and difficult to pass, resulting in infrequent bowel movements.
Signs include dry gums, lethargy, and infrequent urination. Chronic dehydration can lead to discomfort, abdominal pain, and potential complications like fecal impaction.
Ensuring your dog has access to clean, fresh water and encouraging regular drinking is essential for maintaining normal bowel function.

Dietary Issues
A diet low in fiber or sudden changes in food type can cause a dog to become constipated.
Dogs need sufficient fiber to promote regular bowel movements, and a lack of it can result in hard, dry stools.
Overfeeding table scraps or consuming indigestible materials can also disrupt normal digestion.
You may notice straining, smaller stools, or prolonged intervals between bowel movements. Adjusting the diet to include high-quality fiber sources and gradually introducing changes can help restore normal bowel activity.
Ingestion of Foreign Objects
Dogs, especially puppies, may swallow non-food items such as toys, bones, or fabric. These objects can obstruct the intestines, preventing stool from passing.
Signs of a blockage include straining without producing stool, vomiting, abdominal pain, and lethargy.
Gastrointestinal blockages can become life-threatening if not treated promptly, requiring veterinary evaluation and sometimes surgical intervention to remove the obstruction.
Anal Gland Problems
Impacted or infected anal glands can make defecation uncomfortable or painful for a dog. Dogs may avoid bowel movements to prevent discomfort, leading to constipation.
You might notice scooting, licking the anal area excessively, or unusual odor.
Treating anal gland issues through veterinary care, expression, or dietary adjustments helps restore normal bowel function and comfort.
Medication Side Effects
Certain medications, such as opioids, antihistamines, or antacids, can slow intestinal motility, leading to constipation.
Dogs taking long-term medications may develop infrequent stools or difficulty passing bowel movements.
You should monitor you dog closely and consult your veterinarian for alternative medications, dosage adjustments, or supportive measures such as fiber supplementation or stool softeners.
Chronic Health Conditions
Underlying medical conditions like hypothyroidism, kidney disease, or neurological disorders can interfere with bowel movements.
Dogs with these conditions may experience slower digestion, reduced gut motility, or abdominal discomfort, making it difficult to pass stool.
Observing additional symptoms such as lethargy, weight changes, or abnormal urination can help identify the underlying problem.
Timely veterinary diagnosis is crucial to manage chronic conditions and maintain healthy bowel function.

What to Do If Your Dog Is Not Having Bowel Movement
Monitor your dog closely and ensure they have access to fresh water at all times. Gentle exercise, such as short walks, can stimulate bowel movement and promote healthy digestion.
Providing a diet rich in fiber, or temporarily adding a small amount of canned pumpkin or specialized fiber supplements, may help soften stool and encourage regular bowel movements.
Avoid forcing your dog to defecate, as this can increase stress and discomfort. Maintaining a consistent feeding schedule and observing for other concerning signs can guide whether further intervention is needed.
When to Call or Visit Your Vet
Contact your veterinarian if your dog hasn’t had a bowel movement for more than 48 hours, or if there are accompanying signs such as vomiting, lethargy, straining, abdominal bloating, or loss of appetite.
Persistent constipation or suspected obstruction can lead to serious complications like fecal impaction or gastrointestinal distress.
Your veterinarian may recommend physical examination, abdominal imaging, or blood tests to determine the cause and appropriate treatment.
Prompt intervention ensures your dog remains comfortable and prevents potential emergencies.
