How to Help a Dog That’s Constipated at Home

Recognize the Signs of Constipation

A dog with constipation may strain to defecate without success, pass hard and dry stools, or go more than 48 hours without a bowel movement. Straining can also occur with other issues like colitis, bladder obstruction, or anorectal blockages, so it's important to rule out these conditions. Signs like passing mucus or blood, crying during defecation, or a foul smell around the rear may indicate a more serious problem.

Common Causes of Constipation

Constipation often results from dehydration, low-fiber diets, or ingesting foreign materials like bone chips, hair, grass, or cloth. Older dogs and those with reduced activity are especially prone. Some dogs withhold stool during housetraining or when left alone, and others may avoid defecating when stressed, such as during travel or hospitalization. Underlying medical issues like hypothyroidism or an enlarged prostate in male dogs can also contribute.

Safe Home Remedies to Try

Start by ensuring your dog has constant access to clean, fresh water. Soak dry kibble in equal parts water for 20 minutes to increase moisture. Add fiber to the diet: one teaspoon of ground flax seed per cup of food, one-half teaspoon of Metamucil per ten pounds of body weight daily, or one tablespoon of canned pumpkin twice a day. Regular exercise helps stimulate bowel movements—take your dog outside several times a day, especially to familiar spots.

When to Seek Veterinary Help

Contact your vet if your dog hasn’t had a bowel movement in several days, is in pain, or shows signs of obstruction like vomiting, loss of appetite, or a swollen belly. If your dog is straining but passing only small amounts of stool with mucus or blood, it may be colitis, not constipation. Enemas meant for humans are dangerous—only use products recommended by your vet. In severe cases, a vet may need to manually remove an impaction or provide fluid therapy.

Prevention Tips for the Future

Prevent future episodes by feeding a high-fiber diet, such as Hill’s Prescription w/d or senior dog food. Avoid giving bones, rawhide, or other non-food items. Keep your dog’s coat clean and free of mats, especially around the rear, to prevent mechanical blockage. Regular grooming and consistent bathroom breaks help maintain healthy bowel habits.
