Dog Constipation: Causes, Symptoms and Natural Remedies

Dog constipation is more common than many owners realise — and it can be uncomfortable and distressing for your pet. If your dog is straining to go to the toilet, passing very small or hard stools, or hasn't had a bowel movement in a day or two, constipation is likely the cause. The good news is that mild cases can often be resolved with simple dietary and lifestyle changes, and understanding what's behind the problem helps you prevent it from recurring.

What Is Dog Constipation?

Constipation in dogs refers to infrequent, difficult or absent bowel movements, often accompanied by dry, hard faeces. Most healthy dogs pass stools once or twice a day. If your dog goes more than 48 hours without defecating, or is clearly straining without producing a normal stool, it's worth paying attention. Occasional constipation is normal and usually resolves quickly, but chronic or severe constipation can lead to a condition called obstipation — where the colon becomes so impacted that the dog is completely unable to pass stool without veterinary intervention.

Constipation is different from diarrhoea but both reflect digestive imbalance, often linked to diet. Maintaining consistent digestive health is one of the key reasons that what you feed your dog matters so much day to day.

Common Causes of Constipation in Dogs

There are several reasons why a dog might become constipated. The most common include insufficient dietary fibre, which slows gut transit time; dehydration, which causes the colon to absorb more water from the stool making it hard and dry; and lack of exercise, which affects gut motility. Dogs that groom themselves excessively or eat grass, hair or other non-food material can develop blockages that contribute to constipation.

In older male dogs, an enlarged prostate can compress the rectum and make defecation difficult. Certain medications — including antihistamines, diuretics and some pain medications — can also cause constipation as a side effect. Underlying health conditions such as hypothyroidism, spinal problems or neurological issues may affect the nerves that control bowel function. If your dog is repeatedly constipated without an obvious dietary explanation, a vet check is warranted to rule out these causes.

Symptoms of Constipation to Watch For

The clearest sign of constipation is a dog squatting and straining repeatedly with little or no result. Other symptoms include passing very small, dry, pebble-like stools; crying or whimpering when attempting to defecate; a hunched posture or obvious discomfort; decreased appetite; and in some cases, vomiting. Some constipated dogs will circle repeatedly before squatting, or drag their bottom along the ground — though this can also indicate anal gland issues, which your vet can assess.

Natural Remedies for Dog Constipation

For mild constipation, several natural approaches can help get things moving again. Increasing your dog's water intake is the first step — try adding a little warm water or low-salt broth to their food to encourage hydration. Adding dietary fibre is often very effective: plain cooked pumpkin puree (not pie filling) is a popular and gentle remedy, as are cooked green beans or grated raw carrot. Our article on whether dogs can eat carrots has more detail on safely adding this fibre-rich vegetable to your dog's diet.

Increasing exercise can also stimulate bowel activity — a longer walk or some gentle play often helps. Probiotics are another useful tool: a healthy gut microbiome supports regular, healthy digestion. Read more about probiotic benefits in our guide on probiotics for dogs.

How Diet Prevents Dog Constipation

Diet is the single biggest factor in your dog's digestive regularity. A high-quality diet that contains the right balance of protein, fat and fibre — and is free from low-quality fillers — supports healthy, consistent gut function. Grain-heavy, low-quality foods can disrupt digestion and contribute to both constipation and digestive irregularity over time.

When to See Your Vet

Mild, occasional constipation that resolves within a day or two with dietary adjustments usually isn't cause for alarm. However, if your dog hasn't passed stool in more than 48–72 hours, is in evident pain, is vomiting or bloated alongside constipation, or if constipation is a recurring pattern, please contact your vet. A vet can safely relieve the impaction if needed and investigate any underlying causes to prevent the problem from returning.
