Dog Constipation: Causes, Symptoms and Natural Remedies for Irish Dog Owners

Constipation is a common but often overlooked health issue in dogs. While most cases resolve on their own or with simple dietary adjustments, chronic or severe constipation can become a serious health problem. Understanding the causes and knowing when to seek veterinary help is important for every dog owner.

Signs of Constipation in Dogs

Normal bowel habits vary between dogs, but as a general rule, most adult dogs defecate 1–2 times per day. Signs that your dog may be constipated include:

• No bowel movement in 24–48+ hours
• Straining or squatting repeatedly without producing stool
• Producing only small, hard, dry stools
• Crying or showing signs of discomfort when trying to defecate
• Lethargy
• Loss of appetite
• Vomiting (in more severe cases)
• Bloated or distended abdomen

Important: Straining can also be a symptom of diarrhoea (tenesmus) or urinary issues. If you're unsure whether your dog is constipated or has another problem, contact your vet.

Common Causes of Constipation in Dogs

• Insufficient dietary fibre: Low-fibre diets don't provide enough bulk to keep stools moving through the intestines efficiently.
• Dehydration: Inadequate water intake causes the colon to absorb more water from stools, making them hard and difficult to pass.
• Inactivity: Exercise stimulates intestinal movement. Sedentary dogs are more prone to constipation.
• Ingesting foreign material: Bones, grass, hair, or other non-food items can cause blockages or hard stools. Bone fragments are a particularly common cause.
• Anal gland problems: Painful or impacted anal glands can make defecation uncomfortable, causing dogs to hold in stool.
• Medications: Some medications (particularly antihistamines, diuretics, and some pain medications) can cause constipation.
• Enlarged prostate: In unneutered male dogs, an enlarged prostate can press on the colon.
• Anxiety or change in routine: Some dogs become reluctant to defecate in unfamiliar places or during stressful periods.
• Neurological issues: Nerve damage can interfere with normal bowel function.

When to See a Vet

Contact your vet if your dog:

• Has not had a bowel movement in more than 48 hours
• Is in obvious pain or distress
• Is vomiting alongside constipation
• Has a distended abdomen
• Has blood in the stool
• Is a puppy, senior, or has a known health condition
• You suspect they've swallowed something (toys, clothing, bones)

Natural Remedies and Dietary Solutions

For mild, occasional constipation in otherwise healthy adult dogs, dietary measures can often resolve the issue:

1. Increase Water Intake

Ensure fresh water is always available. Adding water or unsalted broth to food can help increase fluid intake. Wet food naturally contains much more moisture than dry kibble and can help dogs that struggle to drink enough.

2. Add Fibre to the Diet

• Pumpkin pureé (plain, not spiced pie filling): 1–4 tablespoons per day depending on dog size. Pumpkin is rich in soluble fibre that adds bulk and draws water into the colon.
• Canned, plain green beans: Low in calories and high in fibre — can be added to meals.
• Cooked sweet potato: Good source of soluble and insoluble fibre.
• Raw carrots: Crunchy, high in fibre, and most dogs enjoy them.

3. Increase Exercise

Even a short walk can stimulate bowel movement. If your dog is constipated, try an extra walk or longer exercise session to get things moving.

4. Review the Diet

If constipation is recurring, evaluate your dog's regular diet. A high-quality, nutritionally complete diet with appropriate fibre levels is the foundation of good digestive health. Our grain-free dog food range uses natural, high-quality ingredients that support healthy digestion. For dogs with chronic digestive issues, our sensitive stomach range may provide the right balance of fibre and digestibility.

5. Avoid Giving Bones

Cooked bones, in particular, are a major cause of constipation in dogs. Bone fragments form hard, chalk-like stools that can be painful or impossible to pass. Remove cooked bones from your dog's diet.

What Not to Do

• Do not give human laxatives without vet advice. Many are toxic to dogs.
• Do not give mineral oil orally — it can be accidentally inhaled and cause aspiration pneumonia.
• Do not wait more than 48 hours to seek veterinary advice if home remedies aren't working.

Preventing Constipation Long-Term

• Feed a complete, balanced diet with appropriate fibre content
• Ensure constant access to fresh water
• Maintain regular exercise
• Keep your dog at a healthy weight
• Groom regularly to reduce hair ingestion (especially in long-haired breeds)
• Have anal glands checked regularly by your vet or groomer

Frequently Asked Questions

How long can a dog go without pooping?

Most healthy adult dogs should defecate at least once every 24–48 hours. Going more than 48 hours without a bowel movement is concerning and warrants a call to your vet.

Is pumpkin good for constipated dogs?

Yes — plain pumpkin pureé (not pie filling with spices) is an excellent natural remedy for mild constipation. The soluble fibre draws water into the stool, softening it. Start with 1 teaspoon for small dogs, up to 4 tablespoons for large dogs, mixed into food.

Can I give my dog olive oil for constipation?

A small amount of olive oil (1 teaspoon for small dogs, 1 tablespoon for large dogs) mixed into food can help lubricate the digestive tract and ease mild constipation. Use sparingly and not as a regular practice — high fat intake can trigger other digestive problems.

Why does my dog seem to strain but nothing comes out?

This could be constipation, but it can also indicate a urinary problem (especially in male dogs), anal gland discomfort, or diarrhoea. If you can't clearly identify what's happening, contact your vet to rule out more serious causes.

Can certain dog foods cause constipation?

Yes. Low-fibre, highly processed diets can contribute to constipation. Foods high in bone meal or calcium can also cause very hard, chalky stools. A high-quality, complete dog food with appropriate fibre from natural sources supports better digestive regularity.
