If there’s one thing most dog owners would agree on, it’s that constipation is uncomfortable — for everyone involved. And while your dog can’t tell you how they’re feeling, their behaviour often says it all: repeated squatting, straining with little or no result, or seeming uncomfortable on walks.
Constipation in dogs is more common than many pet parents realise. The good news? In many cases, it’s temporary and manageable once you understand what’s going on and how to support your dog’s digestive health.
Here’s what you need to know — from common causes and warning signs to gentle ways to help get things moving again.
What Causes Constipation in Dogs?
Just like humans, dogs can experience constipation for a variety of reasons, ranging from mild lifestyle factors to more serious health concerns. Understanding the cause is key to choosing the right solution.
Diet & Fibre Intake
One of the most common contributors to constipation is a lack of dietary fibre. Some highly processed dog foods and treats don’t provide enough insoluble fibre to support healthy bowel movements.
Sudden diet changes can also temporarily disrupt digestion. Even switching to a higher-quality or more fibre-rich food may cause short-term constipation while your dog’s gut adjusts.
Ingesting Non-Food Items
Dogs explore the world with their mouths, which means they sometimes swallow things they shouldn’t. Items like toy stuffing, fabric, plastic, kitty litter, or even bones can cause partial or complete intestinal blockages.
If constipation comes on suddenly and your dog has a history of chewing or scavenging, this is something to take seriously.
Age-Related Changes
As dogs age, their digestive systems can naturally slow down. Older dogs may also be less active, which can contribute to sluggish bowel movements — even if they’ve never had issues before.
Lifestyle & Activity Levels
Movement plays a big role in digestion. Dogs that don’t get enough daily exercise may struggle to stimulate regular bowel movements. A more sedentary lifestyle, whether due to routine changes or owner availability, can quickly impact gut health.
Medications
Certain medications — including some pain relief drugs and antibiotics — are known to cause temporary constipation. If your dog has recently started a new medication, this may be a contributing factor.
Illness, Stress & Emotional Factors
Physical illness that limits mobility or affects appetite can slow digestion. But emotional stress matters too. Anxiety, fear, trauma or separation stress can all trigger a “fight or flight” response that temporarily shuts down normal bowel function.
Underlying Disease
In some cases, constipation may be a symptom of a more serious condition. This can include hormonal imbalances (such as hypothyroidism), spinal or neurological issues, tumours, joint disease, or metabolic disorders. Persistent or recurring constipation should always be investigated by a veterinarian.
Constipation vs Obstipation: What’s the Difference?
Constipation
Constipation is typically a short-term or acute issue where a dog struggles to pass stool but may still produce small, hard bowel movements.
Most dogs have one to two bowel movements per day. If this suddenly changes and your dog hasn’t gone for a day or two, constipation may be the cause.
With gentle intervention — and sometimes veterinary guidance — temporary constipation usually resolves within a couple of days.
Obstipation
Obstipation is a far more serious condition. It occurs when stool becomes extremely hard and impacted, making it impossible for your dog to pass at all.
As stool sits in the colon, moisture continues to be absorbed, making it harder and drier over time. Without intervention, obstipation can become life-threatening and may require surgery.
If your dog hasn’t passed stool for several days and seems uncomfortable, lethargic or unwell, seek veterinary care immediately.
How to Help a Constipated Dog at Home
If your dog is otherwise well and constipation appears mild, there are several vet-approved steps you can take at home to support digestion.
1. Increase Moisture in the Diet
Hydration is essential for healthy digestion. Adding moisture can often help soften stool and encourage movement.
-
Add plain pumpkin purée (no sugar or spices) to meals
-
Mix in warm water or bone broth to create a soup-like consistency
-
Consider temporarily feeding a high-quality wet food
Pumpkin is particularly popular because it’s high in both fibre and moisture — and most dogs love the taste.
2. Support Fibre Intake
Some dogs benefit from extra dietary fibre to help regulate bowel movements.
Options may include:
-
Psyllium husk (vet-approved amounts only)
-
Bran or natural fibre supplements
-
Small amounts of healthy oils to lubricate the digestive tract
Always check with your veterinarian before adding oils or supplements, especially if your dog has weight, dietary or medical considerations.
3. Encourage Hydration
If your dog isn’t drinking enough water, try:
-
Adding broth to meals
-
Offering fresh water in multiple locations
-
Using pet fountains to encourage drinking
Dehydration can worsen constipation quickly, so hydration is key.
4. Gentle Exercise
Movement stimulates digestion. Even a short walk can help encourage a bowel movement.
That said, dogs recovering from surgery, illness or joint issues may need alternative approaches — always prioritise safety and comfort.
When to See the Vet
You should contact your veterinarian if:
-
Your dog hasn’t had a bowel movement in more than 48 hours
-
Home remedies haven’t helped
-
Constipation keeps recurring
In some cases, your vet may recommend additional at-home steps. In others, they may want to examine your dog to rule out blockages or underlying conditions.
Warning Signs That Need Immediate Attention
Seek veterinary care urgently if your dog shows any of the following:
-
Blood where stool should be
-
Bloating or a swollen abdomen
-
Vomiting, especially if ongoing
-
Pain, crying or severe straining when trying to pass stool
These symptoms can indicate serious issues beyond simple constipation.
Supporting Digestive Health Long-Term
The best way to manage constipation is prevention. Feeding a high-quality, nutrient-dense diet, ensuring regular exercise, supporting hydration, and maintaining a consistent routine all play a role in long-term digestive health.
And when things do get moving again? Being prepared makes life easier. Using plant-based, responsibly made poop bags helps you clean up safely while being kinder to the environment.
