How Long Can A Dog Go Without Pooping? | Reasons & Solution

Have you noticed your dog not pooping? Skipping a day can happen, but a dog that goes several days without a bowel movement may have a health problem that needs a vet.

The question is, how long can a dog go without pooping before it becomes troubling? Most healthy dogs poop at least once a day. If your dog hasn't pooped in 48 hours, or keeps straining without passing stool, call your vet. Go right away if your dog is also vomiting, not eating, lethargic, or has a painful or swollen belly.

You should keep an eye on your dog’s pooping behavior because changes in bowel movements can point to a health issue. There are several reasons your dog may be skipping poops, so talk to your vet before it becomes a big deal.

Is It Normal For a Dog to Not Poop For a Day?

Missing a day once in a while isn't usually an emergency, especially if your dog is eating, drinking and acting normally. Watch your dog closely and call your vet if it goes 48 hours without pooping.

Travel, stress, a change in routine or diet, eating less than usual, or not finding a spot it likes can all cause a dog to skip a day.

If skipped days keep happening, something may be wrong, so ask your vet to look for the cause.

What Are the Reasons My Dog Not Pooping?

Reasons My Dog Not Pooping

Here are a few reasons your dog might not poop and what you should do about them.

1. Constipation

A constipated dog passes small, hard, dry stools or strains without passing anything. Owners sometimes ask about over-the-counter laxatives such as MiraLAX. Only give a human laxative if your vet tells you to, and use the dose your vet gives you for your dog.

Fresh water and enough fiber also help prevent constipation. A dog that doesn't drink enough can become dehydrated, which makes stools hard and dry.

2. Diarrhea

Straining can also be a sign of diarrhea or an inflamed colon, not constipation. A dog with an irritated colon may squat and strain often but pass little or only liquid stool.

Watch your dog when it goes outside to see what it passes. Since the two problems need different care, ask your vet before you treat either one. You can read more about diarrhea in our guide.

3. Foreign Object or Obstruction

Your dog may have a blockage if it has eaten something it can't digest, such as sticks, rocks, socks, toys or bones. These objects can get stuck in the dog’s digestive tract and stop anything from passing.

A blocked dog may also vomit, stop eating and have belly pain. A blockage is an emergency, so take your dog to the vet right away.

4. Painkillers

Some medicines can cause constipation in dogs. The Merck Veterinary Manual lists opioids, diuretics, antihistamines and several other drugs among the medications that can promote constipation.

If your dog becomes constipated on a pain medicine such as tramadol, call your vet. Don't stop or reduce a prescribed medicine on your own.

5. Not Eating

A dog that isn't eating will poop less, because less food is going in. This is common in dogs that are ill.

Not eating is a problem of its own, though. If your dog skips meals for more than a day, call your vet.

6. Tumors

Tumors in or around the rectum or anus can block the passage of stool. Your vet will decide on treatment, which may include surgery.

Many dogs also don't poop for a day or two after surgery of any kind. This can happen because:

They eat less before and after surgery.
Pain or pain medicine makes passing stool harder.
They may be fed a highly digestible diet that produces less stool.
They were fasted before the operation.

Ask your vet how long is normal after your dog's surgery and when to call.

7. Over-Matted Fur

Matted fur around the anus can trap stool and make it hard for a dog to poop. Keep the area trimmed and clean. A groomer or vet can safely clip badly matted fur.

8. Eating insufficient or Excessive Fiber

A low-fiber diet can lead to constipation. Too much fiber, especially without enough water, can also cause problems. A complete and balanced dog food is the best base, and your vet can tell you if your dog needs extra fiber.

9. Swollen Anal Glands

A dog with swollen or impacted anal glands may find it painful to poop. Have your vet check the glands if your dog scoots, licks the area, or strains. Don't try to express them yourself unless your vet has shown you how.

What To Do That Makes My Dog Poop

If your dog is pooping less than usual but is otherwise bright and eating, these simple steps may help. If they don't help within a day or two, call your vet.

Exercise Routine

Take your dog for a walk every day, ideally after meals. Movement helps the gut work. When your dog poops outside, praise it or give a treat so it learns what you expect.

Increase Water Intake

Make sure your dog always has clean, fresh water. A dog that doesn't drink enough can become constipated.

Increase Fiber

Fiber helps keep stools soft and regular. Plain canned pumpkin (not pie filling, which has sugar and spices) is a common fiber source for dogs. Ask your vet how much to give, and don't add fiber supplements made for people without your vet's advice.

Stimulates Dog Bowl Movement

Gently massaging your dog's belly and keeping it active can help. Don't put anything into your dog's rectum or try home enemas; the Merck Veterinary Manual notes that more severe cases may need enemas or removal of stool by a vet.

Take a Look What Your Dog Eat

If your dog is hardly pooping, look at its diet and recent habits. Constipation can be caused by diet, medicines, too little exercise, or something your dog swallowed.

Ask your vet whether your dog needs more fiber or a different food. If things don't improve, have your dog examined.

OTCs Medications

Don't give your dog any over-the-counter or human medicine, including laxatives such as MiraLAX, unless your vet tells you to.

A laxative can make an obstruction worse and can cause dehydration. Your vet needs to rule out a blockage first and will give you a safe dose for your dog's size and health.

What are the Signs of Constipation?

The symptoms of constipation are:

Difficulty passing stools
Whining or crying while pooping
Vomiting
Passing small, dry, hard feces
Straining to poop
Other signs of pain
Reduced appetite
Lethargy

If you notice these signs, call your vet. Your vet will check whether your dog is constipated or has another problem.

What are the Causes and Treatments for Constipation?

Some common causes of constipation are:

An enlarged prostate
A mass in the large intestine or rectum
A perineal hernia
Dehydration
Kidney disease
Swallowed objects or bone fragments
A low-fiber diet
Side effects of medications
Poor appetite and not eating

The Merck Veterinary Manual's chapter on constipation says mild constipation can often be treated by avoiding dietary indiscretion, making sure the dog has access to water, and feeding a high-fiber diet. Your vet may suggest:

A higher-fiber diet or plain canned pumpkin.
More regular exercise.
A laxative or stool softener chosen and dosed by your vet.
A prescription diet.
Enemas or removal of impacted stool at the clinic for severe cases.

When do I Visit my Vet if my Dog is not Pooping?

Call your vet if your dog hasn't pooped in 48 hours, or sooner if it strains repeatedly without passing stool. Go right away if your dog is vomiting, not eating, lethargic, or has a swollen or painful belly, because these can be signs of a blockage.

What will the Vet do if my Dog is not Pooping?

Your vet will start with a physical exam, which usually includes a rectal exam to feel for hard stool, masses or narrowing.

X-rays (radiographs) show how much stool is in the colon and can reveal bones or other objects. Blood tests may look for underlying causes.

If your dog is constipated, your vet may give an enema or remove the stool under sedation. Never give your dog an enema at home; some human enema products are toxic to pets.

How to Promote Digestion Health in my Dog?

Feed a complete and balanced diet.
If your dog is prone to constipation, ask your vet about a higher-fiber food.
Keep your dog well hydrated with fresh water at all times.
Take your dog to the vet for regular checkups.
