Why Does My Dog Poop So Much At Night: Top 5 Reasons in [year]

Why does my dog poop so much at night? This is a common question among dog owners and sitters.

Assuming you have already consulted a vet and your dog is well-trained, there are several other reasons other than medical and lack of training that can cause a dog to poop or have accidents at night.

In this article, we shall go further and explain how these factors contribute to dog pooping at night and how to overcome them.

Why Does My Dog Poop So Much At Night? Major Reasons

There are several reasons why your dog poops so much at night. It could be a sign of excessive feeding, having a bedtime right after their meal, a high-protein rich diet, a high-fiber diet, or due to prevalent stress and anxiety in the canine. If this becomes a habit, we’d recommend consulting a vet near you to immediately understand what’s wrong and what you can do to fix the issue.

Let’s discuss this in detail:-

1. Overfeeding The Dog

Overfeeding your dog could be one of the reasons why he or she poops so much at night.

Most vets recommend at least 2 meals a day based on your dog’s weight. Each portion should be just enough to fill the dog’s stomach and no more.

Measuring the amount of food the dog eats is a good idea. But bearing in mind that some dry dog foods expand when wet, it is important you soak food in equal amounts of water before feeding.

For instance, put one cup of water in one cup of dry food. If the food swells a great deal, reduce it to the usual amount your dog eats. This will help prevent overfeeding as well as minimize the amount of water intake. Thus, fewer poops and urine and he or she may not need to go at night.

2. Bedtime Immediately After A Meal

Most vets argue that dogs tend to have a bowel movement about 15-30 minutes after a meal. So when you feed them just before bedtime, there is a high possibility that they will defecate in the house.

The best thing to do is to take him or her for a walk 20 minutes after a meal or play with him in the yard for a while. This will help in digestion and stimulate bowel movement.

If he takes a poop while outside, praise him for it and even reward him with a treat. It will encourage him to always look forward to going outside with you so that he can poop and be rewarded.

3. Food Heavy in Protein

Dogs love meat, right? So why not feed them on food rich in protein?

Well, the answer is quite simple. Dogs do not feed on meat only like wolves, their close relatives, do.

They have evolved over the years to a point where their digestion system can comfortably digest plant-based starches, vitamins, and other minerals. For this reason, dogs need a variety of nutrients for proper nutrition.

Feeding them excess protein means that only a certain percentage will be absorbed into their body while the rest will be excreted. This translates to more poop whether in daytime or at night. Worse still, the protein that is not absorbed ferments, which makes your dog’s waste stink even more.

However, you should also take care not to feed your dog too little protein. This is because they need protein for energy, to build strong muscles, and to repair broken tissues. It is, therefore, recommended that dry food for an adult dog should contain about 22% of crude protein while a puppy should consume not less than 22.5%.

Always consult your vet on the recommended amount of nutrients that your dog should take based on its age and level of activity.

4. A Low Quality Diet That is High in Fiber

Another reason could be your dog is taking low-quality diet food with insignificant nutritional density and high fiber

Most pet owners tend to go for lower cost pet foods oblivious of the fact that they have a higher proportion of wheat and corn compared to the higher cost pet foods. Consuming a lot of corn and wheat foods means more fiber in the dog’s stomach, which increases the volume of stool. Hence, the need to go often even at night.

The solution is, therefore, to change to a higher quality diet so that the dog can feed less often and poop fewer times.

5. Anxiety and Stress

Did you recently change your dog’s routine? Was he used to sleeping next to your bed and now he has to sleep in his own room?

These are some of the reasons why your dog could be experiencing stress and anxiety. Aging, as well as fear of loud noises and animals, are also major contributors to dog anxiety.

As a result, some dogs may suffer from stress-related diarrhea. Pooping and urinating in the house are ways that you can determine whether or not your dog is suffering from anxiety or stress.

If anxiety and stress are left untreated, they can lead to behavioral changes or other issues that may be difficult to deal with. The solution is to seek help from the vet to help you determine the type of anxiety your dog is suffering from and the possible triggers. The vet may administer anti-anxiety medications to help your dog recover from the anxiety.

Detailed Explanations – Why Does My Dog Poop So Much at Night?

1. Dietary Issues 

You’ll probably notice your dog pooping more if you abruptly modify their food. When you entirely alter what your dog is eating in their bowl, it may take some time for their intestines to adjust since their stomach grows acclimated to particular foods.

Dietary Issues - Why Does My Dog Poop So Much at Night?

They will start to recover in two weeks at the most, but you may prevent this by carefully transitioning them to a new food. Instead of just transferring from one food to the other, combine the foods, beginning on day one with 80% of their current diet and 20% of their new food.

Adjust the proportion of old to fresh food over roughly a week until they follow the latest diet entirely after around seven days.

You must use caution while deciding which meals to give your dog. An improper sort of diet can be harmful to their general health as well as cause strange bowel motions.

An excellent place to start is by selecting foods of high quality that are rich in new meat-based proteins, moderate in healthy fats, and low in carbs.

One of the warning signals that the food you’ve chosen doesn’t have the correct balance of nutrients for your dog is excessive bowel movements.

While it could be a high-quality food, this may not contain the correct proportion for your dog, particularly if they have deficiencies or are sensitive to specific ingredients.

Speak to your veterinarian about any potential unique dietary requirements your dog may have if it continues to defecate a lot when eating a reputable brand of dog food. Your dog’s diet can affect their pooping behavior due to the following reasons too:

2. Health-Related Issues 

As a pet parent, it is never easy to read about health concerns that may be affecting your pet’s daily behavior. However, it is essential for you to remember that most health-related issues are treatable.

Health-Related Issues 

If detected early, they can be treated, and your pet can live a comfortable and healthy life. Remember, nothing matters more than your pet’s health!

Several dog experts suggest that if you detect an unusual change in your pet’s eating habits, you need to look for signs like dietary changes, monitor their eating habits, and eliminate any unhealthy eating cycles.

You can look for alterations in the consistency of their poop and the change in timings of their pooping ritual.

If you come across any such alterations, you need to check for any health concerns that may be affecting your furbabies. 

1. Orthopedic Conditions 

You might be surprised that an orthopedic ailment might bring your pet’s nighttime feces. You may be asking how that is even feasible.

Actually, it’s relatively easy. Your dog may have arthritis, making the dumping position uncomfortable for them. The stiffness or swelling of limbs brought on by arthritis might limit your pet’s movement.

I’m aware of your thoughts at this point. Why is it that your furbaby doesn’t experience discomfort when going to the bathroom at night if arthritis is the cause of your pet’s late-night pooping?

A poopy surprise might also be waiting for you when you awaken in the morning beside the entrance, in the hall, or somewhere else in your house. If so, it is probably there just because your dog prefers to relieve himself in that location.

Additionally, you can identify the symptoms of arthritis in your dog by keeping an eye out for the following signs:

  • Unusual gait
  • Awkward movements upward
  • Lethargy
  • Stiffness
  • Refusal to move about a lot

2. Gastrointestinal Problems

The late-night dog pooping problem can also be due to gastrointestinal issues. Your pet’s nutrition can significantly impact irregular bowel movements, in addition to the fact that some dog breeds (such as pugs or retrievers) have sensitive bellies.

If you give your dog inexpensive dog food, it can desire to urinate more frequently. A recognized brand of dog food, on the other hand, will not only lead to reduced waste evacuation but may also help your furry friend feel fuller for longer.

This is our top pick if you’re seeking new dog food that will support a healthy digestive system for your little furry friend.

3. Physical Issues 

Just like humans, dogs can get IBS or inflammatory bowel disease. They may find it challenging to regulate when they defecate as a result.

Additionally, it could make them feel rushed, which might result in mishaps. Other painful illnesses like arthritis may also be at blame. Going outside might not be worth the hassle if it hurts your dog to move.

Alzheimer’s disease can also afflict dogs. Just as in people, this results in cognitive deterioration and amnesia in dogs.

The dog can forget how to use the bathroom or perhaps be unaware that they are inside. Your dog may defecate inside the home due to liver illness, cancer, diabetes, or kidney stones.

A dog will typically have problems during the day if it has physical issues that cause it to poop at night. 

4. Irritable Bowel Syndrome (IBS)

Dogs with irritable bowel syndrome (IBS) have stomach or intestinal distress due to inflammation in the gut lining. It generally lasts a night and might cause symptoms, including nausea, stomach distress, or diarrhea.

Even though the actual source of IBS in dogs isn’t always understood, there are a number of things that might have an impact, such as food, allergies, intestinal blockage, and stress.

IBS symptoms in dogs often relate to the digestive tract. Although these signs might come and go, they commonly and persistently manifest.

You should visit your veterinarian for care and prognosis because several IBS symptoms, such as diarrhea, and nausea, are frequent problems that also occur with other illnesses and conditions.

The following are some typical canine IBS signs:

  • Chronic diarrhea
  • Feces with mucus
  • Vomiting and nauseous
  • Lethargy or depression
  • Discomfort when belly-lying
  • Appetite loss and weight loss
  • Abdominal pain and hypersensitivity to touch nearby
  • Constipation
  • Bloating

You must visit your veterinarian for testing and a correct diagnosis before starting therapy because other illnesses and ailments sometimes accompany the signs of IBS in dogs.

The goal of IBS treatment is often to limit exposure to the factors that are contributing to the symptoms’ exacerbation.

For instance, it is well recognized that anxiety and stress can make the illness worse. To a large extent, symptoms may be avoided by taking measures to lessen stress or anxiety-provoking situations in your dog’s surroundings.

It will also be necessary to address any underlying medical conditions, such as inflammation or tumor. To reduce symptoms, a doctor may prescribe medication.

The gut and intestines can be calmed with the use of antispasmodic meds, and your dog can pass solid stool with the aid of anti-diarrhea treatments.

Additionally, there are drugs for constipation, gas, and bloating. You might wish to inquire with your veterinarian about different all-natural ways to minimize inflammation.

Dietary adjustments are typically part of ongoing therapy for IBS. High-fiber diets support maintaining the digestive system’s regular operation. 

3. Behavioral Issues 

Behavioural Issues Dogs

1. Eating Too Late or Too Soon 

Your dog may defecate at night if they eat their supper too late. They need to defecate once their system has digested the meal.

Try feeding them later if they are going potty at night despite being provided several hours before bed. This will make sure that they wait till morning to poop. 

2. Fear of Punishment 

Dogs don’t develop memories in the same manner that humans do. They instead create associations. If you or a former owner chastised your dog for going potty, your dog could be reluctant to go potty when you are present.

They can refuse to go potty outside throughout the day since they were reprimanded for doing so for doing it indoors. This is due to the dog’s lack of memory for the particulars of the incident.

They recall having a poop, being noticed, and experiencing adverse outcomes.

3. Being Shy 

A dog who is shy could also only go potty at night. When a dog poops, it is most susceptible. Many dogs choose to relieve themselves near their owners because they trust them to protect them when they are vulnerable.

While not for the same causes as people, other dogs appear timid. Simply said, they like to defecate alone, which is more likely to happen at night.

4. Distractions 

Some dogs get sidetracked easily. A lot is happening throughout the day, and the dog can be too engrossed in the activities to go potty. Things are calm and rather dull at night. Why not go potty because there is nothing else to do? 

5. Habits 

Dogs are routine-oriented animals. Once they become accustomed to a schedule, they frequently follow it. If your dog has developed the habit of going outside at night, they could keep doing so because that is when they are accustomed to going outside. 

6. Attention During the Night 

Only cats are more skilled manipulators than dogs. If your dog learns that getting you up in the middle of the night earns them additional cuddles and attention, they could keep doing it for your company alone.

The very first time they keep you awake to go potty, it could be cute, but you won’t find it as appealing after that. Unfortunately, your dog is unlikely to stop playing the game as long because it seems to be working.

7. Difficulty in Communicating 

Communication between you and your dog could be difficult. They have no choice but to go throughout the night if they need to relieve themselves before going to sleep, and you ignore the indications. 

8. House Training 

If you are house training him, it could take a while for your dog to cease pooping at night. Once you are there just to remember them during the day, they could be effective, but they won’t be able to manage it at night.

4. Anxiety and Stress

Dogs - Anxiety and Stress

1. Separation Anxiety 

According to several experts, this is the most typical cause of dog feces in houses. A dog with separation anxiety becomes extraordinarily nervous or worried when you leave.

When you are ready to leave the house, your dog will probably start to whimper and might try to stop you.

However, separation anxiety does not just happen when you are not physically present. Additionally, if your dog doesn’t have accessibility to you at night, it may occur when you’re asleep. When left alone, a person with separation anxiety will frequently poop.

    i really hope you can give me some advice, i await your kind reply with many thanks

    1. Hi James, sorry for what you are going through. When did you rescue him? Some dogs may experience anxiety when in a new environment, which can trigger frequent bowel movements, especially at night.
      You have mentioned that you have tried different dried foods, do you check their protein and fiber content?
      As for feeding time, feed him early enough before bedtime and then take him to the garden about 2 times before he goes to bed.

  2. Hey! My dog has been going outside for his before bedtime poops, but suddenly he wakes up multiple times in the night urgently to poop! It’s like he’s been holding it in for days! We just experienced our first snow, and he’s been eating the snow a little too much could that be a factor? Or is it just diarrhea? Help! I. Need. Sleep.

    1. Dogs eat snow and it’s perfectly okay if the snow is clean. However, if the snow is contaminated, it could lead to stomach upset and diarrhea especially when your dog is eating it in large quantities. I would prevent it from eating for a few days to see whether diarrhea stops. If it continues, consult your vet.
