Why does my dog only poop inside and not outside?

Reviewed by Amy Flowers, DVM on May 08, 2021

  • Medical Reasons
  • Aging
  • Separation Anxiety
  • Fear of Loud Noises

Even the best-behaved dog can go No. 2 in the house sometimes. If it happens more often than usual, your furry friend may have a problem. Illness, aging, and emotional issues could be to blame. But you should consider those causes only if you know your dog is housetrained -- in your home.

If you adopt an adult, housetrained dog, it may have accidents at first. A few reasons:

  • Stress
  • A new schedule
  • Not knowing how to “ask” you to go out

The problem should go away in a few weeks, when your new pet gets used to the family routine.  

It could be that your pooch isn’t well trained. Whether you have an adult dog or a puppy, you’ll need to teach them to do their business outside. Set a routine, watch your dog as much as you can, and have someone take them out if you’re going to be away.

When your adult dog starts to poop indoors out of the blue, it’s time to explore different causes.  

You may want to start with a call to your vet, especially if your dog’s stools are loose or if they have diarrhea. This could be a sign of gastroenteritis, when their stomach, small or large intestines are inflamed. Possible causes include:

  • Parasites like roundworms, hookworms, and giardia
  • Food intolerance or allergy
  • Bacteria
  • Viruses
  • Inflammatory bowel disease
  • Bowel cancer

There may be other medical reasons your dog poops indoors. That’s why it never hurts to rule out these problems first.

Have you noticed your dog poops more in the house as they get older? You aren’t alone. Older dogs often have fecal incontinence, or a lack of bowel control. Here’s why:

They can’t “hold it” like they used to.  As they age, they may need to go to the bathroom more often. They might also lose strength in the muscles that keep poop inside their body.

They forget to go. Your older pup may have a condition called canine cognitive dysfunction. It’s like Alzheimer’s disease in people. They could forget what to do on walks, then come inside and poop. Talk to your vet or a pet therapist about treatment options.

They have other health issues. One that affects mainly older dogs is called canine degenerative myelopathy. It often starts with hind-end weakness and can lead to incontinence.   

What can you do? When home, you can limit the mess by letting your dog out more often. When you’re away, hire someone to let them out, and keep them in a part of the house where cleanup is easy.

Pain or arthritis. It may be painful for them to posture to poop (the squatting position can be uncomfortable with any joint or muscle changes).

If your dog gets stressed when you leave the house, they could have separation anxiety. Signs include scratching at doors and windows, destructive chewing, howling or whining, and going potty inside the house.

Different dogs have different reasons for this panicked response. Some aren’t used to being alone. Others can’t handle a change in routine. Whatever the cause, there are steps you can take to lessen the problem:

  • Don’t make a big deal about leaving the house or coming home.
  • Talk to your vet about over-the-counter calming aids.
  • Ask the vet about prescription drugs that calm anxiety.
  • Confine your dog to a room with windows and toys to limit destruction.
  • Leave your dog with some recently worn clothes. Your smell can have a calming effect.

When dogs are afraid, they often pee or poop in the house. Loud noises, from the rumble of thunder to the boom and crack of fireworks, are common triggers. While you can’t stop the sounds outside, you can train your dog be calmer when they hear loud noises.

Create a safe and happy space. For dogs, a safe space will usually be dark and relatively small. It may be a closet, a crate, or even under your bed. Encourage (but don’t force) your dog to go there when loud noises strike. Provide treats or other rewards so they associate that space with happy things, not scary sounds.

Provide distractions. At the first sign of stress from loud noises, give your dog something fun to do. Play fetch with a tennis ball, offer a new squeaky toy, or practice commands with treats. Don’t expect to get rid of all their worries on the first try. The aim should be to delay fearful behavior longer each time.

If these problems and fixes don’t apply to your dog, don’t worry. Once your vet has ruled out medical reasons for dog poop indoors, a dog behavior expert can help you get to the root of the problem and help you fix it, too.

If your puppy refuses to poop outside, and instead holds their poop for in the house, then this post has got you covered!

Potty training a puppy is a process of determination and patience on the owner’s behalf. It can be trying when your puppy goes outside for their potty but only does a pee and holds their poop for inside.

By the age of 12-weeks your puppy should be old enough to potty train, or if they’re not quite ready, they aren’t far off. That’s because up until this time your puppy hasn’t had control over their bowel movements to know when to hold it and when to go.

If your puppy isn’t yet 12-weeks-old, then it’s likely your issue isn’t that your puppy only poops inside, but rather they just happen to be inside when it’s time to poop.

However, if your puppy is older than 12-weeks-old, then read on and we’ll get into the reasons why your puppy won’t poop outside.

Why does my dog only poop inside and not outside?

Why Your Puppy Won’t Poop Outside

Puppies won’t poop outside if they dislike the feel of grass, it’s cold, it’s raining, or they’ve been inadvertently trained to use their bowels inside. If you haven’t cleaned your house of puppy poop with an enzymatic cleaner, the smell can trigger your puppy to poop.

Your puppy may also have realized that when they poop outside, you bring them inside. They then can associate their pooping as the cue for playtime to be over, and so may hold their poop to stay outside for longer.

Or it could be entirely the opposite reason and your puppy dislikes going outside. This can be especially true if it’s winter and it’s cold or it’s raining. Or perhaps for whatever reason your puppy just prefers to be indoors where it’s comfortable, and when they’re comfortable, they’re at most ease to relax and do their business.

Another reason is that puppies are excited by new smells, sites, and sounds. When they’re outside they may be overwhelmed by their surroundings and find little time for pooping as everything is a distraction.

Your puppy may have also just learned that pooping inside is what they’re supposed to do. This can happen when pee pads are used in housetraining, and your puppy has learned to go potty indoors rather than out.

Finally, if you’re finding anything unusual about your puppy’s poop, then you should take them to their vet. If their poop is runny, or bloody, or if they’re not pooping 1 to 5 times a day, then they may have a medical issue going on which needs to be addressed.

A must-have for owners is a good odor eliminator. For this, we 100% recommend, Live Odor Free.

How to Avoid Accidents

You’re not going to stop all the inside accidents when your puppy is learning to poop outside. You can only do your best to catch them before they feel the need to go.

If they’re about to poop inside, swoop in and take them under the arms and carry them outside. They will find it difficult to poop in this position.

If they’re about to start and there’s no way you can get to them, use an interruption command, such as a high-pitched squeal to quickly get their attention. This can buy you the extra time to swoop in!

Once outside, place them in the desired location and say, “Go potty!” Be sure not to scold them or raise your voice through this process. You want to avoid causing any anxiety. Once they poop outside remember to tell them what a good puppy they are.

The last thing you want is your puppy feeling anxious when it comes to their pooping!

If you miss one and your puppy has done a poop inside, don’t scold them or put their nose up to it and tell them off. This will only lead to anxiety and bring about unwanted behaviors associated with this. Sometimes there’ll be poops that get through the gate during this training period, and that’s just part of being a new puppy owner.

How to Get Your Puppy Pooping Outside

I just want to quickly jump in here and say we’ve created a mobile-friendly speedy video course on dealing with unwanted puppy behaviors, and one of the modules is exactly about this issue, so be sure to check it out here.

How quickly and easily it is to train your puppy to go potty outside will depend on the reason behind your puppy’s indoor pooping. By using the following training suggestions, you should have little problem in teaching your puppy your desired outcome.

Anticipate Your Puppy’s Poop

In order to have control over your puppy’s pooping habits, you first need to have an awareness of when they’re most likely to go. The more often you catch them before the act happens, the more likely you’ll be able to direct their business to the outdoors.

Your puppy will generally eliminate within 30-minutes after every meal. If you’ve been doing a training session with them feeding treats this will also start the clock on your puppy’s digestive system.

Your puppy will poop anywhere from 1 to 5 times a day, and this will depend on how frequently you feed them or give them treats. If they’re eating three or more small meals a day, or you feed your puppy by leaving out their daily food and they snack all day long, then these pups will poop more regularly.

Be watchful of their behavior leading up to a poop and learn the signals. These behaviors can be subtle, so watch for ritualistic actions before they go. Perhaps doing a few circles or sniffing the ground.

It’s also a good idea to chart their pooping schedule. It doesn’t need to be marked out in seven shades of highlighters. Just a daily notepad keeping track of their habits, so you have a good idea of how many times they go as well as what they were doing beforehand.

They will often go in the morning, after meals, after playtime, and after long naps.

Leash Method

Once you have a good handle on when they’re likely to go, you can take them outside during these probable times.

We recommend leashing them, taking them outside and walking around a little. Take them to a desirable location, then say, “Go potty!” or “Wees and poos!” It doesn’t matter what it is, as long as it’s always the same.

Now you play the waiting game. If they go, praise them, and show them how happy you are. Now let them off the leash for a run around.

It’s important that you don’t take them straight back inside at this point. If you do, they may associate their pooping as the reason for being taken back inside, and so they’ll hold it in next time.

Use Enzymatic Cleaner

When your puppy does poop in the house, be sure to always use a cleaner that will completely remove the smell of your puppy’s poop. They have an ultra-sensitive sense of smell and being able to smell their own poop in the house will send a signal to them that this is the place to poop.

We like Nature’s Miracle Advanced Dog Stain & Odor Remover as it’s a ready-to-go spray solution that will eliminate any odors.

Crate Train Them

If you haven’t done so already, crate training a puppy is a great tool for house-training, as well as giving your pet a sense of security. Puppies love to know they’re safe and a crate is a spot that’s all their own.

The reason why crate training assists in house-training is your puppy will be reluctant to poop in a small area they occupy. This will teach them to hold their bowels.

Whenever you take your puppy from their crate, carry them outside, or you can use a leash and follow the directions under the leash method. If you just let them out of their crate, they won’t wait to go outside before pooping, so be quick to take them to the desired location.

Go for Walks

Puppies are too young to take for long walks, but a short stroll is a good way to get them using their bowels outside. This is especially important after meals.

This chart shows how long you should walk your puppy, though this is only a guideline. Some breeds, such as cattle dogs, can go above this recommended time.

Puppy Age (months) Exercise Time (minutes)
1 5
2 10
3 15
4 20
5 25
6 30
7 30+

By taking them often for little walks around the yard or up the street, you will give them plenty of opportunities to poop outside.

When they poop remember to say “Go potty” so they associate your words with pooping, so you can use the magic words when you’re not walking them. When they poop be sure to reward them generously!

Go Outside Often

Your puppy will be a poop machine early on as they don’t have control over their bowels. Even though you can’t truly train them until they have that control (at 12-14 weeks) you can start associating their pooping with the outdoors.

At any age, and especially during house-training, take them outside as much as you can. Once every hour is a good guide, and although that might seem like a lot, your early work will pay dividends later on.

Are They Comfortable?

When your puppy poops, they can feel vulnerable. If they have any anxiety at all when they’re outside, they’re more likely to hold it and poop inside. Is there a dog next door that’s a little scary? Or loud noises? Or is there a particularly large object that they don’t go near? All these things can be deterrents to your puppy.

This is why it’s so important for you to spend as much time as you can outdoors with them. You can feed them outside, play with them, walk them around the yard with a leash, do your training outside, and most importantly, use treats outside.

All these things will improve their perception of outdoors and make them more likely to go potty.

And if you’re still concerned about your dog’s housetraining progress, we recommend you check out this program that can housetrain a dog in under 7 days.

When It’s Raining and Cold

A puppy will definitely be less inclined to poop outside when it’s raining or during the winter season. And if it’s snowing then you’ll have an even harder time.

It’s important to teach them that the rain isn’t their enemy. Next time it’s raining, be sure to grab your raincoat and the leash. Take them for a small walk and be generous with your praise. Your puppy will soon love the rain!

If it’s snowing, be sure to put some boots on their feet so it’s not too cold for them. Then likewise with the rain, spend some time with your puppy outside when there’s snow.

Clear an area of the snow too so they can smell where their poop has been before. It will also give them a more comfortable location to get into position.

It’s a good idea to get them a warm jacket for the colder weather.

The more time you spend outside with your puppy, the more they will love it no matter what. Get yourself some warm clothes and be sure to go walking… rain, hail, or shine. Well, maybe not hail!

Final Word

If you’re finding anything unusual about your puppy’s poop, then you should take them to their vet. If their poop is runny, or bloody, or if they’re not pooping 1 to 5 times a day, then they may have a medical issue going on which needs to be addressed.

If it’s behavioral, then the best way to teach a puppy anything is through positive reinforcement. This is because they love praise; they want to be good dogs!

The more you show them that outside is a positive environment the more likely they will poop outside. From personal experience, I’ve used the leash method to great success.

As always if you have any additional concerns be sure to visit your veterinarian.
