Karen PiwinskiYour puppy seems to be fully house-trained, and you’re finally enjoying a clean home. But suddenly, you discover a puddle on the carpet or a mess in the hallway. You can’t help but start wondering, “Why is my puppy now struggling with potty training?” Don’t worry, you're not alone. Many pet owners report their puppies regressing to an earlier phase of their potty training.
There is good news, though. This setback is very common, temporary, and fixable with the right approach
Key Takeaways
- Puppy potty-training regression is a normal part of the developmental process
- The most common causes are stress and anxiety, an inconsistent routine, and insufficient training
- Going back to basics, consistent routines, and increased supervision help puppies re-learn proper habits.
Understanding why a puppy has regressed in potty training is the first step to getting back on track. Below, we’ll explore the common causes of potty-training regression. We’ll also discuss practical tips on how to help your companion succeed once again.
What Is Potty Regression in Puppies?
Puppy potty-training regression happens when a previously trained dog starts having potty accidents inside the house again. The regression is a temporary disruption in their established potty habits.

It often happens between four and twelve months of age. These accidents might happen in the spots where they previously had problems or in completely new places. The frequency can also vary – from occasional slip-ups to daily incidents.
Why Is My Puppy Regressing in Potty Training?
Understanding the cause of your puppy’s going backwards in potty training is essential. Let's explore the most common reasons behind these setbacks.
Normal developmental stages
Puppies go through various developmental stages that impact their behavior, including their potty-training habits. Your puppy, depending on the breed, enters adolescence between 4 and 7 months of age. This period is characterized by rapid brain development and hormonal fluctuations.
Many dog owners note a puppy house-training regression exactly at the 4-to-5-month mark. Another regression is usually between 7 and 9 months. According to the AKC, puppies can’t fully control their bladder until they're 16 weeks old. For dog parents, this means that their young dogs are more prone to such accidents.
Stress and anxiety
Changes in your puppy's routine or a new environment can trigger stress. And stress can manifest as potty accidents. The following factors can distress your puppy:

- Loud noises, such as fireworks or thunderstorms
- A new family member, guests, or a new pet at home
- Separation anxiety
- Household changes.
When puppies feel anxious or upset, they may lose control of their bladder or bowels. As a result, they might pee or poop indoors as a way to cope with overwhelming emotions.
Inconsistent training
When the potty-training schedule varies, a young dog can’t reliably connect outdoor toileting with positive reinforcement. After succeeding with puppy potty training, many owners usually become less observant. What does that mean?
- You might stop rewarding every potty trip outdoors
- You might extend the time between potty breaks
- You might supervise your puppy less.

Young dogs, including teenage dogs, need consistent reinforcement to strengthen their understanding of where and when to go toilet. If the schedule becomes unpredictable, your puppy will struggle to maintain good habits. Different family members using different methods may also cause confusion and regression.
Lack of supervision
When puppies have full access to your home without supervision, they're more likely to pee in inappropriate places. There’s simply no one to redirect them to the proper potty area. In addition, puppies have short attention spans – they may get distracted during play and forget they need to go outside. Since they’re still developing, they might not be able to signal when they need a bathroom break. Without supervision, accidents will happen, with each potty accident reinforcing the wrong behavior.
Even if your puppy seems to be trained, be careful to watch them closely. They often learn to go behind the couch or in other areas where they’re not carefully monitored.

Urinary tract infections (UTIs)
Underlying health issues, such as urinary tract infections (UTIs), can often manifest as puppy house-training regression. UTIs cause inflammation of the urinary tract. As a result, most puppies have an uncontrollable urge to pee frequently. Other symptoms suggesting that a vet check is needed include:
- Struggling to urinate
- Producing small amounts of urine
- Having blood in the urine
- Acting reluctant to go outside
- Acting like they’re in pain when they do urinate.
If your puppy's regression appears suddenly despite a consistent routine, consult a vet. Veterinarians are able to rule out whether it’s a medical problem or a behavioral one.
Other health issues
Other health conditions that can cause potty regression include:
- Gastrointestinal issues
- Intestinal parasites
- Diabetes
- Kidney disease
- Bladder stones
- Urinary incontinence
- Inflammatory Bowel Disease.

All of these medical conditions can cause discomfort and an uncontrollable urge to pee. Dietary changes or food sensitivities can also lead to puppy potty-training regression. A change in diet can increase peeing frequency or make it difficult for the puppy to hold it until the next potty break.
Medical issues often come with additional symptoms, such as:
- Increased sleepiness
- Changes in appetite
- Lethargy
- Vomiting
- Pain or visible discomfort.
If you notice any of these signs apart from potty regression, a vet visit should be a priority.
How to Handle Potty-Training Regression in Puppies
Below you’ll find several strategies on how to deal with puppy house-training regression. These strategies will help dog parents to guide a puppy back to success.
Consult a veterinarian
The first thing is to identify if potty accidents are caused by medical or behavioral issues. If accidents persist despite increased supervision and consistent routines, a veterinary exam is essential. Schedule an appointment if your previously potty-trained puppy suddenly starts having accidents. The presence of any additional symptoms like straining, behavioral changes, or blood in the urine is a warning sign.

Additional tests can help rule out digestive issues. Some of these include: UTIs, parasites, and other health problems. With the right treatment, health-related regression usually resolves in no time. Early detection of underlying medical issues prevents them from turning chronic or very painful.
Clean accidents properly
Enzymatic cleaners are a preferred choice for dealing with potty accidents. They eliminate the scent of past accidents as opposed to regular household cleaners that only mask the odors. Most dogs have strong scent-tracking skills, which allow them to detect scents. The residual smell will encourage them not to pee in the same area again, as it will no longer be there.
As soon as you discover the pee, clean the accident spot thoroughly. Make sure you follow the product instructions for the special enzymes to work properly.
Go back to basics
Treat your pup as if you're beginning toilet training from scratch. Return to basic routines that help puppies re-learn bathroom habits. This includes:
- Having frequent outdoor breaks (preferably, every 1–2 hours)
- Add potty breaks immediately after meals
- Potty breaks should also be after naps and play sessions.
Make sure to use a leash when you’re outside. This allows you to ensure they’re not distracted by anything else. Reward your pup right after you’ve finished. Don’t forget to restrict access to areas where previous accidents have happened. A crate, a baby gate, or even simply closing the door to limit their space will work.
Don't become upset with your puppy if they regress when it comes to house training. They just need time, understanding, and patience. This will help them get back on the right track.

Manage stress
Create a calm and predictable environment for your puppy. Maintaining consistent routines for daily activities will create a sense of predictability and security. Potential stress triggers can include, but are not limited to:
- Separation anxiety
- Loud noises
- New environments
- New people or pets.

Provide plenty of physical and mental exercise, as it helps to reduce anxiety. Consider products that promote calmness, including calming anxiety wraps or puzzle toys. Scent work can also help to calm pups. Spending quality time with the pup will reinforce your bond and provide the reassurance they need.
Be consistent with rewards
Your puppy needs continued positive reinforcement to maintain proper potty habits. Reward every successful puppy potty training outdoors with immediate praise and treats. The reward must come right away to make a clear association between the behavior and the outcome. Use high-value treats that your puppy finds especially motivating, not just their regular kibble.
Consistency applies to everyone in your household. Make sure all family members follow the same routine, use the same commands, and provide rewards for successful potty breaks. Mixed messages from different people will slow your puppy's progress.
6. Increase supervision
Close supervision is crucial when dealing with a puppy that has regressed in potty training. It’s better to keep an eye on your puppy at all times when they're not crated. Watch for signals that might indicate an urge to pee, such as:
- Sniffing intensely
- Circling
- Whining
- Heading toward the door.
As soon as you see the following signs, take your puppy outside right away. If supervising your pet is challenging, try using a crate or an exercise pen. It can help to prevent potty accidents and reinforce elimination outside.
Phone apps can also be a useful tool for puppy potty training. The Woofz app is one of them, helping you track your puppy's potty schedule. It has many useful features, like the ability to set potty break reminders and monitor behavioral patterns during accidents.
You can log every successful potty break and accident, note the time and details of each. The Woofz app allows multiple family members to log in and stay coordinated, ensuring everyone follows the same routine.
Wrap Up
Discovering that your puppy is regressing in potty training can feel frustrating after all the progress you've made. But remember: regression is temporary. It’s a normal part of the process that most puppy owners experience during adolescence.
The key to managing the regression is understanding the causes, ruling out medical conditions, and returning to consistent routines. Clean accidents with enzymatic cleaners, increase supervision, and continue rewarding every small success. With patience, consistency, and the right tools, you'll guide your puppy back to proper potty training.
