You thought you had it all figured out. Your adorable furball was finally peeing outside consistently and you were celebrating the end of middle-of-the-night cleanup sessions. Then suddenly – puddles on the carpet again! If you’re wondering “do puppies regress with potty training?” the frustrating answer is absolutely yes.

As a dog parent who’s been through this multiple times, I can tell you potty training regression is super common and usually fixable with the right approach Let’s dive into why your “fully housebroken” pup is suddenly having accidents again and what you can do to get back on track.

What Is Puppy Potty Training Regression?

Puppy potty training regression happens when a previously house-trained pup starts having accidents indoors again. It’s that maddening moment when you think your dog has finally mastered where to do their business, only for them to forget everything they’ve learned.

An animal wellness study has shown that potty training regression is especially common in puppies between four months and one year old. During this time, their brains are still developing, and their memories aren’t as strong as adult dogs.

When Potty Training Regression Typically Happens

Regression tends to happen at specific developmental stages:

  • 4-5 months old: This coincides with rapid brain development, when puppies might seem to forget previously learned behaviors
  • 7-9 months old: Especially common in male dogs as testosterone levels increase with sexual maturity
  • 10+ months old: Often related to hormonal changes as puppies transition to adulthood

As Kevin Ryan, a professional dog trainer with over 30 years of experience, notes: “It’s frustrating when your puppy regresses in their house training, but it is common and usually easily fixed with a back-to-the-basics approach.”

Signs Your Puppy Is Experiencing Potty Training Regression

How do you know if your puppy is truly regressing or just having an occasional accident? Look for these patterns:

  • Repeatedly using the same indoor spots – They can smell their previous accidents, even if you can’t
  • Having accidents while you’re away – This could indicate they’re alone too long
  • Going outside but not actually pottying – They might just want to play
  • No longer signaling when they need to go – They’ve forgotten their training
  • Overnight accidents – Might be drinking too much before bed or feeling anxious

Common Causes of Puppy Potty Training Regression

Understanding why regression happens is the first step to fixing it. Here are the most common culprits:

1. Inconsistent Rewards and Training

We’ve all been there – your pup is doing great for a few days, so you relax your vigilance. You stop rewarding outdoor potties or watching them as closely. Suddenly, accidents happen! Consistency is key in potty training, and slacking off too soon is a recipe for regression.

2. Developmental Stages and Hormonal Changes

Just like human kids, puppies go through various developmental stages that impact their behavior. Their brains are literally rewiring, and sometimes potty training gets temporarily lost in the shuffle.

3. Anxiety and Stress

Dogs thrive on routine and predictability. Changes in their environment can trigger anxiety, which often manifests as potty accidents. Common stressors include:

  • Moving to a new home
  • Adding a new pet or family member
  • Changes in your work schedule
  • Loud noises like fireworks
  • Being left alone too long

4. Medical Issues

Sometimes regression isn’t behavioral at all but stems from a health problem. If your adult dog suddenly starts having accidents with no other obvious cause, it’s time for a vet visit. Common medical causes include:

  • Urinary tract infections (UTIs)
  • Bladder or kidney stones
  • Inflammatory bowel disease
  • Diabetes
  • Gastrointestinal issues

5. Not Thoroughly Cleaning Previous Accident Spots

Dogs have incredible noses – they can detect scents we can’t even perceive. If you haven’t completely eliminated the smell of previous accidents, your pup will be drawn back to those spots. This is why enzymatic cleaners are essential!

7 Steps to Fix Puppy Potty Training Regression

Don’t despair! With patience and consistency, most potty training regressions can be fixed. Here’s how to get back on track:

1. Go Back to Basics

Pretend your dog is a brand-new puppy again. Set up a consistent routine with frequent potty breaks, especially after meals, naps, and playtime. One trainer I spoke with recommends: “Sometimes just taking a step backwards in your house training, reestablishing a routine, and proceeding from there can reset your pup from their training regression.”

2. Clean Thoroughly With Enzymatic Cleaners

Regular cleaning products won’t completely eliminate urine odors. Invest in an enzymatic cleaner designed specifically for pet accidents. These break down the urine molecules rather than just masking the smell.

3. Establish a Strict Schedule

Feed your pup at the same times each day, which helps create predictable potty times. Take them out:

  • First thing in the morning
  • After meals (within 30 minutes)
  • After naps
  • After playtime
  • Before bedtime
  • Every 2-3 hours in between

4. Use Positive Reinforcement

Throw a party when your pup goes outside! Give lots of praise, treats, and excitement. Never punish accidents – this can make your dog afraid to go potty in front of you, leading to hidden accidents.

5. Consider Crate Training or Confinement

When you can’t supervise your pup, a properly sized crate or playpen can be invaluable. Dogs naturally avoid soiling their sleeping areas, which reinforces holding their bladder until they can go outside.

6. Keep a Potty Training Diary

Record when your pup eats, drinks, and eliminates to identify patterns. Note any accidents – where they happened and what was going on beforehand. This can help you spot triggers and adjust your approach.

7. Try the In-and-Out Method

If your dog doesn’t go potty when you take them outside, bring them back in and put them in their crate or confined area for 10-15 minutes, then try again. Repeat until successful. This teaches them that outside time is for business first, play second.

Common Mistakes to Avoid During Re-Training

When addressing regression, watch out for these common pitfalls:

  • Punishing accidents: This creates fear and anxiety, making the problem worse
  • Inconsistent schedules: This confuses your pup about when and where they should go
  • Too much freedom too soon: Gradually increase freedom as your dog shows reliability
  • Not supervising closely enough: If you can’t watch them, they should be confined safely
  • Giving up too soon: Regression is frustrating, but persistence pays off!

When to See a Vet

While most potty training regression is behavioral, sometimes there’s an underlying medical issue. Contact your vet if:

  • The regression is sudden and severe
  • Your adult dog (over 1 year) starts having accidents
  • You notice changes in water consumption or urination frequency
  • There’s blood in the urine or stool
  • Your dog seems to be straining or in pain when eliminating
  • Accidents happen even when your dog has just been outside

Real-Life Success Story

I remember when my Lab mix, Charlie, went through a terrible regression phase at about 8 months old. After being perfectly potty trained for months, he suddenly started having accidents every day. I was pulling my hair out!

After ruling out medical issues, we went back to basics – regular schedule, crate when unsupervised, and mega rewards for outdoor potties. Within two weeks, he was back on track. The key was consistency and patience (and lots of enzymatic cleaner!).

Final Thoughts on Puppy Potty Training Regression

Potty training regression is a normal part of puppy development. When it happens, take a deep breath, adjust your expectations, and go back to the training methods that worked initially. With consistency and patience, most dogs quickly get back on track.

Remember what one expert says: “Puppy brains are still developing, so their training will not always be reliable during this period. Just take a step back or two in their house training, stick to the basics that worked initially, and you should be back on track soon.”

It is a known fact that between something like 8 – 12 months is when puppy’s will regress in their training because they’re testing how much they can get away with. Its important to reinforce training during this time and to be consistent.

Why is my puppy suddenly peeing in the house again?

Your puppy may have started peeing inside again due to a medical issue like a urinary tract infection, stress from a new environment or routine change, a regression in potty training, or behavioral reasons like territorial marking or submissive urination. First, consult your vet to rule out health problems, then address potential behavioral issues with consistent training and a clear routine.
