For years, I’ve been asked the same question: Why is my 6-month-old dog urinating in the house again again?

“My dog is potty trained, but he’s still having accidents in the house!” one of my pals would exclaim.

For many years, I assumed the most apparent solution was straightforward: your dog may seem to be toilet trained, but he is not.

  • Take a step back with your puppy’s toilet training.
  • Don’t offer your dog as much freedom in the home as you would want.
  • Also, take him out whenever he wakes up, after each meal, and every 10 minutes while he’s playing.

That was my opinion until we brought home Elsa, our most recent dog…

What’s the Deal With My Puppy’s Accidents?

Over the years, I’ve reared hundreds of pups and followed the same toilet training process with each one.

Around the age of four months, the majority of my pups were toilet trained. Aside from the one-offs, I had very few if any mishaps once they reached the magical 4 month mark:

  • Linus had a couple accidents in the home while he was unwell.
  • Stetson, unlike Linus, couldn’t hold his pee for more than 6 hours. He’d have an accident if he was ever left home alone for a lengthy amount of time.
  • Stetson drank a lot of water while on prednisone. It was really difficult to anticipate when he needed to go pee during this time. After just being home alone for less than an hour, he had three accidents!
  • Adelle was suffering from a urinary tract infection and was having home accidents.
  • Kona used to dribble all over the home throughout her first several years. She was also renowned for urinating when she got thrilled.

These are just a few examples of our dogs having accidents in the home after being taught to use the toilet. Elsa, on the other hand, shocked me by doing something different than any other puppy after almost 16 years of rearing pups. It’s not in a nice manner…

QUICK RECOMMENDATION: We always use an enzymatic cleaner to make sure we get rid of any lingering pet odors. Our favorite is Rocco & Roxie’s Stain and Odor Remover.

Potty Training Regression in a 6-Month-Old Puppy

Elsa, like every previous dog we’d reared, was toilet trained by the time she was four months old. For the last two months, I haven’t had a single accident in the home.

Then it occurred just around my birthday. She leapt onto our bed, crouched down, and peed!

What the hell is going on!? After two months of no accidents, she pees on our bed!

I couldn’t believe what I was hearing. I had never previously had a puppy urinate on our bed. Elsa was not even permitted to sleep on our bed.

I did what I said I was going to do over the following several days. I took a step back, restricted her movement around the home, and made sure she didn’t have another accident. I also had her urinalysis done to rule out a urinary tract infection.

She went into heat a few days later, so I attributed it to hormones.

Potty Training Regression in an 8-Month-Old Puppy

Until she was eight months old, Elsa’s unexpected accident remained a distant memory.

This time she dashed over to her warm and inviting canine bed, crouched, and peed!

“@:#!!! What the!”@:#!!! bleep bleep bleep bleep bleep bleep bleep bleep bleep bleep bleep blee

After 2 months of no incidents, there was another one!!!

Hormones could not be blamed this time. Why did Elsa have an accident while she was toilet trained (as far as I knew)?

For a week, we took a step back, restricted her mobility, and made sure she didn’t have any accidents. Everything seemed to have returned to normal, or so I thought.

Potty Training Regression in a 9-Month-Old Puppy

I was losing faith in Elsa’s ability to understand she wasn’t supposed to go pee in the home at this point. However, after a little more than a month, I started to relax my guard, till…


She hopped on our brand new bean bag this time, squatted, and peed!!!

Now, remember what George W. Bush said:

“There’s an old saying in Tennessee that goes, ‘Fool me once, shame on…shame on you.’ I know it’s in Texas, but it’s definitely in Tennessee. ‘Fool me once, and you’ll never be tricked again.’

Wikipedia – Bushisms

Because I’m an idiot, there must be a proverb for “fool me three times,” or I’ll have to invent one.

Anyway, after Elsa had deceived me for the third time, I sat down and pondered why she was still having accidents in the home despite being apparently “potty trained.”

SPOILER ALERT: Jump to potty training tip #8 below if you want to skip straight to why Elsa was peeing in the home after being potty trained.

Why has my puppy begun peeing in the house once more?

Let’s start at the beginning with reasons why your dog could be experiencing home accidents again:

1. Your puppy hasn’t been trained to use the toilet.

Many owners attempt to push their pups through toilet training too early and give them too much freedom in the home. As a consequence, your puppy understands some, but not all, aspects of toilet training.

As a consequence, kids may still have accidents in the home, but not as often as when you initially began working on their toilet training.

2. Your puppy is still young and has no control over his bladder.

A 6-month-old puppy’s bladder control is typically not an issue. However, I often hear from customers who report that their 8-week-old puppy, 10-week-old puppy, 12-week-old puppy, or 14-week-old puppy is still having accidents in the home.

Potty training may begin as early as 10 weeks old in some remarkable pups. Most people, however, will not have complete bladder control. A young dog may not realize he has to go pee until it is too late.

3. Your Puppy Isn’t Feeling Well

Linus got ill numerous times and had diarrhea accidents in the home. Your puppy may not be able to control his bowels (or pee, as in point #4) if he is unwell.

If your puppy becomes ill, take him to the veterinarian for an appropriate diagnosis and treatment.

4. Urinary Tract Infection in Your Puppy (UTI)

This was split from #3 since it’s a prevalent cause of home accidents.

Puppies with Urinary Tract Infections often have trouble holding their urine. As a consequence, there was an accident in the home.

If you think your dog’s accidents are caused by a urinary tract infection, see your veterinarian for a correct diagnosis and treatment.

5. Your Puppy Is Overjoyed

Kona, our friend’s Dachshund/German Shepherd mix, was in such a bad way. She used to have excita-pee, as we called it.

She’d get so thrilled every time I came over that she’d have an accident in the home.

The idea is to ignore the puppy when you arrive home so that she does not get too enthusiastic. Give her some calm praise and a treat after she has calmed down.

6. Your Puppy Is Having Urinary Problems

Incontinence is the inability to regulate urine or excrement on one’s own.

We won’t go into great depth concerning canine incontinence. If you think your dog’s accidents are caused by incontinence, see your veterinarian for a correct diagnosis and treatment.

7. Your puppy won’t be able to hold it for long.

We brought Linus camping when he was 9 months old. He refused to urinate on the ground and held it for more than a day. Finally, like Tom Hanks in A League of Their Own, he let it all out.

Stetson, unlike Linus, couldn’t hold his pee for more than 4-6 hours. He’d often have an accident if he was ever left home alone for a lengthy amount of time.

Each puppy and dog is unique. Even as adults, some people can keep it for what feels like an eternity, while others can only hold it for a few hours.

8. Your puppy has to go potty, but you didn’t have time to take him outside.

Now, let’s return to Elsa’s narrative.

After a lot of thought about our 6-month, 8-month, and 9-month potty training mishaps, I came to the Conclusion that Elsa was potty trained, but she didn’t communicate with us as our previous dogs did.

Linus, Stetson, and Raven would all sit by our patio door, waiting for us to open it and let them out. This was their way of informing us that they needed to go outdoors and pee.

When we let them out, they would do their business right away and then wait at the door to be allowed back in.

Elsa seldom stood at the door, waiting to be invited in. While she waited from time to time, we usually simply let her out when Raven stood at the door. When Raven waited to be allowed back in, they were let back in.

What occurred was that Elsa didn’t always go pee when we let her out with Raven, and her indication that she needed to go outside was being extremely active, pacing back and forth, and placing her head on our lap.

This was/is a difficult signal to interpret, and since we didn’t, we assumed she was simply being a regular energetic zoomie puppy jumping about until she had her accidents.

What is our solution? There are two key aspects to consider:

  1. Rather than allowing her to go pee on her own. When we let her out, I began leashing her and made sure she peed or pooped. We followed this procedure with all of our guide and service dog pups, although we were a bit more lenient with Elsa when it came to potty training.
  2. We bought a Smart Bell and started teaching her how to use it when she needed to go outdoors. A obvious indication that she needed to go toilet.
  • Solution #1 – making sure she went pee before we put her outdoors worked since we haven’t had an accident in over four months.
  • Solution #2 – is still in the works, but a clear notice from her that she has to go potty will help us prevent any future mishaps.

Your Puppy Is Drinking A Lot Of Water

We were discussing this with the veterinarian at our local guide dog meeting when he mentioned it. He claims that some pups achieve a point of comfort in their new homes around the age of 4-6 months.

He believed that since kids were more at ease at this age, they were more likely to overdrink water (drinking a lot at once) and then have accidents in the home.

This happened to our current dog, Anna, once. I recall her “loading up on water” when she was approximately 4 12 months old. She’d then pee many times over the course of a 30-minute period. Some of them were on the exterior, while others were on the inside. I recall her peeing seven times in roughly 30 minutes and wondering aloud what the hell was going on!

One of our guide dog group’s advice is to constantly keep fresh water accessible for your puppy so that he or she does not feel the need to “load up on water.”

Your Puppy Is Teething No. 10

What else occurs to your dog between the ages of 4-6 months? Teething starts for your dog!

Is it possible that teething is to blame for toilet training failure? Yes, to put it simply. The lengthy answer is that teething is a painful experience for your dog. When you don’t feel well, it may interfere with particular habits, just as it does with everything else. In this scenario, we’re talking about toilet training.

Puppy Peeing In The House Again – Frequently Asked Questions

Is It Normal For A 6-Month-Old Puppy To Get Into Mistakes?

We’re constantly curious about what’s typical for our pups. I’m sure I do. I have my own opinions about what is “normal” after raising over a dozen service dog pups.

Is it reasonable to expect a 6-month-old dog to have accidents in the house?

NO, I do not believe this is usual. If you begin potty training your puppy when he is approximately 8-10 weeks old, he will almost certainly be potty trained by the time he is 6 months old. However, as we discussed earlier in this article, there are a variety of reasons why your puppy’s toilet training may regress.

What Is The Maximum Time A 6-Month-Old Puppy Can Hold Pee?

To answer this question, consider the following scenarios:

1. You put your pet in his kennel for the night. Your dog should be able to hold his urine for at least 8 hours without having an accident.

2. You should keep your puppy in a kennel throughout the day. We are not allowed to kennel our 6-month-old pups for more than 4 hours throughout the day, according to the guide dog school. Our dog will keep his pee for at least 4 hours, and most likely longer if necessary.

3. Your dog is playing with other pups in the yard who have access to water. In this circumstance, I’d anticipate my dog to urinate every 30 minutes or so.

4. Your pet is left alone at home and is free to wander. Every puppy is unique. Our older dogs are free to explore the house, but I wouldn’t leave them alone for more than 3-4 hours. While I wouldn’t leave a 6-month-old dog alone in the home, I wouldn’t trust him to contain his urine for more than 1-2 hours if I did.

The moral of the tale is as follows: If your puppy is awake and active, and he has access to water, he will need to go to the bathroom regularly. He will be able to hold his pee for much longer if he is in his box and napping.

Why is my six-month-old puppy peeing all over the place?

Many things might cause a 6-month-old dog to “appear” to be peeing everywhere:

  1. Your dog is suffering from a urinary tract infection, which may lead him to urinate at inconvenient times.
  2. Your dog drank a lot of water — after consuming a lot of water, our present puppy, Anna, peed seven times in 30 minutes!
  3. Your dog is playing — pups pee every 5 minutes or so while they’re playing.
  4. You’re not keeping an eye on your dog, and puppies pee a lot. If your puppy isn’t toilet trained, you should keep a close check on him at all times while he’s inside. Get your puppy outdoors when he exhibits pre-potty behaviors (circling, smelling, crouching).

The four options listed above are the most prevalent. There are ten causes for a puppy urinating in the home again on our main list, and they would most likely apply to this situation as well.


We’ve had it easy. Raven, Linus, and Stetson were all quick to learn to use the toilet. We’ve also successfully potty trained over a dozen additional pups who went on to serve as service dogs.

Elsa was an exception. We found an obvious answer to the issue by taking a step back and truly thinking about why she was having accidents in the home.

Our ultimate answer was to keep her on a leash and make sure she did pee outside every time we took her out.
