Why Is My Dog Suddenly Peeing In The House?

When you have a dog, it is normal for accidents to happen.

A friend of mine recently shared that her adult training dog suddenly started peeing in the house.

She did some research.

She found out that dogs can suddenly pee in the house regardless of their life stage: puppy, adult dog or senior dog.

And there are many reasons for this change in behavior.

When your dog starts peeing in the house, the issue should be addressed as soon as possible. 

Why is my dog suddenly peeing in the house? Peeing in the house is quite a common problem with dogs, however, it is usually taken care of when they’re puppies. If your adult dog is peeing in the house, this could be due to a number of behavioral or health issues including urinary tract issues, old age, or excitement. 

While it’s quite common for a dog to occasionally pee in the house, if it is becoming a problem, you want to address the issue and determine the cause.

We will go over some of the most common health and behavioral causes for sudden peeing in the house. 

Why Is My Dog Suddenly Peeing in The House?

Below is a list of possible reasons why your dog may be peeing in the house, the symptoms to look out for, and the treatments for each cause. 

Dog urinating in house (medical reasons)

Urinary tract problems (including infections)Frequent urination, whining while urinating, blood in urine, licking genitals, strong urine odorAntibiotic medication, pain medication, change of diet
Incontinence Leaking or dribbling urine, urine puddles during napsVeterinary medication
Old ageSigns of dementia, accidental urinationMedications and supplements, doggie diapers, lined bedding, absorbent pads

Urinary tract problems

If your dog is urinating frequently or seems to be in pain when urinating, this is likely a sign of a urinary tract infection.

These can be quite common in dogs and can be diagnosed and treated by your vet. 


This is more common in older dogs but can also happen to younger dogs.

Dogs that experience incontinence don’t know that it is happening and don’t have any control over their toileting.

It is usually treated with medication from your vet. 

Old age 

Older dogs can often experience dementia or may become senile, causing them to forget where they are.

This can result in some accidents inside the house.

This can usually be managed with medications and supplements.

Some people may also choose to use absorbent pads or doggie diapers to protect the house from these inevitable accidents.

Dog urinating in house (behavioral reasons)

There are five behavioral-based reasons why your dog has suddenly started peeing inside the house.

MarkingPeeing on things, marking spots with urineRe-training, increased potty breaks
Submissive urinationUrinating when intimidatedRe-training, avoid standing over the dog, avoid shouting at or around the dog
Excited urinationUrinating when excited Re-training
Changes in the homeUrinating due to recent changesRe-training
Outdoor situationsAvoiding urinating outdoors, being scared to go outsideRe-training, comforting, reassuring 

These reasons go some way to answer 2 questions you may have “Why does my dog pee in the house in front of me?” and “Why is my dog peeing in the house when the door is open?”


Male dogs will often display marking behaviors which include peeing on things to mark their territory.

This is driven by the male’s sex hormones and can be treated through increased training and more frequent potty breaks

Submissive urination

This occurs when your dog is feeling scared or intimidated

The best course of action to avoid submissive urination is to try re-training your dog and avoid situations where he may feel scared or nervous. 

Excited urination 

This occurs when your dog gets a little bit too excited – a little bit of urine may leak out.

I find this can happen as I walk through the front door at night after work. It’s crazy! 

The best thing you can do to prevent excited urination is to re-train your dog. 

Changes in the home 

Your dog may respond to certain changes in the home by peeing in the house. 

Has something changed recently, such as adding a new pet, a new baby, or has someone recently passed away? 

Dogs are sensitive to these situations and the best thing you can do is resort to re-training them according to these changes.

This may lead them to avoid wanting to go outside and they will resort to peeing indoors instead. 

The best thing you can do in this situation is re-train your dog.

You should also accompany them outside for reassurance and comfort them if they seem uneasy.

Dogs can get so stressed, they can scratch or lose hair excessively!

Moving home also exposes your dog to new sights, sounds, smells, and turns his life a bit chaotic

To help your dog after moving, you may need to re-train them to pee outside.

You should supervise your dog as much as possible to prevent unwanted peeing in the house.
