About Dog Incontinence

Dog incontinence is fairly common, and can happen to any dog - regardless of age or sex.

If your pet is incontinent it means that she is unable to control her bladder and/or bowels.

Most of the time it's her urine that she'll have difficulty with, it's pretty rare for bowel movements to be a problem. 

Sometimes her loss of control will be a one-off episode, other times it's a chronic problem, but it is always uncomfortable and messy, and often worrying too.

Incontinence shouldn't be confused with puppy potty training  'accidents'. Young puppies haven't developed bladder or bowel control and need time to mature and learn, but it takes time! 

Before you can decide on the best way to help your dog, you need to know why she/he is having trouble in the first place.

Although female dogs are more likely to have this issue, male dogs can too.

Older dogs are also higher-risk for incontinence issues, but it can happen with puppies and dogs of all ages.




What Causes Incontinence In Dogs?

There are several different reasons why a dog can have difficulty controlling their urinary function.

Here are the most common ones (click on links to jump to relevant section):

Dr Megan Teiber, DVM, has written about incontinence in dogs from a veterinary perspective exclusively for this website. You can CLICK HERE to read her article, or simply scroll to the bottom of the page to read it.


Urinary Tract Infection

This is very common, especially in females and in puppies, but can affect either sex.

Caused by bacteria which enters the urethra and then multiplies and spreads inwards. Untreated it could reach the kidneys and cause serious problems.

Often a UTI (also known as as a bladder infection or  Cystitis) can occur when a pup's (or dog's) immune system is weakened, either by stress or illness.

This may be one of the reasons it's common in young puppies who have just left their momma and littermates, are also getting vaccinations, and are stressed by change.

A female pup gets much lower to the ground when peeing than a male pup usually does (making it easier for her urinary system to exposed to bacteria), plus her urethra is shorter than that of a male which means bacteria can travel to her bladder quickly.

Other conditions can cause recurring infections, these include bladder stones, an incorrect acid/alkali balance in the bladder, or a defect in the ureter or vulva. Diabetes or Cushing's Disease can also cause incontinence in dogs.

Or conditions such as tumors, bladder stones, prostate disease and more.

Occasionally a urinary stone or tumor blocks which has caused problems will suddenly completely block the ureter and your dog won't be able to pee at all. 

This is a veterinary emergency as if it's not treated quickly your pet could die.

Symptoms of a UTI don't usually involve a flood or urine.

Your pup/dog is likely to have an urgent need to pee MUCH more often than normal, and sometimes she may only be able to squeeze out a drop or two.

Her urine may be cloudy or bloody and/or have a strong odor, and there's often a lot of licking at her privates and possibly some discharge.

Spay Surgery

This is the most common cause of 'leaky plumbing' in female dogs.

In this case the poor urinary control is usually due to the fluctuation in hormone levels which happens as a result of the procedure, but occasionally there can also be physical problems.

This is often called 'hormone-responsive incontinence'.

Various studies have come up with different figures in terms of the percentage of dogs who have incontinence issues after being spayed.

In 2009 one study suggested around 20% were affected, another survey in 2013 puts the figure at 5%.

My consultant, Dr. Megan Teiber, DVM, told me that she personally believes that many dogs with this type of urinary incontinence suffer so mildly or infrequently that many owners don't seek veterinary care.

I've owned many dogs over my lifetime, and am surrounded by dog-owning family and friends. I have not personally had a dog who had a problem with this after being spayed, nor do I know anyone who has.

Hormone responsive incontinence in dogs often appears as a loss of control during sleep, which ends in Fifi wetting her bed.

But it could show as an inability to hold her pee for long, or as a constant/intermittent dribble of urine.

Some breeds are at higher risk of developing this problem than others. These include German Shepherds, Boxers, Doberman Pinschers, Old English Sheepdogs, Rottweilers, Weimeraners, Irish Setters and some Spaniels.

Also larger breeds are more prone to this problem, as are dogs who have their tails docked as puppies

* This can sometimes (but not often) happen in neutered male dogs too.

Defects In The Urinary Tract

Physical malformations of any part of the urinary tract will usually mean that things don't work quite the way they should.

The most common defect in female dogs is a birth defect called an 'Ectopic Ureter'. 

The ureter is a tiny tube down which urine flows from the kidneys to the bladder. 

When a pup has an ectopic ureter, the tube bypasses the bladder and carries urine directly to the urethra (or sometimes to the vagina) instead, so there's no 'holding cell' as it were and the urine comes flows out unimpeded.

Ectopic Ureter is a hereditary condition and some breeds are more prone to it that others.

These include Labrador Retrievers, Siberian Huskies, Welsh Corgis, Collies, West Highland Terriers, Wire-haired Fox Terriers and Miniature Poodles.

Symptoms can include an almost continuous dribble of urine, or flooding/bed-wetting. Irritation and inflammation around the vulva is often seen too.

Neurological or Spinal Problems or Seizures

Neurological problems (to do with the nervous system) can interfere with the way your dog's urinary tract functions. Affects both males and females.

Spinal injuries or diseases (such as a spinal disc problem seen in long-bodied dogs like Dachshunds) or tumors can have the same effect.

Brain tumors or brain injury or disease can do the same thing.

Basically the disease or damage interferes with the signals sent by the brain and incontinence can be one of the resulting problems.

If your dog has a seizure he'll lose control of his muscles and nervous system. This includes his bladder and bowels. 

When not in the grips of a seizure, your dog's bladder control will be normal.

Canine Cognitive Dysfunction (aka 'Doggy Alzheimers') can sometimes cause an old dog to 'forget' their house-training skills or simply how to control their bodily functions.

Illness, Disease & Syndromes

Sometimes a dog's leaky bladder is a symptom of another underlying condition.

These could include diabetes, kidney disease, liver disease, Addison's disease and Cushing's disease.

Symptoms will vary depending on what's causing the problem. 

In that situation you need to treat the main disease or problem which should then relieve the symptoms, including incontinence.

Most diseases and problems affect both male and female dogs pretty equally.

Some medications (such as sedatives) can cause temporary incontinence, as can the lingering effects of anesthetic or strong pain-killers post-surgery.

Stress & Anxiety

You know the expression 'I was so scared I almost wet myself'? Well, in some cases dogs actually do wet themselves!

The most common type of incontinence in this category is submissive urination. This is an involuntary behavior and causes him/her to pee as a sign of submission.

Scared Chihuahua

It's most often seen in puppies who are very gentle, or anxious. Affects males and females but tends to be seen slightly more often in females.

Separation anxiety is another emotional cause for loss of bladder control, often bowel control as well. 

If your puppy or dog gets so anxious when you leave him that he becomes hysterical he may pee and/or poop uncontrollably.

This is not a gender-specific problem, boys are as likely to suffer as girls.

Old Age

As your dog gets older, his/her bladder control may well get less efficient. This is usually due to a 'weak bladder sphincter'.

Sometimes it can be a delayed reaction to spay surgery, or the result of the diseases of old age such as kidney failure.

Other times it's simply part of the aging process, the overall weakening of muscles and the deterioration of bodily functions.

Senior dog with owner

 Canine Cognitive Dysfunction (the dog version of Altzheimer's Disease) can lead to a senior dog forgetting where they're supposed to eliminate, or when.

Hormone-related or spay incontinence affects females, but old age gets to all dogs regardless of gender.

If there is a specific medical cause for your older dog's weak bladder then by treating the root of the problem you will also improve the leaking.

But sometimes it's just a case of managing the problem and minimizing the discomfort for your dog and disruption for you.

Dog Incontinence - A Veterinarians' View

Urinary incontinence is not terribly uncommon in dogs, but can be very frustrating for pet parents!

There are several causes for incontinence, and providing a detailed history of your dog’s behavior will help your vet make a diagnosis.

First, it’s important to define what incontinence is and what it isn’t.  Dogs with incontinence will leak urine without any conscious effort to urinate.  They won’t “assume the position” to urinate and they don’t always notice when it happens. 

Typically your dog will be lying down or sleeping, and when she gets up she leaves a puddle of urine behind.  Urinating more frequently, straining to urinate, or having accidents in the house with conscious control are all signs of a urinary tract problem, but are not incontinence.   

If you suspect incontinence, try to determine when and how often it happens, how much urine she leaks, and how much water she is drinking.   Determine if she is still urinating normally when she goes outside on walks.  This information will help your vet make appropriate recommendations for testing and treatment options. 

The primary medical causes of incontinence are:

  • Urethral sphincter mechanism incontinence (spay incontinence)
  • Urinary tract inflammation
  • Overflow incontinence
  • Neurologic disease

Sphincter mechanism incontinence occurs in spayed female dogs due to hormonal imbalances.  The muscle that keeps urine in the bladder is too relaxed.  Dogs may leak very sporadically or on a daily basis. The urine itself is normal.  Spay incontinence doesn’t actually pose much of health risk to the dog, but is unsanitary and a nuisance for owners.  If your dog continues to urinate appropriately while outside, and urine analysis and culture tests are normal, she likely has this type of incontinence. Most dogs will respond to one or more daily medications to increase sphincter control. 

Dogs with urinary tract inflammation (cystitis), can also have incontinence.  Bacterial infections, bladder stones, and bladder tumors all cause inflammation.  Usually dogs with cystitis have signs of discomfort including straining to urinate, blood in the urine, or an urge to go frequently.  Incontinence is rarely the only symptom for cystitis, but it can happen.

Urine tests will detect blood, inflammatory cells, crystals, or bacteria.  Urine cultures will confirm bacterial infection and bladder x-rays diagnose bladder stones.  Once these conditions are treated appropriately, incontinence should resolve.   Urinary infection is much more prevalent in female dogs, but is possible in male dogs as well. 

Overflow incontinence is secondary to diseases that cause your dog to produce more urine.  The bladder leaks simply because it is too full.  Common examples include diabetes, kidney disease, and Cushing’s disease (overactive adrenal gland), but there are many others. In these cases the urine concentration (called the specific gravity) is very dilute.

If you notice that your dog is drinking more water and asking to go outside frequently in addition to incontinence, your vet will recommend bloodwork in addition to urine testing. 

Bloodwork will measure glucose, electrolytes, kidney values, and liver enzymes. It serves as a guide for further testing recommendations.  Incontinence should improve when the underlying disease is properly controlled.

Disorders that inhibit nerve function to the hind end are a less common cause of incontinence.  Usually these dogs will have other neurologic problems, such as discoordination or paralysis in their back legs.  

Young puppies that are leaking urine should be investigated for ectopic ureters.  Usually the incontinence is extremely frequent and house training is difficult.  Thankfully this condition is rare, but requires advanced imaging techniques to diagnose. 

Very elderly dogs who develop incontinence likely have some combination of these factors present, in addition to cognitive (senility) delays.  

Due to anatomical differences, it is very rare for male dogs to develop incontinence.  However, it can also be much more difficult to diagnose and treat.  If your male dog is leaking urine, your vet will need to perform a very thorough diagnostic workup to get to the root of the problem. 

Thankfully, fecal incontinence is very rare compared to urinary incontinence.  It is usually seen as a result of severe neurologic disease, tails docked too short, or in very elderly dogs.

REMEMBER: Whatever the reason for your dogs leaky pipes, there's something you can do to help her feel better and minimize the mess and disruption.

Good luck to you both.
