Older female dog incontinence can be a challenging issue for many pet owners. It's estimated that up to 20% of dogs over the age of 10 experience incontinence.
This age-related decline in bladder control can be caused by a variety of factors, including hormonal changes, weakened pelvic muscles, and age-related kidney disease. These factors can lead to a decrease in the dog's ability to hold their urine.
As dogs age, their hormone levels change, which can lead to a decrease in estrogen levels in females. This decrease can cause the muscles in the bladder and urethra to weaken, resulting in incontinence.

What Is Incontinence?
Incontinence in older female dogs is a frustrating and embarrassing issue for many pet owners. It's the involuntary leaking of urine, meaning your dog can't fully control her bladder.
This can range from small drops of urine to complete emptying when moving around or even while resting or sleeping. It's not uncommon for incontinent dogs to leak urine in their bed or on the couch.
Incontinence is not the same as having an accident in the house, where the dog is aware of what's happening. With incontinence, the dog is often "taken by surprise" by her damp hind end.

Causes of Incontinence
Urinary incontinence in older female dogs is a common issue that can be caused by a combination of factors. One of the main causes is Urethral Sphincter Mechanism Incompetence (USMI), which affects approximately 80% of older dogs with urinary incontinence. USMI is the failure of the "valve" of the bladder neck and urethra to prevent urine leakage, often occurring along with ectopic ureters.
Hormone Responsive Urinary Incontinence is another common cause, related to the decrease in estrogen levels after spaying. This decrease in estrogen can lead to a female dog's inability to close their urinary sphincter fully, resulting in leaking. Bladder Storage Dysfunction, where the bladder contracts too frequently, can also contribute to incontinence.
Here are some possible causes of urinary incontinence in older female dogs:
- Urethral Sphincter Mechanism Incompetence (USMI)
- Hormone Responsive Urinary Incontinence
- Bladder Storage Dysfunction
- Ectopic ureters
Note: These causes can be interrelated, and a combination of factors may be contributing to the incontinence. It's essential to consult with a veterinarian to determine the underlying cause and develop an effective treatment plan.
What Causes Incontinence?
Urinary incontinence in dogs can be caused by a variety of factors, including underlying health problems and behavioral issues.
Medical conditions such as urinary tract infections, uroliths, and spinal cord disease can lead to incontinence in dogs. Excessive drinking of water, often caused by diabetes mellitus or kidney failure, can also contribute to incontinence.
Dogs with separation anxiety or noise phobias may exhibit incontinence due to stress and anxiety. A strong urine odor and skin irritation around the genitals are common symptoms of urinary incontinence.
Urinary incontinence can be caused by a range of factors, including anatomical abnormalities, urethral sphincter mechanism incompetence, hormone-responsive incontinence, and neurological causes.
Here are some possible causes of urinary incontinence in dogs:
- Anatomical abnormalities, such as ectopic ureters, can cause urine leakage.
- Urethral Sphincter Mechanism Incompetence (USMI) is a common cause of incontinence in older dogs.
- Hormone-responsive incontinence can occur in spayed female dogs due to decreased estrogen levels.
- Neurological causes, such as spinal cord disease or lesions, can disrupt the nerves controlling the bladder.
In some cases, incontinence can be caused by a combination of factors, such as a weak bladder sphincter and a urinary tract infection.
Stress
Stress can be a major contributor to incontinence in dogs, especially those that are fearful or anxious by nature.
A new environment can be overwhelming for a dog, leading to stress and incontinence. Loud noises can also cause a dog to become stressed and leak urine.
Strangers can be a source of stress for some dogs, causing them to lose bladder control. Changes at home, such as a new pet or person, can also cause a dog to feel stressed and incontinent.
Dogs may become stressed for many reasons, including the presence of another more intimidating dog. Fearful dogs are particularly prone to peeing under stress, making it essential to identify and address the underlying causes of their fear.
Diagnosing and Treating Incontinence
Diagnosing incontinence in older female dogs requires a thorough examination by a veterinarian. They will perform a physical exam and take a complete medical history to understand the dog's overall health and identify any potential underlying causes.
Blood tests can help identify kidney function, hormonal imbalances, and electrolyte abnormalities that may be contributing to incontinence. Your veterinarian may also ask you to bring a sample of your dog's urine to the appointment.
Diagnostic tests such as urinalysis, ultrasound, urine culture, and radiography (X-rays) can help determine the underlying cause of incontinence. These tests can identify issues such as bladder infections, kidney stones, or weakened bladder muscles.
If your veterinarian diagnoses a urinary tract infection (UTI), they may prescribe antibiotics such as amoxicillin, sulfamethoxazole, or tetracycline to treat the infection. Pain medications may also be prescribed to help manage pain caused by the infection.
Here are some common treatments for specific conditions that may be contributing to incontinence in older female dogs:
- Urinary Tract Infections (UTI): antibiotics such as amoxicillin, sulfamethoxazole, and tetracycline
- Bladder Stones: diet and medications like allopurinol, or surgical intervention
- Weak Bladder: hormone replacement medications or drugs like phenylpropanolamine, or surgery
Veterinarian Diagnosis Process
Your veterinarian will perform a series of diagnostic tests to determine the underlying cause of your dog's incontinence.
A medical history and physical exam are essential in understanding your dog's overall health and identifying any potential underlying conditions.
Your vet may ask you to bring a sample of your dog's urine to the appointment, so it's a good idea to learn how to collect a clean urine sample to make the process smoother.

Diagnostic tests may include urinalysis, blood tests, ultrasound, urine culture, and radiography (X-rays).
These tests can help identify incontinence and underlying conditions such as kidney function issues, hormonal imbalances, bladder infections, and electrolyte abnormalities.
Here are some common diagnostic tests used to diagnose urinary incontinence in dogs:
- Urinalysis
- Blood tests
- Ultrasound
- Urine culture
- Radiography (X-rays)
A urine culture can help identify bladder infections, which are common in dogs with urinary incontinence and can cause complications if not diagnosed and treated.
Treating
Treating incontinence in dogs requires a thorough understanding of the underlying cause. Medications are a common treatment option, with drugs like phenylpropanolamine (PPA) being frequently used to strengthen bladder muscles.
Your veterinarian can prescribe medications in different doses until an effective combination is found. Phenylpropanolamine is well-tolerated by many dogs, but pet parents should monitor their dogs closely due to potential risks and side effects.
Hormone therapy can be beneficial for spayed female dogs, while testosterone injections may be necessary for males. However, these treatments can affect bone marrow, requiring frequent blood work.
Dog diapers can be a helpful tool for managing cleanliness, but it's essential to monitor for signs of urine scalding or skin infection.
Here are some common treatments for specific conditions:
Surgical therapy can be considered if dogs don't respond to medical therapy, and options include colposuspension, injection of bulking agents, or stem cell therapy.
Health Issues
Urinary incontinence in older female dogs can be caused by a weak bladder sphincter, a condition known as urethral sphincter mechanism incompetence (USMI). This is the most common cause of urinary incontinence in spayed female dogs, often starting in middle age.
Dogs weighing 15 kilograms (33 pounds) or more are seven times more likely to develop urinary incontinence. Several breeds are also more prone to this condition, including Bearded Collies, Boxers, and German Shepherd Dogs.
Some possible health issues that can lead to urinary incontinence in older female dogs include abnormal bladder positioning, estrogen deficiency or decline, obesity, genetics, or changes to vaginal support structures. Estrogen-responsive urinary incontinence is also a common issue, caused by decreased estrogen levels after spaying or as intact dogs age.
Here are some possible underlying health issues that can lead to urinary incontinence in older female dogs:
- Urinary tract tumors, such as cancers affecting the bladder, prostate gland, or urethra
- Neurological conditions, such as Canine Cognitive Dysfunction
- Diabetes and Cushing's Disease
- Urinary tract infections (UTIs)
- Bladder stones
- Ectopic ureters
- Weak bladder
UTI Types
UTIs in dogs can be caused by a variety of factors, including bacterial infections, and are commonly treated with antibiotics such as amoxicillin, sulfamethoxazole, and tetracycline.
In some cases, UTIs can be painful, so veterinarians often prescribe pain medications to help manage the discomfort.
Dogs with UTIs may exhibit symptoms such as frequent urination, leaking, and indoor accidents.
In fact, urinating in the house is a classic sign of a UTI in dogs, and it's a condition that's very treatable if caught early.
However, if left undetected, UTIs can be very serious and even life-threatening.
Here are some common types of UTIs in dogs:
It's worth noting that incontinent dogs are more prone to developing UTIs, especially if they have a shorter urethra, like female dogs.
By understanding the different types of UTIs, you can work with your veterinarian to develop a treatment plan that's tailored to your dog's specific needs.

Neurological Issues
Neurological Issues can cause dog incontinence. Spinal cord injuries can lead to permanent urinary and fecal incontinence.
Certain neurological conditions affect the spinal cord and surrounding nerves, causing dog incontinence. These conditions can be severe and impact a dog's quality of life.
A severe spinal cord injury can damage nerves that control the bladder and bowel. This can result in incontinence, as the dog may not be able to fully empty its bladder.
Fibrocartilaginous embolism, or FCE, is a rare condition where a piece of cartilage blocks blood flow in the spine. This can cause a stroke-like situation in dogs, but with dedication and physical therapy, they can recover over time.
Neurological conditions can also affect the bladder and sphincter, leading to incontinence in dogs. The nerves that control these functions must be working properly for a dog to be continent.
Tumors
Tumors can be a serious health issue in dogs, causing frequent urination and incontinence.
Urinary tract tumors, which affect the kidneys, ureters, bladder, prostate gland in males, and urethra, are a common cause of these symptoms.
Some tumors may require veterinary surgery to remove cancerous growths or repair structural issues and genetic defects.
In severe cases, surgery may be necessary to alleviate the symptoms and improve the dog's quality of life.

Medication Side Effects
Medication Side Effects can be a surprising cause of urinary incontinence in dogs. Some prescribed medications can make it harder for them to control their bladder muscles, leading to leaking and incontinence.
Certain medications can increase thirst in dogs, leading to more frequent urination and leakage. Prednisone, a cortisone derivative, and furosemide, a diuretic, are two commonly prescribed drugs that can lead to this issue.
Dogs taking seizure medications or certain pain medications may also experience urinary incontinence as a side effect. It's essential to discuss your dog's medication list with your vet to determine if there's a correlation between incontinence and medication.
Prednisone is particularly notorious for causing housebreaking accidents in dogs due to its side effects, which include dramatically increased thirst and a fuller bladder.

Thyroid and Metabolic Diseases
Thyroid and Metabolic Diseases are serious health issues that can affect your furry friend. Dog incontinence can be one symptom of thyroid disease or other diseases related to a dog's metabolism.
Thyroid disease is a common issue in dogs, and it's essential to recognize the signs. A dog's weight, appetite, and energy levels can all be affected by thyroid disease.
Some breeds are more prone to thyroid disease than others, and it's crucial to be aware of these breeds if you're a dog owner. The breeds at higher risk include Golden Retrievers, Doberman Pinschers, and Cocker Spaniels.
If you suspect your dog has a thyroid issue, it's vital to consult with a veterinarian as soon as possible. Regular check-ups and blood tests can help diagnose thyroid disease early on.
Early detection and treatment are key to managing thyroid disease in dogs. With the right care and attention, dogs with thyroid disease can lead happy and healthy lives.
Estrogen Deficiency
Especially for older, spayed female dogs, a lack of estrogen (hormonal imbalance) may result in incontinence.
For these dogs, hormonal therapy may be prescribed to alleviate symptoms.
An enlarged prostate or prostate disease may cause difficulty urinating or urinary incontinence in male dogs.
This can be a serious issue, especially if left untreated, as it can lead to further complications.
In older, spayed female dogs, a lack of estrogen can also cause other health issues beyond incontinence.
Female Dog Incontinence
Female dogs are more prone to urinary incontinence, especially after spaying surgery, which can disrupt hormone levels and weaken urethral muscles.
Spayed female dogs are more likely to experience urinary incontinence, particularly in their middle years, due to lower levels of estrogen and progesterone.
As a result, spayed female dogs may leak urine while sleeping or resting, which is often a sign of an underlying issue, such as age-related incontinence or a urinary tract infection.
Older
As dogs age, their muscles weaken, including the muscles of the bladder, making it more common for older dogs to experience urinary incontinence.
Age-related incontinence is a common issue in older dogs, and it's essential to note that this can happen to dogs of any breed or size.
If this caught your attention, see: At What Age Can a Female Dog Be Spayed
Older dogs may have mobility issues that impact their ability to get outside in time, which can lead to accidents in the house.
Dogs with genuine urinary or urethral incontinence often pee while resting or sleeping with no obvious triggers, and this can be a sign of an underlying health issue.
In older dogs, the muscles around the bladder weaken, making it more difficult for them to control their urine.
This weakening of the muscles can be due to the natural aging process, and it's not uncommon for older dogs to experience some level of incontinence.

Female
Female dogs are more prone to urinary incontinence due to lower levels of estrogen after spay surgery. This can lead to weakened urethral muscles.
As a result, female dogs may experience incontinence, especially when the muscles that keep urine in the bladder relax while they sleep. This is a common issue in middle-aged spayed female dogs.
Some female dog breeds are more susceptible to incontinence, but the exact causes can vary. Breeds like English Sheepdogs, Cocker Spaniels, and German Shepherds are more prone to urinary incontinence.
In fact, spayed female dogs are more likely to experience urinary incontinence than unspayed females. This is because estrogen and progesterone play a crucial role in strengthening the muscles that keep urine in the bladder.
Here are some breeds more prone to urinary incontinence:
- English Sheepdogs
- Cocker Spaniels
- German Shepherds
- Rottweilers
- English Springer Spaniels
- Doberman Pinschers
- Weimaraners
- Bulldogs
- Dalmatians
- Bearded Collies
- Collies
- Boxers
Veterinary Care and Expectations
When your older female dog visits the vet for incontinence issues, you can expect a thorough examination from nose to tail. Your veterinarian will perform a physical exam to assess your dog's overall health.
During the appointment, your veterinarian may run various tests to determine the underlying cause of your dog's incontinence. These tests include blood work, such as a CBC to check red blood cell count and white blood cell counts.
A biochemistry panel may also be run to look at kidney values, liver enzymes, proteins, blood sugar, and electrolytes. Your veterinarian may also check your dog's blood pressure to look for signs of certain diseases, including kidney disease.

Urinalysis and urine culture tests will be performed to check for bacteria in the urine, which is the gold standard diagnosis for UTIs. Your veterinarian may also use X-rays and/or ultrasound to look for bladder stones or masses, and to evaluate for arthritis or back injuries.
Specialized blood work may be done to rule out certain diseases such as Cushing's disease or thyroid disease. These tests help your veterinarian assess the health of your dog's organ systems, including the urinary system.
Your veterinarian is your teammate in caring for your dog's health, so don't hesitate to ask questions or seek their advice. As your dog's biggest advocate, you know her best, so be sure to share your observations with your veterinarian.
