What are the Symptoms of Low Estrogen in Spayed Dogs?
The primary symptom of low estrogen in spayed dogs is urinary incontinence, often manifested as dribbling urine while sleeping or resting; however, other signs, though less common, can include changes to the vulva.
Understanding Estrogen’s Role in Spayed Dogs
Spaying, or ovariohysterectomy, removes the ovaries – the primary source of estrogen in female dogs. While this surgical procedure provides numerous health benefits, such as preventing uterine infections and tumors, it also eliminates estrogen production, potentially leading to estrogen-responsive urinary incontinence, also known as spay incontinence. Understanding the physiological role of estrogen is key to grasping why this occurs. Estrogen contributes to the maintenance of the tone and function of the urethral sphincter, the muscle responsible for controlling the flow of urine from the bladder. When estrogen levels decrease significantly after spaying, the sphincter can weaken, resulting in urine leakage. It’s crucial to remember that not all spayed dogs will develop this condition, and other factors can also contribute to urinary incontinence.
Symptoms of Low Estrogen: Recognizing the Signs
What are the symptoms of low estrogen in spayed dogs? The most common and noticeable sign is urinary incontinence, which often manifests in various ways:
- Dribbling Urine: This is the hallmark symptom. Owners might notice wet spots on the dog’s bedding or where she has been lying down. It often occurs when the dog is relaxed or asleep.
- Wet Hindquarters: Frequent urine leakage can lead to dampness and a noticeable urine odor around the hindquarters.
- Increased Urination Frequency: While not always directly linked to low estrogen, the feeling of incomplete bladder emptying can prompt more frequent trips outside.
- Urinary Tract Infections (UTIs): Due to residual urine increasing bacterial growth.
While urinary incontinence is the primary concern, other, less frequent, signs sometimes linked to low estrogen include:
- Changes to the Vulva: In some cases, a veterinarian might observe a recessed or underdeveloped vulva.
Diagnosis of Low Estrogen-Related Incontinence
Diagnosing low estrogen-related incontinence in spayed dogs usually involves a combination of:
- Physical Examination: The veterinarian will perform a thorough physical examination to rule out other potential causes of urinary incontinence, such as bladder stones, urinary tract infections, or neurological problems.
- Urinalysis and Urine Culture: These tests help to rule out urinary tract infections.
- Blood Tests: Blood tests can assess overall health and rule out other conditions affecting urinary function.
- Estrogen Trial: In some cases, a veterinarian might prescribe a short course of estrogen supplementation to see if the urinary incontinence improves. A positive response to estrogen often confirms the diagnosis.
- Urethral Pressure Profile: This test measures the pressure within the urethra and can help assess the strength of the urethral sphincter. It is not always readily available.
Treatment Options for Spay Incontinence
Several treatment options are available for managing urinary incontinence related to low estrogen in spayed dogs:
- Estrogen Replacement Therapy: This is the most common treatment. Medications like diethylstilbestrol (DES) or estriol (Incurin) are prescribed to supplement estrogen levels. The dosage is carefully monitored to minimize potential side effects.
- Alpha-Adrenergic Agonists: These medications, such as phenylpropanolamine (PPA), work by increasing the tone of the urethral sphincter. PPA is often used alone or in conjunction with estrogen.
- Combination Therapy: Some dogs benefit from a combination of both estrogen replacement therapy and alpha-adrenergic agonists.
- Surgery: In severe cases, surgical options may be considered to improve urethral sphincter function, although this is less common.
Choosing the appropriate treatment depends on the severity of the incontinence, the dog’s overall health, and the veterinarian’s recommendation.
Considerations and Potential Side Effects
While treatment for spay incontinence is generally safe and effective, it’s important to be aware of potential side effects:
- Estrogen Replacement Therapy: Side effects can include bone marrow suppression, especially with DES. Estriol is generally considered safer with fewer side effects.
- Alpha-Adrenergic Agonists: Side effects can include increased heart rate, restlessness, and high blood pressure.
Regular monitoring by a veterinarian is essential to ensure the treatment is effective and to minimize the risk of side effects.
Preventative Measures
There are no preventative measures to take as the removal of the ovaries is what causes the change.
What are the Symptoms of Low Estrogen in Spayed Dogs: Importance of Early Detection
Early detection and treatment are crucial for managing urinary incontinence in spayed dogs. If you notice any signs of urinary leakage, contact your veterinarian promptly. Early intervention can help prevent complications and improve your dog’s quality of life. The earlier you detect the issue, the better!

Frequently Asked Questions (FAQs)
What other conditions can cause urinary incontinence in spayed dogs?
- Besides low estrogen, other causes of urinary incontinence in spayed dogs include urinary tract infections, bladder stones, anatomical abnormalities, neurological disorders, and certain medications. A thorough veterinary examination is crucial to determine the underlying cause.
Is urinary incontinence a common problem in spayed dogs?
- While it doesn’t affect every spayed dog, urinary incontinence is a relatively common issue, affecting an estimated 5-20% of spayed female dogs, depending on breed and size.
Can urinary incontinence be cured in spayed dogs?
- In many cases, urinary incontinence can be effectively managed with medication, although a complete cure isn’t always possible. Treatment often requires lifelong management.
Are certain breeds more prone to developing urinary incontinence after spaying?
- Yes, certain breeds, such as Irish Setters, Doberman Pinschers, Old English Sheepdogs, and Rottweilers, appear to be more predisposed to developing urinary incontinence after spaying. Larger breeds are also thought to be more susceptible.
How long does it take for treatment to work for urinary incontinence?
- The time it takes for treatment to become effective can vary. Some dogs respond within a few days of starting medication, while others may take several weeks to show improvement.
What should I do if my dog is still incontinent despite treatment?
- If your dog remains incontinent despite treatment, your veterinarian may need to adjust the dosage or switch to a different medication. Further diagnostic testing might also be necessary to rule out other underlying causes.
Are there any natural remedies for urinary incontinence in spayed dogs?
- While some owners explore natural remedies, there is limited scientific evidence to support their effectiveness for treating estrogen-related incontinence. It’s important to consult with your veterinarian before trying any alternative therapies.
What is the prognosis for dogs with urinary incontinence?
- The prognosis for dogs with urinary incontinence is generally good with proper management. Most dogs can live a normal, happy life with medication to control their symptoms.
How is estriol different from DES?
- Estriol is a weaker form of estrogen compared to DES (diethylstilbestrol), and it’s generally considered safer with a lower risk of bone marrow suppression. It is often the preferred choice for treating spay incontinence.
Can diet affect urinary incontinence in spayed dogs?
- While diet isn’t a direct cause of urinary incontinence, maintaining a healthy weight can help reduce pressure on the bladder. Some veterinarians also recommend diets that promote urinary health.
What are the long-term effects of using estrogen replacement therapy in spayed dogs?
