Hematuria in Dogs: Urgent Guide to Causes, Warning Signs & Life-Saving Treatment

Noticing hematuria in dogs—or blood in your dog’s urine—can be alarming. This guide explores the possible causes, from simple infections to more serious conditions, as well as how to recognize symptoms and pursue effective treatment. Acting quickly can make all the difference in your dog’s health.

When you notice blood in your dog’s urine, it can be a cause for concern. Hematuria, the medical term for blood in the urine, is often an indication that something is amiss with your pet’s urinary system. While hematuria is commonly associated with inflammation or infection in the urinary tract, there are various underlying causes that can only be identified through a thorough examination by a veterinarian. In this comprehensive guide, we will explore the causes, symptoms, diagnosis, and treatment options for hematuria in dogs, providing you with the knowledge and understanding you need to ensure your dog’s wellbeing.

Understanding Hematuria

What is Hematuria?

Hematuria refers to the presence of blood in the urine. It can manifest as visible blood, giving the urine a reddish appearance, or it may only be detectable through laboratory analysis. In some cases, blood clots may also be observed in the urine. It is important to note that hematuria itself is not a disease but rather a symptom of an underlying condition affecting the urinary system.

Clinical Signs of Hematuria

In addition to the presence of blood in the urine, dogs with hematuria may exhibit other clinical signs. These can include straining to urinate, frequent urination in small amounts, and in male dogs, straining to defecate due to an enlarged prostate. It is crucial to monitor your dog’s urination habits and seek veterinary attention if you notice any abnormalities.

Causes of Hematuria

The causes of hematuria in dogs can be classified into two main categories: lower urinary tract bleeding and upper urinary tract bleeding. Let’s explore each of these categories in detail.

Lower Urinary Tract Bleeding

When the lower urinary tract is involved, additional clinical signs of cystitis, inflammation of the bladder wall, are typically present. The following are some common causes of lower urinary tract bleeding:

1. Bladder Issues: Inflammation of the bladder wall, known as cystitis, can lead to bleeding. This can be caused by uroliths (bladder stones), polyps (benign growths), infections, or, in cats, feline lower urinary tract disease (FLUTD), which is associated with stress and anxiety.
2. Prostate Problems: Unneutered male dogs may experience bleeding from the prostate due to prostatitis (infection) or benign hyperplasia (enlargement) caused by testosterone stimulation. In neutered dogs, prostate cancer should be considered.
3. Vaginal/Urethral Issues: Infections, sterile inflammations, and polyps in the vaginal area can cause blood in the urine.

Upper Urinary Tract Bleeding

In cases of upper urinary tract bleeding, there are usually no signs of discomfort during urination. The following are potential causes of upper urinary tract bleeding:

1. Kidney Problems: Infections, nephroliths (stones), and occasionally benign or malignant tumors can cause bleeding from the kidneys. Idiopathic renal hemorrhage, where the cause of the bleeding cannot be identified, is also possible.
2. Other Causes: While less common, bleeding in the upper urinary tract can also be attributed to issues such as trauma, infectious diseases, diabetes, coagulation disorders, and vasculitis (blood vessel inflammation).

Diagnosing Hematuria

If you suspect your dog has hematuria, it is important to schedule a veterinary appointment for a proper diagnosis. During the consultation, the veterinarian will conduct a thorough examination and may recommend the following tests:

1. Urinalysis: A urinalysis helps evaluate the characteristics of the urine, such as the presence of red blood cells (RBCs), white blood cells (WBCs), bacteria, and other substances. It can provide valuable insights into the possible cause of the hematuria and help guide further diagnostic steps.
2. Imaging Techniques: Ultrasound scans are commonly performed to assess the structure of the urinary tract and identify any abnormalities. Contrast radiographs or cystoscopy may also be recommended in certain cases to obtain more detailed information.
3. Additional Tests: Depending on the findings from the initial tests, the veterinarian may suggest further investigations, such as blood tests, biopsies, or specialized imaging procedures, to determine the underlying cause of the hematuria.

Treatment Options

The treatment for hematuria in dogs depends on the underlying cause. Once the cause has been identified, appropriate measures can be taken to address the specific condition. Here are some possible treatment options:

1. Antibiotics: If a urinary tract infection is detected, antibiotics will be prescribed to eliminate the infection and reduce inflammation.
2. Surgery: In cases of bladder stones, tumors, or other structural abnormalities, surgical intervention may be necessary to remove the source of bleeding.
3. Medications: Depending on the diagnosis, your veterinarian may prescribe medications to manage the underlying condition, alleviate discomfort, and promote healing.
4. Dietary Adjustments: In some cases, dietary changes, such as switching to a special urinary health diet, may be recommended to prevent recurrent urinary issues.
5. Ongoing Monitoring: Regular check-ups and monitoring of your dog’s urinary habits are essential to detect any changes or recurrence of hematuria. Your veterinarian may recommend follow-up tests to ensure the effectiveness of the treatment.

When to Seek Veterinary Care

It is important to promptly seek veterinary care if you observe blood in your dog’s urine or notice any other concerning symptoms. Early detection and intervention can significantly improve the outcome for your dog. Contact your veterinarian if you observe the following:

• Blood in the urine
• Frequent urination
• Straining to urinate
• Discomfort or pain during urination
• Changes in urination habits

Conclusion

Hematuria in dogs can be an alarming sign of an underlying issue within the urinary system. It is essential to consult with a veterinarian to determine the cause of the hematuria and develop an appropriate treatment plan. By closely monitoring your dog’s urinary habits and seeking prompt veterinary care when necessary, you can ensure the health and wellbeing of your beloved pet.
