What is Hematuria in Dogs?

Hematuria is the presence of red blood cells in the urine. It is a symptom rather than a stand-alone condition and can manifest in various forms. Sometimes the blood in the urine is visible, giving the urine a pink, red, or brownish hue. In other cases, the blood is microscopic, visible only under a microscope during lab tests. Regardless of the visibility, the presence of blood in your dog's urine is a symptom that warrants further investigation. It indicates that somewhere within the urinary tract or even in other systems of the body, something is not quite right.

The Causes of Blood in Dog Urine

Hematuria can result from a plethora of causes, which can be broadly categorized as non-infectious and infectious. Each cause may lead to hematuria in a different way, and identifying the root issue is essential for effective treatment. Below are some potential causes:

Infectious Causes:

Urinary Tract Infections (UTIs): One of the most common causes, urinary tract infections can result from bacteria infiltrating any part of the urinary system, including the kidneys, bladder, ureters, and urethra.

Bladder Infections: Similar to UTIs but localized in the bladder, these are also a frequent cause of hematuria.

Non-Infectious Causes:

Bladder Stones: These are mineral deposits that form in the bladder. Depending on their size and location, they can cause various degrees of irritation and bleeding in the bladder lining.

Kidney Stones: These are similar to bladder stones but form in the kidneys. While less common, they can be more serious and can cause blood to appear in the urine.

Trauma: Physical injuries to the lower urinary tract, such as from an accident or a fall, can lead to blood in the urine.

Poisoning: Toxic substances can wreak havoc on a dog's system, including causing internal bleeding that may manifest in the urine.

Systemic Diseases: Conditions such as diabetes, Cushing’s disease, and hemophilia can cause hematuria either directly or indirectly.

Genetic Predispositions: Some breeds are more prone to conditions that can cause hematuria, such as bladder stones or specific kinds of kidney disease.

Medications: Certain drugs can cause blood in the urine as a side effect.

What To Do If Your Dog is Peeing Blood

Noticing blood in your dog's urine can be a nerve-wracking experience, but swift action is essential. First and foremost, seek immediate veterinary consultation. Trying home remedies or waiting for the symptom to resolve on its own is not advisable, as it may worsen the underlying condition. Here's a step-by-step guide on what to do:

  1. Collect a Sample: If possible, collect a fresh urine sample from your dog using a clean, shallow container. This will be valuable for diagnostic tests.

  2. Note Symptoms: Take note of any other symptoms your dog may be experiencing, such as changes in appetite, lethargy, or frequent urination. This can help your veterinarian make a more accurate diagnosis.

  3. Seek Veterinary Consultation: With the urine sample and your observations in hand, consult your veterinarian as soon as possible for a thorough check-up and appropriate tests.

  4. Follow Treatment Plans: Once a diagnosis is made, adhere strictly to the treatment plan prescribed by your veterinarian.

Can I Prevent My Dog From Peeing Blood?

While it may be impossible to entirely eliminate the risk of hematuria in your dog, you can certainly reduce its likelihood by adopting a proactive approach to your pet's health. Here are some preventive measures that you can take:

1. Regular Veterinary Check-ups: Frequent veterinary visits for routine screenings

can help in the early identification of potential issues that could lead to hematuria.

Early intervention is always easier and often more effective than treating a

developed condition.

2. Proper Diet: Feeding your dog a balanced, nutritious diet that is appropriate for

their age, size, and health conditions can go a long way in preventing urinary issues,

including the formation of bladder and kidney stones.

3. Hydration: Ensure your dog has access to fresh and clean water at all times.

Adequate hydration can help prevent the concentration of minerals that may form

stones in the urinary system.

4. Exercise: Regular physical activity not only keeps your dog fit but also stimulates

frequent urination, which can help flush out any unwanted substances in the

urinary system.

5. Observation: Being aware of your dog's urination habits can help you catch any

abnormalities like frequent urination, straining, or discomfort, which are often

precursors to conditions leading to hematuria.

Is Blood in Dog Urine a Sign of Cancer?

Not necessarily. Blood in your dog's urine is certainly a cause for concern, but it's important to remember that it is not an automatic indicator of cancer. Far more common causes of hematuria are UTIs and bladder stones. However, in certain cases, the presence of blood in the urine could be a symptom of tumors within the urinary system or elsewhere.

Tumors in the bladder, kidneys, or along the urinary tract can cause bleeding that manifests as hematuria. Therefore, it is crucial to get an accurate diagnosis from your veterinarian, which usually involves a series of diagnostic tests to rule out or confirm malignancies.

How Hematuria is Diagnosed in Dogs

Diagnosing the cause of hematuria involves a multi-step approach that begins with a thorough physical examination and medical history, followed by various tests. The kind of tests administered often depends on your veterinarian's initial findings and suspicions. Some commonly used diagnostic methods include:


A laboratory analysis of the urine sample can provide clues about possible infections, crystals, or abnormal cells. This is often the first test performed and can be highly informative.

Blood Tests

Complete blood count and chemistry panels can give a broader view of your dog's overall health, revealing signs of systemic diseases or conditions that might be related to hematuria.


This non-invasive imaging technique allows your veterinarian to visualize the internal structures of the urinary system and can reveal stones, tumors, or other abnormalities.


While less detailed than ultrasounds, X-rays can be useful in detecting larger stones or skeletal issues that might be causing hematuria.


In more complicated or persistent cases, a cystoscope (a thin tube with a camera on the end) may be inserted into the urethra to inspect the bladder and other parts of the urinary tract directly.


If tumors are suspected, a biopsy may be conducted to determine whether they are benign or malignant.

Treatment Options For Hematuria in Dogs

The course of treatment for hematuria will depend on the diagnosis of the underlying cause. As hematuria itself is a symptom, treating the root issue is critical for resolution. Here are some of the most common treatment options based on different causes:

For Urinary Tract and Bladder Infections

Antibiotics: These are the first line of treatment for bacterial infections. The specific type and duration of antibiotic therapy will depend on the results of a urine culture and sensitivity test.

Anti-Inflammatory Medications: To manage inflammation and discomfort, your veterinarian may prescribe anti-inflammatory drugs.

For Bladder and Kidney Stones

Dietary Changes: A specialized diet may dissolve certain types of stones.

Surgical Removal: In cases where the stones are too large to pass or dissolve, surgical intervention may be necessary.

Laser Lithotripsy: This minimally invasive procedure uses lasers to break up stones into smaller, more easily passable pieces. VetMed specializes in performing laser lithotripsy.

For Trauma

Hospitalization and Monitoring: Severe physical trauma may require hospitalization for close monitoring and treatment of associated symptoms.

Surgery: In cases of significant injury, surgical repair may be necessary.

For Poisoning

Detoxification: Immediate intervention to remove the toxin is crucial, which may involve inducing vomiting, administering activated charcoal, or other treatments as appropriate.

For Systemic Diseases

Medication and Lifestyle Changes: Diseases like diabetes or Cushing's disease will require long-term medication and lifestyle adjustments, such as diet changes and possibly insulin therapy.

Regular Monitoring: Ongoing veterinary visits will be necessary to monitor the progress and adjust treatment as necessary.
