Hematuria in Dogs: Causes, Symptoms & Treatment Tips

Hematuria in dogs means there is blood in their urine, which often signals an underlying health concern requiring prompt attention from a veterinarian. This condition can manifest as urine that’s visibly red or discolored, or it may be detected only through microscopic laboratory analysis. Being aware of the causes and symptoms helps American pet owners ensure their dogs receive timely veterinary care.

What Is Hematuria in Dogs?

Hematuria indicates bleeding somewhere along the urinary tract — including the kidneys, ureters, bladder, urethra, and, in male dogs, the prostate gland. The blood may be plainly visible or only detectable under microscopic evaluation. Both male and female dogs can experience hematuria, though females are particularly susceptible to urinary tract infections (UTIs), a common root cause in the U.S. Older dogs may develop cancers or tumors, while younger dogs might exhibit hereditary or genetic conditions linked to blood in the urine.

Recognizing Key Signs and Symptoms

The most apparent sign of hematuria is red or blood-tinged urine. Dogs might strain or show discomfort when urinating. Additional symptoms can include:

• Pain or tenderness in the abdomen upon gentle palpation
• Frequent urges to urinate but passing small amounts
• Lethargy or general weakness if a systemic illness is involved
• Visible blood clots or reddish discoloration in the urine
• Bruising beneath the skin if clotting disorders are present

Seven Common Causes of Blood in Dog Urine

Hematuria can arise from a variety of underlying problems. Leading causes observed by U.S. veterinarians include:

1. Urinary Tract Infection (UTI): The most common cause, especially in female dogs, where bacterial infections irritate the bladder lining resulting in bleeding.
2. Bladder Stones: Mineral formations (uroliths) that damage urinary tract tissues, causing blood to appear in urine. Treatment depends on the type and size of stones.
3. Kidney Disease: This includes infections, inherited kidney disorders, or tumors affecting kidney function.
4. Prostate Disease (male dogs): Prostate enlargement, infections, or cancers can lead to hematuria.
5. Blood Clotting Disorders: Conditions such as thrombocytopenia that cause abnormal bleeding, including in the urinary tract.
6. Trauma: Injury to any part of the urinary system from accidents, rough play, or external wounds.
7. Neoplasia (Cancer): Tumors in the urinary tract or associated organs often cause visible bleeding.

Veterinarian Diagnostic Process

An American veterinarian will first gather a detailed history including symptom onset and any previous health issues. The exam focuses on the abdomen, urinary tract, and prostate in males. Typical diagnostic tests include:

• Complete blood count (CBC) and serum chemistry profiles to assess organ function and clotting ability
• Urinalysis, including sediment examination to identify blood, infection, crystals, or abnormal cells
• Imaging methods like ultrasound and abdominal X-rays to detect stones, tumors, or anatomical abnormalities
• Biopsies or cystoscopy to obtain tissue samples when needed
• In male dogs, examination of prostate fluid or ejaculate samples if prostate disease is suspected

Treatment Options Customized by Cause

Therapy depends entirely on the underlying diagnosis. Common treatments provided by U.S. veterinarians include:

• Antibiotic courses tailored to bacterial infections based on sensitivity testing
• Diet changes or surgical removal for bladder stones that can’t be medically dissolved
• Supportive care such as intravenous fluids, hospitalization, and blood transfusions if needed to manage dehydration or blood loss
• Medications for clotting disorders or chemotherapy for cancers
• Close follow-up and monitoring to adjust care and enhance quality of life

Living With and Caring for a Dog With Hematuria

Depending on severity, some dogs recover under outpatient care while others require hospitalization. Responsible dog owners should strictly adhere to veterinary instructions, monitor symptoms, and ensure consistent vet rechecks. Keeping pets well-hydrated and in a calm environment supports healing. Prompt veterinary intervention greatly improves prognosis and comfort.

When to Get Emergency Veterinary Care

Any visible blood in a dog’s urine warrants veterinary evaluation quickly. If your dog shows pain, weakness, vomiting, or difficulty urinating, seek emergency veterinary care immediately. Rapid diagnosis is crucial, especially if bleeding is severe or linked to clotting disorders, toxins, or cancer. Early professional treatment is key to successful outcomes.

Summary

Hematuria in dogs is a critical warning sign suggesting urinary tract issues, infections, bleeding abnormalities, trauma, or cancer. Awareness of signs and swift veterinarian involvement is vital to secure timely treatment. By working closely with your veterinarian and providing vigilant care, you can help your loyal companion recover and maintain a high quality of life.
