Bladder Cancer in Dogs: Causes, Signs, Diagnosis and Treatment

Bladder cancer in dogs, specifically referred to as transitional cell carcinoma (TCC), is a malignant tumor that originates in the lining of the bladder. This type of cancer is relatively uncommon but severe and often aggressive. Here are critical points about bladder cancer in dogs:

Causes and Risk Factors

  1. Genetics: Certain breeds, such as Scottish Terriers, West Highland White Terriers, Shetland Sheepdogs, and Beagles, are more prone to developing TCC.
  2. Environmental Factors: Exposure to certain chemicals and carcinogens, such as pesticides, herbicides, and industrial chemicals, can increase the risk.
  3. Age and Gender: Older dogs are more commonly affected, and females are at a slightly higher risk than males.

Symptoms of Bladder Cancer in Dogs

  1. Urinary Problems include frequent urination, difficulty urinating, blood in the urine (hematuria), and urinary incontinence.
  2. Pain and Discomfort: Straining to urinate and signs of pain or discomfort.
  3. Other Symptoms: Weight loss, lethargy, and sometimes swelling or pain in the abdominal area.

Diagnosis of Canine Bladder Cancer

  1. Veterinary Examination: Initial assessment based on clinical signs and physical examination.
  2. Urinalysis and Blood Tests: To detect abnormalities in urine and blood.
  3. Imaging: Ultrasound, X-rays, or CT scans to visualize the tumor.
  4. Biopsy and Cytology: Confirming the diagnosis through microscopic examination of cells or tissues.

Treatment of Bladder Cancer in Dogs

  1. Surgery: If the tumor is localized and accessible, surgical removal might be attempted.
  2. Chemotherapy: Systemic treatment to target cancer cells throughout the body.
  3. Radiation Therapy: Used in some cases to shrink tumors and alleviate symptoms.
  4. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) like piroxicam have shown efficacy in managing TCC.


The prognosis for dogs with bladder cancer varies depending on the phase and progression of the disease, the dog’s overall health, and the effectiveness of treatment. Early diagnosis and treatment can improve the quality of life and extend survival time. Still, TCC is generally considered a challenging cancer to treat successfully due to its aggressive nature and tendency to metastasize.

Management of Canine Bladder Carcinoma

  1. Regular Monitoring: Frequent veterinary check-ups and monitoring of urinary symptoms.
  2. Supportive Care: Pain management, maintaining hydration, and addressing secondary infections or complications.
  3. Diet and Lifestyle: Ensuring a balanced diet and a comfortable living environment.

Preventive Measures

  1. Avoiding Exposure to Carcinogens: Limiting exposure to harmful chemicals and ensuring a safe environment.
  2. Regular Veterinary Care: Routine check-ups can help in the early diagnosis and treatment of health issues.

Final Talk on Bladder Cancer in Dogs

Bladder cancer in dogs, primarily in the form of transitional cell carcinoma (TCC), is a significant health concern that requires vigilant attention and care. While the condition is relatively rare, it poses serious health risks due to its aggressive nature and potential for metastasis. Early detection and comprehensive veterinary care are critical in managing the disease and developing the quality of life for affected dogs. In conclusion, while bladder cancer in dogs presents significant challenges, informed and proactive veterinary care can make a substantial difference in managing the disease and enhancing the well-being of affected dogs.
