Symptoms of Bladder Cancer in Dogs

The most common type of bladder cancer found in dogs is Transitional Cell Carcinoma (TCC).
TCC is an aggressive malignant cancer that invades the bladder walls causing obstruction to the urinary tract which in turn affects the natural flow of the urine. The cancer will normally spread to the lymph nodes and to other organs such as the lungs and liver.

Intravenous chemotherapy with a drug called Mitoxantrone is usually the most effective treatment for dogs with bladder cancer. Non-steroidal, anti-inflammatory drugs such as Piroxicam are taken orally along with the chemotherapy to try to stabilize and shrink the tumours. Piroxicam alone has is capable improving and extending the lifetime of the affected dog and also provides relief of bladder pain.
Radiation Therapy:
Radiation therapy can be quite effective over a long period of time. Small amounts of radiation are induced each day over a 3 – 4 week period.  It is often used after other therapies as a method to destroy the last remaining cancerous cells.
