Bladder masses in dogs are rare. They make up around 1-2% of all tumours identified in dogs. Most bladder masses in dogs are cancerous and life-limiting. Middle-aged, female dogs and certain breeds are most at risk of bladder mass tumours.

Bladder masses in dogs cause problems passing urine. Bladder stones may feel like masses, but they’re not made of tissue. Bladder stones can be removed or dissolved. Bladder tumours are attached to the bladder wall. The first signs are likely to be difficulty peeing or blood in the urine. Bladder tumours are aggressive. With cancer treatment, survival time is up to a year. Prompt identification and treatment offer a better outlook. Always seek help from a vet if you notice anything abnormal when your dog pees.
