Older dogs are susceptible to developing cancer in their body. Research shows that almost 50% of dogs over 10 years develop cancer at some point. Cancer itself refers to the uncontrolled growth of cells in the body. If left untreated, cancer can spread all over the body of your dog via circulatory or lymph systems. However, maximum cancer cases in dogs are curable if it is recognized in its early stages.

  1. Urinary Bladder Cancer

Only a few types of tumors can cause bladder cancer in dogs. Transitional cell carcinoma is the most common tumor that develops in the deep layer of the urinary bladder of older dogs. As the tumor grows, it blocks the urethra and obstructs the normal urine flow. This requires a surgical operation to resolve. Most of this case is found in males rather than females. Certain breeds like Shetland sheepdog, Scottish terrier, and Beagles are most prone to develop bladder cancer.
