Dog Cancer and Their Types
Similar to other species of animals, dogs can develop some types of cancer as humans such as lymphoma and even breast cancer. Cancer is considered one of the leading causes of death in dogs. 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.
The most common types of dog cancer include:

This type of cancer usually spreads to other parts of the body and can put your dog’s life at risk. Certain breeds like Cocker Spaniels are more prone to anal cancer.

- 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.
Besides these, veterinarians also observe some other types of dog cancer such as brain tumors, lymphoma, mouth and nose cancer, breast cancer, etc.
