7. Bernese Mountain Dog

With a calm, confident nature and a long, silky coat, Bernese Mountain dogs are also among the canine breeds with higher rates of cancer. With an average lifespan of about 10 years, almost 10% of Bernese Mountain dogs get a cancer diagnosis by the time they reach six years old.

Good breeding stock, as well as diet and exercise, are very important to reduce cancer risk. That’s why, before purchasing a Bernese Mountain dog, it’s essential to ask about the pup’s bloodlines to check if cancer has been an issue.

According to veterinarians, these dogs are more prone to orthopedic diseases than other breeds. Those who deal with these health issues are two and a half times more likely to struggle with histiocytic cancer than other canine breeds. This type of cancer is an aggressive disease that produces cancerous tumors in the skin.
