During dog domestication, humans bred different breeds for specific traits. The gene pool for each specific breed narrowed, and this resulted in different health issues in different breeds. It has also increased the risk of cancer in dogs.
Cancers can occur due to many reasons, including genetics and environmental factors like diet and exposure to carcinogenic substances. While there is no guarantee that any dog will be free from cancer for their entire life, some breeds are less prone to cancer than others.
Do you know? Both in humans and dogs, the increased size correlates with increased cancer risk. In dogs, it’s the breed size while in humans, it’s height.
The most common types of canine cancers include mast cell tumors, osteosarcoma, lymphoma, hemangiosarcoma, and melanoma.
Here are the top dog breeds least prone to cancer.
