Uncovering the 7 Dog Breeds Most Prone to Cancer

Dogs, our loyal friends and cherished family members, unfortunately share with humans the susceptibility to various health issues, including cancer. Recognizing the breeds most at risk and understanding how to identify early signs of cancer can be life-saving.

This article draws its insights from the expertise of Dr. Jennifer Coates, a veterinary consultant for petMD.com, and Dr. Denise Petryk, the director of veterinary services at Trupanion Pet Insurance.

The Boxer breed is notably at a higher risk for cancer, typically living between 8 to 10 years. Common health issues in Boxers include hip dysplasia, Boxer cardiomyopathy, and occasionally brain tumors. It’s crucial for owners to watch for signs like new skin lumps, changes in coat, appetite and water consumption, weight loss, and behavioral shifts such as isolation or reduced activity. Early detection is key, and any subtle changes should prompt an immediate veterinary visit.

Rottweilers, distinguished for their remarkable strength, are also prone to cancer. Common types in this breed include lymphoma, mast cell tumors, soft tissue sarcomas, osteosarcoma (bone cancer), transitional cell carcinomas (bladder cancer), and hemangiosarcomas (blood vessel cancer). Regular veterinary check-ups are vital for early detection and management of health issues in these dogs.

Bernese Mountain Dogs have a relatively high incidence of cancer, with an average lifespan of 6 to 9 years. Serious health concerns for this breed include hip and elbow dysplasia, gastric torsion, and mast cell tumors. While the exact reasons for cancer prevalence in certain breeds are not fully clear, environmental factors may play a significant role.

According to Dr. Denise Petryk, German Shepherds have a high cancer incidence. These dogs, living on average between 10 to 12 years, need regular training sessions for mental and physical stimulation. Common health issues include megaesophagus, Von Willebrand’s disease, and hip dysplasia. Cancer in German Shepherds can arise from various factors, including genetic predisposition.

The Bichon Frise, a playful small breed with a lifespan of 12 to 15 years, is prone to health issues like allergies, patellar luxation, and liver disease. Early spaying or neutering might play a significant role in cancer prevention for these dogs.


In conclusion, being aware of the breeds most vulnerable to cancer and knowing how to spot the early signs are crucial steps in ensuring the health and longevity of our canine companions. Regular veterinary check-ups and a keen observation of any changes in behavior or physical health are essential for early cancer detection and effective treatment.

While some breeds may have a higher predisposition to cancer, preventive care and a healthy lifestyle can significantly impact their overall well-being. As responsible pet owners, it’s our duty to stay informed and prepared to provide our dogs with the best possible quality of life.
