Are mixed-breed dogs less prone to cancer than purebreds? Are some breeds of purebred dogs more—or less—likely to have cancer than the average across all breeds and mixes? Do some kinds of cancer hit some breeds worse than others? Every practicing veterinarian has an opinion based on many difficult diagnoses, but what does a biostatistical analysis of millions of pet-health insurance claims show? Nationwide’s veterinary analytics team looked at the cancer claims of 1.61 million dogs from 2015 to 2021 and found the following:
Purebred dogs as a group have a higher risk for cancer claims than do crossbred and mixed-breed dogs, at 1.9 times the relative risk.
The relative risk for cancer claims in purebred dogs varies significantly:
By breed and size. While some breeds show up as very high risk, other breeds are below the relative risk for all dogs.
By breed and affected body system. The literature has long-established that some purebreds are over-represented in specific cancer types. Nationwide’s data allow us to not just quantify those values, but also identify which other breeds and body systems may be at greatest risk.
Risk by breed
Boxers, Beagles and Golden Retrievers have the highest relative risk for a cancer claim in the Top 25 breeds by popularity, while Pomeranians, Chihuahuas and French Bulldogs have the lowest. Toy and small dogs of all kinds consistently had lower relative risk for a cancer claim, a finding that will be explored in greater detail in the next paper of this series.

Risk by body system
While not surprising to see Boxers over-represented in skin cancers, Goldens in splenic tumors and Beagles in bladder neoplasms, data from more than 1.6 million Nationwide policies allowed us to quantify those relative risks as well as uncover novel insights into other breed and body system data. To see how high the relative risk for bone cancer is in Rottweilers, or in which other cancer body systems Golden Retrievers are overrepresented, see the link to the full white paper above.
