Dog Cancer Risk Linked to Size | Dr. Jules Benson

Pet insurance claims through Nationwide are revealing trends about which dogs are at higher risk of developing cancer.


Nationwide Pet Insurance has released several white papers looking at trends in dog cancer diagnoses. In this episode, Dr. Jules Benson explains their paper “About the Size of It: Scaling Canine Cancer Risk.”

First they looked at the likelihood of developing cancer based on the size of the dog, and found that it appears larger dogs are at higher risk. They then looked at some of the most common cancer types in dogs, and the trend remained consistent with one exception, mammary cancer. They also looked at how size affected how old dogs were when they were diagnosed.

Dr. Benson explains that this data does not mean that large dogs will get cancer and small dogs won’t. Instead, this data helps us to know which dogs are at the most risk of different cancers, as well as when we should start being concerned about signs that appear. This work can help veterinarians and owners to catch cancer earlier, increasing the chance of successful treatment.
