Would cancer change your dog breed preference?
That is the question I asked myself as I read some recent data on dogs and canine cancer. The data was posted on The Institute of Canine Biology but came from a scientific veterinary review article by Jane Dobson titled “Breed-Predispositions to Cancer in Pedigree Dogs”.
The data was both interesting and sad. In breeds where the prevalence of cancer is high, the attributing factor is most likely genetics. Certain breeds of dogs are just genetically pre-disposed to get cancer more than others. Whether this is due to closed breed registries I cannot say (I’m just not knowledgable enough about dog breeding to know) but it certainly does give one pause to wonder.
As I looked at the list of dogs, I automatically found myself scrolling down the list to see where Shetland Sheepdogs and Labrador Retrievers fell. Labs were higher on the list (31%) than Shelties (22%), but certainly not as high as the irish Water Spaniel (55.8%) or the Flat-coated Retriever (50.3%).
I found myself whispering a silent “Thank God” and then wondering to myself whether a higher-risk for cancer would change how I felt about a certain breed. If Shetland Sheepdogs were higher on the list would I feel differently about getting a Sheltie again? Would the data influence my decision to stay away from certain breeds? To be honest, I don’t think so, but then again, I am not the owner of a Bernese Mountain Dog or a Vizsla or a Rottweiler or one of the other breeds topping the list. Maybe I would feel differently if my favorite breed was one of these dogs. I just don’t know.
How about you? Would you choose another breed of dog if you knew cancer was more of a possibility?
