For example, bone cancer, or osteosarcoma, is considerably more frequent
among large and giant breeds of dogs, such as the Irish Wolfhound, Great Dane, Rottweiler, Labrador and Golden Retriever, Greyhound, and Saint Bernard, because their bones are stressed by carrying so much weight.
In this study, researchers found that in 20 % of cases
among large breed dogs
and in 52 % of cases
among giant breed dogs, bloat was actually directly related to having a raised food bowl.
