Watch: Why Golden Retrievers have a higher risk of cancer

A Colorado-based animal foundation is examining the high rates of cancer in golden retrievers in a study to determine what genetic and environmental factors may play a role in the disease. The Colorado-based Morris Animal Foundation recently got the first lifetime study of 3,000 purebred golden retrievers up and running after signing up the first dogs in 2012. Golden retrievers die of bone cancer, lymphoma and a cancer of the blood vessels more than any other breeds.
