New research shows that certain cancer in dogs may be preventable with diet changes, according to an article on naturalnews.com.

The research was presented by Demian Dressler, DVM, at the 2010 Institute of Food Technologists Annual Meeting & Food Expo in Chicago. Dr. Dressler said the key to preventing cancer is to limit the amount of omega-6 fatty acids, which can cause blood clotting and cell proliferation, in a dog's diet. These omega-6 fatty acids are often found in dog treats and many commercial dog foods, according to the naturalnews.com article. It is important to monitor a dog's weight too, as Dr. Dressler cited studies showing obesity limits the production of the adiponectin hormone that inhibits the growth of cancer cells.
