OVERVIEW: FEEDING TIPS FOR HEALTHIER DOGS
However, one area of research that does appear strong is that obesity increases the risk of cancer development. A 1998 study reported that female dogs with obesity by 1 year of age were more likely to develop mammary tumors than dogs who maintained a healthy weight.
Additional studies are required to help us understand the link between diet and cancer risk in dogs. Fortunately, the first long-term study for cancer risk factors in dogs is currently underway. The Golden Retriever Lifetime Study began in 2015 and continues to follow over 3000 Golden Retrievers across the US. The purpose of this study is to collect information regarding nutrition, lifestyle, behavior, and genetics to understand better how these factors contribute to cancer risk.
While more research is needed to understand the association between diet and cancer risk in dogs, prevention starts by meeting your pet’s nutritional requirements and ensuring they maintain a healthy weight. Your diligence regarding your dog’s diet and health is vital and checking your dog’s food for potentially harmful substances is key. Unfortunately, researchers have found cancer-causing chemicals (carcinogens), such as commonly used preservatives like ethoxyquin, acrylamide, and the fungus aflatoxin, in various dry and canned dog foods. To try and limit the level of carcinogens in your dog’s diet, you might consider preparing homemade dog food or feeding your dog a higher-end, organic dry food equivalent that does not have carcinogenic preservatives. Reading the labels and discussing food options with your vet will help ensure your dog gets the proper nutrients.
Providing your dog with nutrient-dense food while monitoring their weight also ensures their immune system is working in prime condition. The immune system is designed to eliminate unwanted or unexpected carcinogens in everyday life. A diet filled with cancer-fighting foods can help your dog’s immune system get rid of the carcinogens more effectively.
