Educating yourself about healthy nutrition for your dog and cat is a very good idea. One of the best ways to begin is learning how to read pet food labels. A good pet food is made from whole food ingredients, including named meats, fresh veggies and fruit, herbs and healthy oils. Most cheap commercial diets contain things your dog or cat shouldn't be eating, such as by-products, corn soy, unnamed meat or grain meals, rendered fat, and/or artificial preservatives and coloring. If you see any of these by-products and such listed cheap ingredients on your pet food bag please put the product back on the shelf. By becoming a savvy pet food label-reader and avoiding these low end ingredients, you are taking a big step towards protecting your pet's health .
