So how do you identify a good, healthy food? It is exceedingly unlikely that you'll be able to find a high-quality food in a supermarket or big-box store; you will probably have to go to a specialty retailer or order online. Fortunately, even if you don't have a local pet supply store in your neighborhood, big chains like PetSmart and PetCo are rapidly expanding their stock of premium brands, and online retailers such as Amazon carry just about every good brand in the U.S. and Canada, so it's easier than it has ever been to obtain quality food.
