Must-Have Ingredients in Dry Dog Food  犬干粮一定要有的成分

★ Superior sourcesof protein: Look for dry dog foods that contain a lot of animal proteins—either whole, fresh meats or single-source meat meal. For example, you want to see “chicken meal” or “beef meal” on the label, not “poultry meal” or “meat meal.” A dog food label listing simply “meat” is an example of a low-quality protein source of dubious origin.	★ 优质的蛋白来源：犬粮内应该有丰富的动物性蛋白 - 不管是全肉，新鲜的肉或是单一来源的肉粉。而且应该清楚列出是什么肉。例如：成分表中应该写 【鸡肉】，或是【牛肉】，而不是【家禽肉】，或是【肉粉】。 如果只是标示不【肉】，就表示这个狗粮有可能采用来源不明的劣质低廉蛋白。
★ Whole-meat source as one of the first two ingredients: Better yet: two meat sources among the top three ingredients (say, chicken and chicken meal). Meat, the most natural source of protein for dogs, contains the amino acids most important to canine health. A good mix of meat proteins helps round out a dog food’s amino acid profile.	★ 优质狗粮的前几个成分，应该是动物性蛋白。对犬类来说，肉类是最天然最好的蛋白质来源，因为里面含有维持他们健康的氨基酸。
★ Whole, unprocessed grains, vegetables, and other foods. An unprocessed food for your dog has the best chance of surviving the food-making process with its nutrients—vitamins, enzymes, and antioxidants—intact.	★ 优质的狗粮应该营养均衡，谷类和蔬果的比例很重要。若饲料的蔬果种类少，谷类副产品很多，表示那并不是一份营养均衡的狗粮。而且这些谷类和蔬果要尽量保持未加工的原型，这样其中的维他命，酵素和抗氧化物才能最大化的保存。
★ Steer toward organic ingredients and/or locally sourced ingredients.	★ 尽量选有机食材或是当地的食材
