How to grade your dog's food:
Start with a grade of 100:
1) For every listing of "by-product", subtract 10 points
2) For every non-specific animal source ("meat" or "poultry", meat, meal or fat) reference, subtract 10 points
3) If the food contains BHA, BHT, or ethoxyquin, subtract 10 points
4) For every grain "mill run" or non-specific grain source,subtract 5 points
5) If the same grain ingredient is used 2 or more times in the first five ingredients (i.e. "ground brown rice", "brewerâ?Ts rice", "rice flour" are all the same grain), subtract 5 points
6) If the protein sources are not meat meal and there are less than 2 meats in the top 3 ingredients, subtract 3 points
7) If it contains any artificial colorants, subtract 3 points
8 ) If it contains ground corn or whole grain corn, subtract 3points
9) If corn is listed in the top 5 ingredients, subtract 2 morepoints
10) If the food contains any animal fat other than fish oil,subtract 2 points
11) If lamb is the only animal protein source (unless your dog is allergic to other protein sources), subtract 2 points
12) If it contains soy or soybeans, subtract 2 points
13) If it contains wheat (unless you know that your dog isnâ?Tt allergic to wheat), subtract 2 points
14) If it contains beef (unless you know that your dog isnâ?Tt allergic to beef), subtract 1 point
15) If it contains salt, subtract 1 point
Extra Credit:
1) If any of the meat sources are organic, add 5 points
2) If the food is endorsed by any major breed group or
nutritionist, add 5 points
3) If the food is baked not extruded, add 5 points
4) If the food contains probiotics, add 3 points
5) If the food contains fruit, add 3 points

大家可以在犬粮背面自己算算自己的犬粮合不合格,如果是F的话我直接建议你可以丢掉了,以免伤害狗狗的性命。Pedigree他家劝你们不要吃,长期是危害狗狗的,还所谓宠物食品4D的概念和肉类副产品的解释 :
1997 年,Ann N. Martin 写的一本书 - "Food Pets Die For: Shocking Facts About Pet Food" 出 版了,内容讲及由兽医诊所及动物收容所收集的4D动物,原来就是猫/狗等宠物食物中蛋白质的来源。各种 各样的动物,如被车撞死在马路上的,在动物园死亡的,加上兽医诊所及动物收容所收集的由于疾病而死的 (包括被施以安乐死的)或残缺的动物,都会有专门收集这些已死动物尸体(DEAD STOCK) 的收集商,再送到处理场处理。
越来越多的兽医都相信,很多造成猫/狗死亡的疾病原因都来自加工过的宠物食品﹐1995年12月﹐英国的British Journal of Small Animal Practice 出版了一份文章﹐来容指加工的宠物食品压抑免疫系统,导致肝,膀胱,心脏及其他疾病。而在Stockholm的Karolinska Hospital 的Dr. Kollath 医生,他带领着一个动物的研究,发现当年幼的动物被喂饲以煮过的及加工的食物,初期的健康状况良好,但是,当牠们到达成 年事,动物们会加速衰老,及发展慢性的疾病(例如关节炎) ;而另一组的动物喂饲以天然食物(RAW FOOD),则衰老的过程比较被喂饲以煮过的及加工的食物的动物慢﹐而且亦没有其他退化的疾病。
肉类副产品:(By-product)是去除肉类优良肉品的部分,剩下一大堆的内脏,头,脚,甚至管理不好的还会有粪便,杂渣,羽毛全部混在一堆经过乾燥油炸制成饲料。By-product meal责是级数更低一级的材料。
由1986年开始世界各地的宠物研究中心,都做著同一样的研究,分开喂饲不同的犬种,(一组)喂饲纯天然制造的狗粮、(一组)喂饲4D及副产品制造的狗粮,经过多年後集合回来的数据得到以下的结果:
喂饲4D及副产品制造狗粮的犬只,初期的健康状况良好,发育非常之正常,但到了後期发现与喂饲纯天然制造狗粮的犬只相比较下,它们的衰老速度快出20%以上寿命短27%。到中、晚期研究中更发现犬只出现多种疾病,大部份毛病集中於:免疫系统失调、心脏病、肝病、肾病、糖尿病、膀胱癌及多种退化性疾病等。。。!在某些报告中,有个别犬种例如:金毛寻回犬、拉布拉多寻回犬、北京犬、西施犬、吉娃娃、松鼠、腊肠犬等,这些存在著遗传性疾病的犬种,有大部份犬只都有出现它们的遗传性疾病,部份还会提早出现,有些报告例明如金毛寻回犬、拉布拉多寻回犬与及一些中大型犬种,它们出现的遗传性关节疾病特别多!有些甚至在发育时期巳出现! 很多兽医都相信,4D及副产品制造的狗粮中的肉娄来源,最危险的是因疾病至死的动物尸体,它们有 (癌症、细菌感染至死的原因),这些不良肉类存在有不良的基因,使犬只身体基因发生特变,改变犬只身体机能及免疫系统功能!这些不良的基因不可能在三、五年间 影响到犬只的健康,当犬只长期食用这些副产品制造的狗粮时,它的基因也就会慢慢地改变!
