狗粮是人类用来喂养狗的食物，因人类生活型态改变，饲养狗转趋为家中宠物，人类进而发明能长期保存、方便喂食饲料产品，发明至今已有约六十年历史。和所有食肉动物一样，狗也拥有锋利的尖牙和较短的胃肠道，从而更适合肉类的消化。尽管有这种自然界的食肉优势，狗也仍设法适应了数万年仅仅利用肉类、非肉类和剩菜，并热衷于各种各样的食物。仅在美国，2007年狗的饲养者就一年花费于购买商业化制造的狗粮总共达85亿美元。 一些人自己制作狗粮，或从杂货店或健康食品商店购买狗粮，或给生食。

Dog food refers to food specifically intended for consumption by dogs. Like all carnivores, dogs have sharp, pointed teeth, and have short gastrointestinal tracts better suited for the consumption of meat. In spite of this natural carnivorous design, dogs have still managed to adapt over thousands of years to survive on the meat and non-meat scraps and leftovers of human existence and thrive on a variety of foods.
