Dog food is a high-end animal food positioned between human food and traditional livestock feed. It's a specialized food designed to provide dogs with basic nutrition. Its main ingredients include corn, dehydrated poultry meat, animal fat, and minerals, containing essential nutrients such as protein, fat, and carbohydrates. It also has health benefits, including preventing certain diseases. Dog food can be categorized by form (dry, extruded, semi-dry, soft/wet, wet, etc.), by processing method (extruded, steamed, etc.), and by function (puppy food, adult dog food, etc.).
