Understanding Dog Food Manufacturing: Ingredients, Process, and Legislation
Dog food is typically manufactured through a process that includes ingredient selection, mixing, cooking, shaping, and packaging. This article provides an in-depth look into the dog food manufacturing process, highlighting key ingredients, the production steps, and oversight regulations to ensure safety and quality.
Ingredients in Dog Food
Dog food is made from a variety of ingredients designed to provide balanced nutrition. Common components include meats such as chicken, beef, or fish, grains like rice or corn, vegetables, and added vitamins and minerals. The exact formulation varies by brand and type (wet, dry, or raw), but the goal is to meet the dietary needs of dogs.

It is important to note that the quality of ingredients can vary widely, and some companies prioritize profit over the nutritional quality of their products. Cheaper ingredients, such as grains or corn, may be used to maximize profit margins. Many dog foods are marketed with images and packaging that suggest the presence of high-quality meat, but this is often not the case. Animal fat is added in token amounts to meet AAFCO (Association of American Feed Control Officials) requirements, while cheaper protein sources, such as corn, are used as a cheaper alternative to more biologically available protein from meat. Vitamins and minerals are often added after most of the nutrient content has been destroyed during the high-temperature cooking process. This process ensures a long shelf life, but at the expense of proper nutrition for dogs.
The Manufacturing Process of Dog Food
The dry mix is combined with wet ingredients (water and steam) in a preconditioner, which hydrates the powders, creates a dough, and starts the cooking process. The dough then enters a machine known as an extruder, which cooks the dough under pressure. At the end of the extruder, the dough exits under pressure through a die plate, creating ribbons of pre-specified shape. These ribbons are then sliced while they expand into the pre-specified size using a rotary cutter. After extrusion and cutting, the kibbles are air dried in an oven to remove moisture and then cooled. Reducing the moisture content is crucial for maintaining freshness and preventing food spoilage. The dough can also be rolled out, cut into shapes, and baked in an oven similar to cookies or biscuits. After drying and cooling, kibbles often enter a revolving drum where they are evenly coated with a mix of flavors to enhance taste and preservatives to prevent spoilage throughout the food's shelf life. Flavors or other coatings may also be sprayed on baked foods as they exit the oven.
Packs are filled according to the declared weight and the packaging is appropriately sealed to prevent contamination. Packages are stored in boxes or wrapped on pallets and then stored in warehouses ready for distribution to customers.
Regulation and Legislation
Whatever the pet food format, all pet products, foods are subject to strict legislation to ensure safe quality products. In the United States, AAFCO (Association of American Feed Control Officials) plays a significant role in regulating pet food. They work to ensure that products meet nutritional adequacy claims and guidelines. Additionally, FEDIAF (Fédération Européenne des Industries des Produits Alimentaires pour Animaux de Compagnie) members follow industry Codes of Practice such as the Guide to the Manufacture of Safe Pet Food. These guidelines help ensure that pet food manufacturers adhere to best practices in manufacturing to produce safe and nutritious products.
