Pellets of dry dog food, called kibble, are produced by extruder. The variety of tastes are avaliable by coating drum.

Dog food is plant or animal material intended for consumption by dogs or other canines. Special types of dog food, given as a reward, and not as a staple, are known as dog treats.

Pellets of dry dog food, called kibble, are produced by one of two methods, extrusion and baking.

During the extrusion process, cut dough or a mixture of raw materials is fed into an expander, while pressurized steam or hot water is added. When removed from the high pressure that results, the pellets puff up like popcorn. The resultant kibble is allowed to dry, then sprayed with vitamins, fats and oils, or any other ingredients that are not heat-tolerant.

If extruded kibble is exposed to air for too long or not properly stored, the fats and oils added after cooking can become rancid, and vitamins and minerals in the food may be destroyed by heat during storage or shipping.
