Abstract
A pet chew may be manufactured by co-extruding multiple compositions to form a layered construction. Separate extruders may be provided to tailor processing conditions to heat and/or shear sensitive compositions, such as nutritional additives, and additives that deter an animal from chewing, the respective extrudates may be combined such that relatively higher levels of additives may be provided as an inner or outer layer.
