1. A method for forming chew toys of selected shape from edible compositions by extrusion, comprising the steps of: providing an extruder including a barrel and a die; providing an extrudable composition comprising an edible composition and water, the extrudable composition having a water content of between 10% to 40% by weight; introducing said composition to said barrel and subjecting said composition to shear and heat to form a melt; conveying said melt through said die to form an extrudate; passing said extrudate between cooperating surfaces, one of said surfaces having mold cavities, which mold cavities form the shape of said chew toy while said extrudate is at a temperature and moisture level that allow said extrudate to form within said mold cavities, wherein said mold cavities reside on a rotating surface and said other of said surfaces is a stationary surface; and forming said extrudate into the shape of a chew toy comprising a central shaft and a bone condyle at each end of said shaft, wherein a cross section of said central shaft varies over its length and said chew toy after forming has a water content of 10% by weight to 15% by weight.
