An outer layer of mesh material is used to loosely cover the exterior of an animal blanket to provide a protective buffer against damage caused by impact and abrasion experienced during use. The mesh material utilized in the manufacture of the outer protective layer is made with a high-strength polyester yarn that has been extrusion-coated with a polyvinyl chloride sheath. This fiber material has been found to have physical characteristics that are particularly advantageous for this protective application. Specifically, in addition to the light weight, strength and flexibility provided by the inner core of the fiber, the PVC coating provides temperature stability and resistance to color fade, abrasion, flame, and mildew.
