A pet chew product (10) includes an edible casing (12) having a hollow cavity (14) with an edible treat (16) disposed therein. The casing (12) has an opening (18) that militates against a removal of the edible treat (16) from the cavity (14) until the opening (18) or the casing (12) is opened further by a pet. The opening (18) permits an olfactory detection and visual detection of the edible treat (16) by the pet. An open volume of the cavity (14) is greater than a size of the edible treat (16), and allows the edible treat (16) to strike an inner surface (23,33) of the cavity (14) when the casing (12) is manipulated by the pet. The striking of the edible treat (16) with the inner surface (23,33) of the cavity (14) permits an audible detection of the edible treat (16) by the pet.
