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