Edible pet chews are made of one or two layers, each layer comprising a thin slice of sweet potato, and one of the layers being processed to form irregularities, the layers being rolled into a tubular body and treated with heat to form a single- or dual-layered dehydrated tube having the irregularities oriented toward the interior cavity of the tubular body, the interior cavity being fillable with a beneficial material of suitable viscosity to provide a beneficial or therapeutic effect to the animal as the animal chews on the edible pet chew.
