An improved pet toy is generally ring-like and is rollable along a surface, such as the ground. The pet toy includes a resilient foam core that is surrounded by an elastomeric outboard portion and a fabric inboard portion that are affixed to one another and to the core. The outboard portion has a roughened surface that provides traction with the ground and enables the pet toy to roll in various fashions. The fabric inboard portion includes a stiffening structure in the form of a rib that resists deformation of the pet toy in a radial direction toward and away from a center of the toy.
