Goughnuts Red Ball - Made from the same materials that other Goughnuts toys are made, this interactive toy is safe and durable as the others. The Red Ball does not have the same red core safety indicator as the rest. Instead, it IS made from the safety indicator material. Since the toy is interactive, check the toy after play for any signs of wear. If your dog does compromise the toy, it is still backed by the same Lifetime Guarantee that protects your purchase.
