Double-Tuff is made from the same doggie-durable, bouncy, buoyant and mint-scented Orbee-Tuff® material. Its asymmetrical “doubled” design makes for amazingly unpredictable bounces, making it a toy that can stimulate a dog mentally much more than a standard fetch toy. Double the tuff. Double the fun! It is rated at 5 out of 5 chompers on the Planet Dog Durability Scale, making it suitable for most dogs. Made in the USA.
