Is made from a propriety Bionic Rubber material which is 100% recyclable, FDA approved and dishwasher safe. The Bionic Urban Stick has been designed and manufactured to fit the natural curvature of a dog's mouth and has ridges along the top of the stick to make it feel as though the toy is being chewed through. The Urban Stick is also perfect for a game of throw and fetch and has weights at both ends to create a spiralling effect when moving through the air. You can also fill it at each end with your dogs favourite treats or food to make play time even more exciting. It also floats in water! So along with all these great benefits it is also as 'tough as old boots' and makes a fantastic chew toy. The Bionic Urban Stick gives hours of super fun!
