Twisted Chews Easy Tug is a durable rope toy made from 100% premium cotton rope. With its strong TPR handle and 18" size, it's the perfect toy for large dogs that like to play tug-of-war. Rope toys help keep your dog's teeth and gums clean and healthy. Unlike humans, dogs only have two cones in their eyes, causing them to see a limited pallet of colors. Blue is the darkest color they can see and yellow is the lightest. By making our toys blue and yellow, your dog sees great contrast and can find them easier.
