Your pal will be catching Tuffy's Gray Mouse Mo Dog Toy by his toes all day long. It's made with three layers of safe, non-toxic fibers: soft fleece, industrial grade luggage material, and plastic coating. All three are fused and sewn together to make one ultra "tuff" layer, ensuring this toy is just as durable as it is fun. For interactive play with one or multiple dogs. Mo does not squeak! This toy is great for indoor use because of its soft exterior, perfect for outdoor use because it floats in water, and easy to clean because it’s machine washable.
