The Ultimate Oddball has a unique shape that makes it easy for dogs to pick up, toss around and play with – great for fetch. Its soft edges won’t hurt your dog’s gums. Because of the unique shape, the Odd Ball does not have a squeaker. Ultimate Construction: Each toy is made with 4 layers. 2 layers are made of industrial grade luggage material, 1 layer of plastic coating, and the other layer is made of soft fleece on the outside. All of these layers are sewn together to make one super strong layer of material. Each toy is sewn together with 2 layers of cross stitching and then 2 layers of linear stitching. After the toy is sewn together an additional piece of black trim is added to cover the four rows of stitching. This extra piece of black trim is sewn with 3 linear stitches to give the product a total of 7 seams. These toys are machine washable (air dry) and float.
