TUFFY toys are the most durable dog toys on the market! With up to 4 layers of material, our toys are bonded and sewn together with up to 7 rows of stitching for added durability. A protective webbing is added to the outside edge to cover the seams and strengthen the toy. Squeakers are sewn inside protective pouches for your dogs safety. This extra safety measure can give you the time to remove the toy if your dog reaches the core. TUFFY toys float in water and are machine washable (air dry).
