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 for added durability. Most dog toys have just one seam to hold the toy together. Tuffy toys can have up to 7 rows of stitching. Most Tuffy toys include an additional piece of black trim which protects the outside seam and makes the toy even stronger. Tuffy Toys are durable, soft dog toys made with multiple layers of durable materials on the inside. The toy seams are closed using multiple rows of stitching for added durability. Machine washable, and it floats!
