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. Our toys are built to last, but keep in mind that no toy is indestructible. Tuffy toys are designed to be used for interactive play and are not chew toys. Please be a responsible dog owner and only allow your dog to play with the toy under supervision. Do not allow your pet to ingest any portion of the toy. We strive to make our toys the strongest and safest on the market. As loving dog owners, we only want the best toys for our dogs and yours!
