Tuffy Pet Toys are the most durable toys available. All the layers of this toy are bonded and sewn together to make one "Tuff" Layer. Most toys have just one seam to hold the toy together. Tuffy Pet sews webbing around the edges of the toy and then sews the edges together to make each toy Tuff. Squeakers are sewn into pouches as an added layer of safety. These toys are machine washable (air dry) and float.
