My dog Wylie LOVES these bones -- they are the equivalent of a child's teddy bear to him. We give him one at a time until it is so worn out I can't stitch it up anymore, but I always keep a supply on hand because he can't do without! He loves to chase it when thrown, puts it under his head when he sleeps, never goes to bed without it! They hold up quite well despite chewing, throwing, etc. Do have to sew up the holes, but then it lasts longer.
