"my son has a 50 lb puppy who likes to chew and destroy all his toys. this is our 3rd bone since he has eaten 2 of them already. best bone available. our dog carries this heavy big bone all over the house, up and down the stairs, and even tries to sleep with it. keeps him busy for hours at a time. i use to save this bone for only when we left him in the house alone, but lately he has been enjoying the bone every time he visits-and the last time he was over he even took the bone home. he would not put it down when it was time to leave. hence i am now buying 2 more."
