I gave this to my Great Dane Puppy a while back and now even at 152 lbs this is still her favorite toy.  She LOVES this thing and can chew on it for hours.  Have been meaning to get another for her brother to have since he's annoyed he never gets to play with it.  I would recommend this highly.  Dogs can destroy almost anything it's in their nature.  Mine hasn't killed this yet that's a good investment.
