My English Bulldog is a heavy chewer.  I love Nylabone products because she can either: a) chew on them forever without destroying or b) if she does destroy it, it takes a long time!  This toy has not disappointed.  We've had it about 3 months now and she hasn't gotten any big pieces off yet. The reason I dropped it a star is because she just doesn't pull it out of the toy box everyday like most of her other Nylabone toys.  I'm not sure if she doesn't like the flavor, the texture, or shape but she only chews on it about twice a week vs. everyday.
