We bought one of these from a local store for our 4-year-old 70lb black lab. We're not buying the hard plastic nylabone chews anymore; we should have stopped after we had problems with the first, but we figured it could have just been that particular product. He chewed chunks off these toys and choked on them. He didn't get hurt, but we did have to throw out a toy that lasted 20 minutes. What a bummer.
