I received this through the mail yesterday and well my 9 month old Pitbull is tearing it apart as I type this review out.The tire tread is the first thing that he chewed off now he is ripping the side walls right out of it. The Kong brand makes a tough dog toy and i'd recommend that over this every day of the week, over the two months my Pitbull chewed on the kong it barely has a dent on it this toy however is not a Kong or as tough as one.
