I bought this having high hopes due to all the great comments on this product. After less than one hour, my 10 month old beagle/american pointer mix, had already started ripping off chunks from the nubs. My hopes were that this toy would be able to stand his constant desire to chew. After one week the toy is still intact but all 3 nubs have been chewed down by half. I give it 3 stars but will be sending back for a replacement.
