My dog is a super aggressive chewer

My dog is a super aggressive chewer, so he gets fixated on shredding and destroying anything. I purchased from these guys twice, and the first antler I got was months ago, and it's still going strong. Some antlers chip and shave off right away, and this one has been taking a long time to get to half the size of its original size. 2nd purchase though, however, was a lot skinnier and "softer" antler than the first one, and it was gone within a couple weeks. I wish I could get something similar to my first purchase every time.
