Antlerz is made from a natural material that is rich in minerals, does not splinter and comes from a completely renewable source: Deer Antlers!  Naturally shedding yearly, the deer will re-grow another set.  Shed antlers are cleaned, cut to an appropriate size for your dog, and packaged.  These natural chews will hold up and last far longer than chews made from plastic, compacted starch, or rawhide.  Your dog’s chewing action will grind the antlers slowly – even in the most aggressive chewers!  Your dog won’t be able to get enough of these.  Available in multiple sizes and in sets at Amazon
