What is this beautiful appendage that deer wear atop their heads so proudly? The Master's handiwork has been created from nutrients such as calcium and minerals available in the deer's body. Annually, the velvet, protective covering dries and the deer sheds this headdress, making way for a new set to grow. Can you say "recycle"? This nutrient-packed, marrow-filled bone that has served it's 1st purpose and then been cast aside, now becomes a long lasting, natural chew that dogs love. Contains larger sections of antler.
