Wow! This antler (whole-large) is the ONLY chew that my dog has not splintered or destroyed within 2 hours. I’ve had the bone a full week and she chews on it HOURS a day. No splintering. It is a little bit stinky, and that tells you how fresh the bone is, and that helps create allure. A friend told me that his heavy chewers worked on a Yellowstone Elk Antler for over a YEAR. I can believe it. Wow and thank you! I’m a fan!!!
