Okay so maybe I'm just being paranoid, but I heard from a few people that antler chews are a great alternative to bully sticks (no mess, no smell, etc.) so I bought one for Dax. It just came in and I guess I never really thought about the fact that it's an antler (duh), and I'm actually almost a little worried that it's going to break his teeth because it's so hard, and he's the type that likes to bite things with his back teeth to try and break it in half. He's chewing on it now and trust me, he's ecstatic about it. He loves it. But I'm paranoid. Anyone had any experiences with these?
