If He's chewing and swallowing it.. then no. That's not very healthy. But if you KNOW he's not eating it, I wouldn't see a problem. Personally, and I'm no expert, I would air on the side of caution with the chewing.. Titan's favorite toy is a stick too, but he doesn't chew it at all, he just wants me to throw it.. if he chews it's to destroy it... lol Have you tried giving him a raw marrow bone or a knuckle bone?
