I second Selzer's comment about antlers. My guy broke the tips off 3 carnassial teeth on an antler. We had a visit with the vet. dentist and she remarked that antlers are responsible for a lot of her business.Be careful with toys in the crate. A bored dog will chew up toys, and some will ingest them. Surgery for blockages is not cheap. A hoof, while they can be stinky, generally will keep them busy and they are unlikely to cause problems in the intestine.
People like antlers because they last longer, but a lot of vets say the break teeth, so I avoid antlers.
