Antlers are awesome! Our dogs love them. We actually had to stop using them for one of our dogs, our bull terrier, because he actually got too excited when we gave them to him. Instead of gnawing on them, he would immediatley try to break them with his back teeth so the vet told us to give hime something softer so he wouldnt break his teeth. We now give him root chews which are large chunks of roots that he can chew on for a long time but are much softer. They don't have the nutrients of antlers though. Our lab still gets antlers and we actually have to separate them in different rooms when they get their chews that way the the bull terrier doesn't steal the antlers. Here's a helpful guide for the roots for anyone who has a dog with the same issue as ours: http://www.smartdogguide.com/everyth...hews-for-dogs/
