I have two high-bred field Labs and one half-and-halfer who's just as wild as the others - took after her AFC/NFC grandsire.
They do go through that chewing stage, but the antlers don't smell or stain, are soft enough not to hurt their teeth, and grind down to a soft powder.
Plus if you ever want to use her for a shed-hunting dog, you have her all scent trained already.
That is a great idea. We live in the woods and there are deer running about. I will have to stop at the pet store.
