Antlers have no odor and when the dogs chew on them they simply grind down into a white powdery substance that disappears into our carpet (I suppose you could vacuum it up but it's invisible, at least on OUR carpets . . . < eeeek! >)
We throw them away when they get small enough that a dog could choke on them (we do the same with the nylabones).
It’s just the thought. And the boys would never let me hear the end of it ... rawhide “bones” are fascinating enough!
