Right now, in your local pet food and supply store they are selling so called "indestructible" elk antler dog chews that will run you anywhere from $20-75. We have one, currently #underthecouch, and it's quite a lot smaller than it was when it was purchased.
This is Snowman. Lenox carries him around like a safety blanket. He's lost a little paint here and there and his squeaker never worked ( #bonus) but he's certainly not destructed. He also cost $1.
