I have ordered the extra-large whole antler chews several times and I will continue ordering from Yellowstone Antlers. These chews keep my dogs busy for hours. They are softer than beef bones or knuckle chews, which prevents them from wearing down my dogs teeth. But, they are hard enough that my "enthusiastic" chewers don't destroy them in ten minutes (which they do with the black extreme chewer kongs). I highly recommend these antlers and this company!
