Our Malamute and Husky are very aggressive chewers. I always worried how big the pieces of rawhide were that they might be swallowing. Your guarantee for splinter resistant elk antlers made me feel better, so I ordered the large ones for them. They both love them, and chew on them for hours with little being worn down! They actually get tired, and stop for a while, at times! I'm happy, and they're happy! Win, win! I'll be ordering them, again!
