Stephen and I stopped by a puppy store during work and scoped out some toys. I have given up on Nylabones after reading a bunch of horror stories about the deaths caused by swallowing the sharp pieces of plastic. We ventured in, spoke with the owner, and was recommended ANTLERZ! Yup, deer antlers. It was an expensive $11.99 but so worth it. Sumo loves to chew and chew on it. It never breaks or splinters. I definitely recommend it!
