I have never written a review before, and I shop 4-5 days a week on Amazon. My 5 month old puppy LOVES these chew toys. When I first opened the box I was worried because they were so hard, but Poppy went crazy. He chews on them, tosses them and retrieves them, runs in circles around them and barks, and when he finally settles down will chew them and make these pig snort sounds of contentment. I have bought a lot of toys for my new puppy… But these are the best by far!
