We've been through every toy on the internet and in the stores. Aside from hard as rock nylon bones, this is the only toy that has outlasted our 3 golden retriever, 1 great pyrenees toy testing team. They chew and chew, pull, carry, and play with these hurleys constantly. They love the squishiness of the material. After one year the first one is still intact. We now have one of each color and they are never ignored.
