JW Megalast Rubber Chew Ball
This ball is absolutely indestructible. My Golden lost his first one and it took two months to find a replacement from Pet Mountain. He destroyed at least six other balls during that time. Recommend the 3" size for a 65# dog, any dog bigger than that go with the 4". Awesome product, plus it's hilarious when he barks with it between his teeth.
