This is by far the best dog toy I have ever had. It is basically indestructible. i use it in the ocean. it rides high so the dogs can see it when it is wavy out. the rope eventually either gets chewed off or wears out and is broken in a tog of war, but it is easily replaced. My Flat coats and my aussie love it.  I have recently bought a small one iwth a rope for my maltese,
