I have two Chesapeake Bay Retrievers - VERY high energy dogs. One is 10 mo., another is 2 years. They love this thing to death. My 10 mo chessie loves to retrieve it in the water more than chew on it, but it is great for throwing - throws a good distance like a heavy frisbee. Cute, fun toy. Love the bounciness and bouyancy of the product.Love that its recycled. Cost effective. LOVE THIS PRODUCT!!! Will definately buy a new one for birthday presents!!
