Land toys don't deserve all the credit. This bone, made to float in the water, is guaranteed to resist dog damage and is perfect for that hot day in the pool or a trip to the beach. Plus, when it's time for a clean, you can pop this bad bone directly in the dishwasher to get it sparkling again.

According to the brand, this bone bounces and floats, and is great for playing tug, fetch and any other game you can think of. Plus, it's available in three bright colors and three versatile sizes.
