Shaped just like real stones, you can skip them over the water as far as you can, wait for your dog to bring them back, and then repeat until you beat your personal best or one of you passes out from exhaustion. Fun is just a stone’s throw away! * Non-toxic * Dishwasher safe * Super durable * Easy to spot colors * Never gets waterlogged * Floats well even after a good chewing   Toys are not covered by our Lifetime Warranty or Repair & Replace Service, because toys, after all, are mostly about chewing. We believe our toys are very durable but some dogs are tougher chewers than others.
