KURGO SKIPPING STONESKurgo Skipping Stones will add a new, fun twist to games of fetch with your dog at the lake. Rather than repeatedly throwing a slimy ball that slips in your hand, try these durable, non toxic floating skipping "stones". They are brightly coloured to make them easy to see and they are shaped like real stones. Now you can try to beat your record for most skips while your dog enjoys retrieving it for you.
