Old Dog/New Trick

In an effort to keep 16yr old Riley young, we gave her this puzzle. Under each white bone is a kibble and Riley quickly smells the treat. She wastes no time getting to the reward and even mixes it up sometimes using her nose to push the bone away other times trying her paw. Engaging her drive to hunt and seek, stimulating her olfactory, providing opportunity to puzzle it out, Riley seems to like this game.
