With a little help from Jean, John completed a beautiful puzzle of a sheepdog. Did you know that Australian shepherd dogs are happiest when working, herding sheep or providing search and rescue services? It is believed that a Scottish Border collie was sent to Australia to help ranchers herd their sheep. There, it was crossed with a merle collie and later litters crossed with a native dog called a dingo, which gives the breed its stamina. These wonderful puzzles are from Active Minds.
