The bearded collie history is a combination of fact and legend. Kazimierz Grabski, a Polish merchant, reportedly traded a shipment of grain for sheep in Scotland in 1514 and brought six Polish Lowland Sheepdogs to move them. A Scottish shepherd was so impressed with the herding ability of the dogs that he traded several sheep for several dogs. The Polish sheepdogs were bred with local Scottish dogs to produce the Bearded Collie.
It is generally agreed that Mrs. G. Olive Willison founded the modern bearded collie puppies in 1944 with her brown bitch, Jeannie of Bothkennar. Jeannie was supposedly a Shetland Sheepdog, but Mrs. Willison received a Bearded Collie by accident. She was so fascinated by the dog that she wanted to begin breeding bearded collie puppies, so she began searching for a dog for Jeannie. While walking along the beach, Mrs. Willison met a man who was emigrating from Scotland; she became the owner of his grey dog, David, who became Bailie of Bothkennar
