The Bearded Collie's history is mostly fact and false. Kazimierz Grabski, a Polish merchant, traded some grain for sheep in Scotland in 1514 and brought six Polish Lowland Sheepdogs to move the sheep. 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 in 1944 with her brown bitch, Jeannie of Bothkennar. Jeannie was meant to be a Shetland Sheepdog, but Mrs. Willison was given a Bearded Collie by accident. She was so interested by the dog that she wanted to begin breeding, so she began looking for a male 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. Bailie and Jeannie of Bothkennar are the makers of the modern breed; there are only a few other blood lines, preserved in large part by the perseverance of Mr. Nicolas Broadbridge (Sallen) and Mrs. Betty Foster (Bredon). These are based on Turnbull's Blue—a Bearded Collie from working stock, registered in ISDS when ISDS still registered non-Border Collies. He breeded three litters of Bearded Collies. The breed became popular during the last half of the 20th century—helped, in part, by Potterdale Classic at Moonhill, a Bearded Collie who won Best in Show at Crufts in 1989. The Bearded Collie Club celebrated its Golden Jubilee in 2005. The bearded collie is also good natured and is good as a family pet and a working dog and a show dog.
