 In major conformation shows , the breed has been equally successful on both sides of the Atlantic . The first member of the breed to win a show championship was Ch . Morvan in 1905 , owned by Colin Young . The dog was registered at the time as a Scottish Terrier , and won the title at the Scottish Kennel Club show at the age of seven months . Because the breed was not yet recognised independently , the championship title was not retained when the dog was reregistered as a West Highland White Terrier . The first win at a major show came at the Westminster Kennel Club Dog Show in 1942 when Constance Winant 's Ch . Wolvey Pattern of Edgerstoune won the title of Best in Show . The same title was taken by Barbara Worcester 's Ch . Elfinbrook Simon in 1962 . It took a further 14 years before the breed took its first Best in Show title at Crufts , the UK 's major dog show . Ch . Dianthus Buttons , owned by Kath Newstead and Dorothy Taylor , took the title for the breed in 1976 . The most recent win for the breed at a major show was again at Crufts , this time in 1990 with the Best in Show title going to Derek Tattersall 's Ch . Olac Moon Pilot .
