The popularity of the breed during the early 20th century was such that dogs were being exchanged for hundreds of guineas. As of 2010, the Westie is the third-most popular breed of terrier in the UK, with 5,361 puppies registered with the Kennel Club. However, this is a decrease in numbers since 2001, when it was the most popular terrier breed, with 11,019 new dogs registered. The breed's position in the United States is more stable with it remaining in the top third of all breeds since around 1960. It was ranked 30th-most popular in 2001, based on registrations with the American Kennel Club, which has varied around the 30s in the decade since, with it ranked 34th in 2010.
