Towards the end of the 19th century, the breed had become popular in America and Canada due to their dual use as a family pet and a working dog. In the early 20th century the breeders on either side of the Atlantic had created different breed standards for the Cocker Spaniel and the breed gradually diverged from one another, with the two becoming noticeably different by the 1920s. The American Cockers by now had a smaller muzzle, their coats were softer and the dogs overall were lighter and smaller. The differences were so apparent that in 1935, breeders founded the English Cocker Spaniel Club and restricted breeding between the two types of spaniel. The two types of Cocker Spaniel in America were shown together as one breed, with the English type as a variety of the main breed, until 1946 when the American Kennel Club recognized the English Cocker Spaniel as a separate breed.
