Dogs of similar dimensions exist in modern Scandinavia, called the Swedish Vallhund, and it is claimed by some historians that these two breeds share a common ancestor. In the late 19th century, farmers began to switch from cattle to sheep, but the Corgi is not suited for working sheep. Similarities between the Welsh Corgis have been attributed to crossbreeding between the two, or simply selected breeding from those who wished to have the Cardigan variety appear closer in nature to the Pembroke. The first recorded date for Corgis appearing in the show ring in Wales is 1925. Captain J. P. Howell called together a meeting of breeders of both the Pembroke and the Cardigan varieties and formed the Welsh Corgi Club, with an initial membership of 59 members. A general breed standard was drawn up, and Corgis began to appear in conformation shows. Until this point, neither breed had been specifically bred for looks. Members of this club were primarily interested in the Pembroke variety, although the Cardigan variety also appeared. At that point, the breeds were referred to as the Pembrokeshire and Cardiganshire varieties; the names were later shortened. There were a number of disputes between breeders of the two types in early shows, as judges who were breeders of one type would often favour them. The Welsh Corgi appeared at Crufts—a dog show held annually in the United Kingdom—for the first time in 1927. The first championship was awarded at a Cardiff show in 1928, to a red and white Pembroke bitch named Shan Fach. The breeds continued to be judged together until 1934, when the Kennel Club recognized each breed separately. In that initial registration, some 59 Cardigans and 240 Pembrokes were listed in the pedigree books. The decisions about the breed to which each dog belonged were sometimes left to the owners, who were free to choose whichever they felt was the most appropriate. The first dog to be named best-in-show at an open conformation show was Ch. Bowhit Pivot. Cardigan Welsh Corgis continued to be rarer than Pembrokes, with only 11 registrations made in 1940. Both breeds survived the Second World War, although the Cardigans registered with the Kennel Club numbered only 61 by the end of the war. Pembrokes became very popular during the postwar years in the United Kingdom; in 1953, it was ranked as the fourth-most popular breed by the Kennel Club,
