The first Rottweiler was imported into the UK in 1936 by Mrs Phil (Thelma) Gray of the Rozavel kennels. This bitch was called Rozavel Diana von der Amalienburg SchH I born in May 1934 but she was not successfully bred from. Mrs. Gray continued to import more dogs, but due to the outbreak of World War II in 1939 they were sent over to Ireland for safe-keeping. After the war, attempts were made to find them and return them to England but they had vanished without trace.
The first post-war Rottweilers were imported by Captain F. Roy Smith of the Royal Veterinary Corps in March 1953. They were Ajax von Fuhrenkamp and Berny von Weyher [right]. However, this breeding pair was unsuccessful in producing a litter.
