The first Volume of the French Studbook “Livre des origines français” was published in 1885 – in 1926 the system of starting a dog’s name with the same letter in a year was installed. In 1973 the Société centrale canine decided to switch to a new system, starting with the Letter I and omitting the following letters: K, Q, W, X, Y and Z.
