The Cauchois, commonly referred to as the "Norman bidet", is not listed in the
Domestic Animal Diversity Information System (DAD-IS). The nineteenth-century zoologist proposed a British origin for the breed, while
Achille de Montendre suggested it derived from the
Flemish Horse. In the seventeenth and eighteenth centuries, the Cauchois was highly sought after by country gentlemen for its robustness and elegance. A report by M. Le Prévost, written at the time of the reorganization of the stud farms, details the breed's significance in the Pays de Caux under the
Ancien Régime: "Before the Revolution, the Pays de Caux possessed a species of horse that was particularly advantageous to it, known as Cauchois horses. They were the result of native mares combined with stallions of the Norman or Danish breed, widespread in large numbers in our various cantons". In 1820, Cauchois stallions were noted in various stud farms, including those in
Amécourt, created in 1815; and in
Maintenon, in the
Eure-et-Loir region. In 1846, an article in the weekly ''L'Illustration'' described the breed as "the type of draft horse", noting that it was "improperly called Boulonnais". Horses bred in the Pays de Caux were nicknamed "chevaux du bon pays (horses from the good country)" in the trade, to emphasize their qualities and to differentiate them from the heavier Picardy drafts, nicknamed "chevaux du mauvais pays (horses from the bad country)". He also notes that the Boulonnais and Cauchois breeds are tending to merge. In 1877, the Société centrale d'agriculture du département de la Seine-Inférieure in Rouen proposed various measures to "improve Cauchois horses", including crossbreeding with
Thoroughbred or
half-blood stallions, and a
Percheron stallion. The decline of the Cauchois breed began with the advent of railroads, which provided competition as a draft horse, as well as the tilbury, which favored mixed-breed horses. André Sanson noted this decline as early as 1867, In 1923, Paul Diffloth explained that the Cauchois had been suppressed by competition from other breeds, and modified by cross-breeding. == Description ==
