'Cynology' (from Greek: κύων (gen. κύνος) , ''kyn'', "dog"; and λόγος, ''logos'', "knowledge") is the study of
dogs. The word appears to have been taken into specialized
English language usage (i.e., within the community of the canine fancy) from the French (''cynophilie'', dog amateurism; ''cynologique'', of dog studies, probably popularized by the title of the
Fédération ''Cynologique'' Internationale). The word is not yet found in major English dictionaries. κυν is also the source of the English word ''cynic'', and is indirectly related to ''canine'' and ''hound''.
Cynologists (scientists who study cynology) concern themselves with
canine evolution,
breed development and differentiation, canine
behavior and training, and canine history. The discipline was virtually non-existent prior to the last quarter of the nineteenth century, when
purebred canine registries began to be organized, starting in 1873 with the founding of
The Kennel Club in the
United Kingdom.
