Cynanthropy, sometimes spelled kynanthropy, is applied to shapeshifters who alternate between dog form and human form, or to beings that do not shapeshift but possess combined dog and human anatomical features (Hamel, 76).
It is also used for real persons suffering from the delusion that they are dogs (Ashley, 37).
The term existed by at least 1901, when it was applied to myths from China about humans turning into dogs, dogs becoming people, and sexual relations between humans and canines (De Groot, 184). After lycanthropy, cynanthropy is the best known term for a specific variety of therianthropy.
