Dog facial action coding system (DogFACS)


The Dog Facial Action Coding System (DogFACS) is a scientific observational tool for identifying and coding facial movements and dog emotion in dogs. The tool works by identifying the facial muscle movements that dogs use to produce facial expressions.

DogFACS identifies observable facial changes associated with underlying muscle movement allowing an objective, reliable and standardized measurement of facial movements.

Benefits of using our facilities

DogFACS helps scientists, vets, dog trainers and other animal behavior professionals to code and analyse dog facial expression, so they can describe and understand the communication of domestic dogs. DogFACS can, therefore, be used to assess dog behaviour and dog welfare.
