Physical properties

Formation & geological history

Formed via selective breeding of English Bulldogs and local ratters in Paris, France during the mid-to-late 19th century. Geological age: Recent (Holocene). Environment: Urban domestic dwellings.

Uses & applications

Primarily used as a companion animal and for competitive exhibition. High value in the pet industry and for social media content creation.

Geological facts

Despite the name, the breed originated in England before migrating to France. They are known for 'bat ears' and their inability to swim or fly due to a dense, front-heavy body structure.

Field identification & locations

Identify by the flat face (brachycephalic), large upright ears, and stocky build. Commonly found on couches or in city parks. Field collectors should listen for distinctive snoring or 'gremlin' vocalizations.
