French Bulldogs trace back to small English Bulldogs that lace workers carried to France in the 1800s, where they were crossed with local dogs and became Parisian café favorites. The upright bat ears were later fixed in the United States. A Frenchie is compact and muscular, usually 16 to 28 pounds, with a square head, a very short muzzle, loose wrinkled skin and a short, smooth coat.
Many are playful, affectionate and fairly quiet, which suits shared walls in apartments and lofts. Popularity has made them the most registered breed in the country, but the flat face brings breathing, heat, skin and spine problems. Terms like "mini" or "micro" aren't recognized varieties, and a shelter dog labeled French Bulldog may be a mix, so look at the dog in front of you and budget for vet care.
