French Bulldogs trace back to small Bulldogs that English lace workers took to France in the 1800s, where they were crossed with local dogs and became fixtures of Parisian cafés. Americans later set the upright bat ears. A Frenchie is compact and muscular, usually 16 to 28 pounds, with a big square head, a short muzzle, loose wrinkled skin and a smooth coat in brindle, fawn, cream or white patterns.
Many are playful, affectionate and adaptable, and they're quieter than most small breeds. Popularity has made them the most registered breed in the country, and the flat face brings breathing, heat, skin and spine problems. Terms like "mini" or "teacup" aren't recognized varieties, and a dog listed as a Frenchie may be a mix. Plan for climate control and vet bills.
