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 Paris cafés. The upright bat ears were later set in the breed standard in America. A Frenchie is compact and muscular, usually 16 to 28 pounds, with a square head, loose wrinkled skin and a short, smooth coat in brindle, fawn, cream or pied patterns.
Most are playful, affectionate and adaptable, and they tend to be quieter than many breeds. Their popularity hasn't made them easy dogs to keep healthy, though: the short muzzle brings breathing, heat, skin and spine concerns. Labels like "mini" or "teacup" aren't recognized varieties, and shelter dogs labeled French Bulldog may be mixes, so look at the dog in front of you rather than the label.
