French Bulldogs started in the nineteenth century, when small English Bulldogs traveled to France with lace workers and were crossed with local dogs. Americans later fixed the upright bat ears. Adults usually weigh 16 to 28 pounds, with a big square head, a short muzzle, loose skin and a smooth coat in brindle, fawn, cream or white patterns.
Many Frenchies are playful, affectionate and adaptable, and they tend to bark less than many breeds. The flat face comes with trade-offs, though: breathing trouble, overheating, skin-fold infections and back problems are common. Labels like "mini" or "teacup" are marketing, not real varieties, and a shelter dog called a Frenchie may be a mix. Each dog's needs differ, so plan for care and costs that could run higher.
