The French Bulldog, or as they’re more affectionately known “Frenchies,” are the most popular pup on Instagram, with 37,426,453 on the #FrenchBulldog hashtag. Unfortunately, vets in the UK aren’t falling for Frenchie fever, and point out that hairless French bulldogs are a result of extreme breeding that’s subjecting these dogs to a barrage of genetic abnormalities. Like pugs, Frenchies are short-faced (or brachycephalic) dogs, and this particular skeletal structure can lead to breathing problems, other skeletal issues, and “cherry eyes,” which is a phenomenon that leaves dogs with a large red mass in the corner of their eyes that can drastically increase the chance of infections.
