Pugs, Frenchies, boxers, shih-tzus and other flat-faced dog breeds have been trending for at least the last decade, thanks to higher visibility (usually in a celebrity's handbag), an increase in city living (smaller dogs for smaller homes), and possibly even the fine acting of Frank the Pug in 1997's Men in Black. We're not ruling it out. These small, specialty pure breeds are seen as the pinnacle of cuteness – they have friendly personalities, endearing odd looks, and are perfect for Stranger Things video montages.
