Labrador retrievers take hold and hang on tight as the nation's most popular purebred for 23 years in the row, and they seem to not be losing their luster. But no breed has rocketed up the rankings quite like the French bulldog, now the nation's 11th most popular purebred after its numbers more than quadrupled in the last 10 years. The Frenchie was 14th last year - and 58th in 2002.
