French Bulldog vs Pug: Size & Growth Compared
Updated October 2026
French Bulldogs are the stockier, heavier breed — typically 16–28 lb vs 13–18 lb for Pugs. The Frenchie’s bat ears and muscular, compact frame make the difference obvious side by side, though both are small, flat-faced companion dogs with the same roughly 11-month maturity timeline. Both breeds gain weight easily and need strict portion control.
