The Bulldog’s head is not as round as the Pug’s, and his ears are a little smaller than the Pug’s. The Bulldog is aggressive, very brave and looks more powerful and tough, while the Pug is gentle and gets along very well. Some Bulldogs have upright ears and are colored in tiger, camel, black, and cow, while the Pug is generally gray.
