19. Boston Terrier
Nicknamed “The American Gentleman” do to their tuxedo-like markings, these dogs were originally bred as fighting dogs… But don’t write them off just yet!
A Boston Terrier is a lover, not a fighter. These dogs are highly intelligent and are full of energy, despite their small, stocky size. They are affectionate and loving, if a little cheeky. Their size, energy, and sturdy build make them great family pets.
