Some class features (such as Monk's Patient Defense) or situations (such as being mounted) can allow for a character to take a Dodge action without using his actual action for the turn. That way, a Monk could use a bonus action so that all attacks against him have disadvantage until his next turn, and attack anyway. Or a mounted Halfling Fighter could command Fido to dodge for him and still multi-attack as normal.
