dog metaphors are all about devotion, devotion to a person, a concept, a place etc, to be a dog is to be devoted.
there are three types of dogs
dog 1: pet dogs; loyal and devout, they follow after the object of their devotion desperately even when it is not reciprocated or out of their reach. they are usually (but not always), somewhat innocent (think puppy love). they are below or believe themselves to be below the devoted in terms of power/worth/status etc, at the end of the day they are just someone's dog. they feel they are owned by who or what they are devoted to, whether enforced by them or by their "owner" differs. some are naturally selfless and obsessive, others bullied into submission, some are mix of both.
dog 2: guard dogs; aggressive and loyal, protector and/or provider in some way, (think knight and king dynamic) use anger and violence as an expression of love and devotion, either prone to harming who/what they are devoted to or are dedicated to the protection of it in all forms. this varies depending on the morality of the characters. low morality guard dogs are possessive and challenge their devotion using violence and threat to gain control. others are valiant and heroic, usually with a strong moral code that will not be broken. they are often bad at communication and addressing their own emotions, choosing to speak through their actions rather than using words.
dog 3: wild or wolf-like dogs, at their core they are a large animals that are unaware of their strength and size, their displays of love and affection, although genuine and passionate, can end up harming or negatively impacting the objects of their devotion, (think dogs showing affection through biting not realising the sharpness of their teeth), usually impulsive, controlled by emotions and erratic, they are volatile and often illogical. to love and be loved by them is dangerous. violence is a natural or taught characteristic of theirs that is inherent and inescapable. these characters often don’t intend to cause harm and when they do it’s usually from an un-calculated place of impulsive destruction or an emotional outburst.
