Dogs

Dogs are a reoccurring theme in the Deep Leffen Alternative Universe. Between being mistreated, cast with unfortunate characteristics, and often referred to with lesser regard, dogs are often associated with misfortune and low status.

Characters
Deep Leffen has a dog named "Marcy" who possesses the following traits
 * Dumb
 * Racist
 * Mains little mac
 * Is unable to be neutered
 * Is an NSA informant

Deep Leffen reveals that Marcy has Trout's disease does not have a lot of time left to live (estimated 2.36 to 6.6 days, translated from Leff years)

Hungrybox has a dog named "Braxton Leatherbarrow", who came from a liter of six puppies. It is implied that Hungrybox is about to sacrifice Braxton based on the fact that Braxton "has a few days left to live" and made "sacrifices of the pups to Moloch one night at a time".

Play Style and Mechanics
In the Deep Leffen Alternative Universe, dogs are known to be representative of both smash characters and smash players, typically having a lame play-style and low skill ceiling. Despite DeepLeffen's wishlist for a polite yet self-harming dog character, Sakurai designates the dog character as impossible to use, yet one which "advance[s] the meta by a few years.

Fire and Hell
Dogs are almost commonly associated with heat, hell, and burning in the lore. Hungrybox tells a kid his dog is going to hell for various reasons, including "not loving [the child] enough to stay alive", "[the child] maining Luigi","[the child] not being able to tech for the life of [them]",not being able to beat the dog in smash, and having "zero fundamentals" . Sakurai famously burns a dog, mistaking it for a small, talent-less child with little aptitude for smash that had the face and body of a dog . Hungrybox and Deep Leffen often consume hot dogs, even referring to them as "dogs" at some points.

Hurtboxes
In one of the only few photos tweeted by Deep Leffen, dogs and dog-like creatures are frequently seen.

Other mentions
Deep Leffen mentions that he will not be convinced that a guy who "has sex with a trash dog" isn't a psychopath or degenerate.
