A section of the book is dedicated to White Fang thrown into dogfighting and all animals are prone to being struck with clubs to force them to comply or stop fighting back.
A child who threatens to beat white fang is bitten on the hand badly by him, and many children who threaten his owner's child are attacked and driven off by him, but do not die.
A revolver is wrenched between a dog's closed jaws sideways to try and pry them open while another man insists "don't damage his teeth." Very minor and only reference
Technically no but the word used to describe Beauty Smith is so similar sounding I don't fully trust it, and it's footnoted in the dictionary as same enough, so I'm saying yes. [N---ardly]
A character takes a gun, leaves the area, and the then-protagonist hears a gun fire three times but doesn't see the result. A gunshot misses a wolf and hits a tree. Offhand mention of hunting moose or cariboo with rifles. A revolver is used to wrench open a dog's mouth, or otherwise threaten, but not shot or described on the page.
Uncertain but some detail goes into describing the gaunt/starved bodies of the dogs and their bones, and later in Beauty Smith's "ironically ugly" appearance.
White Fang's father One-Eye inexplicably disappears when he is a cub and he is never taught why, because wolves can't talk. But his mother does, the narrator explains.
Grey Beaver, White Fang's owner, is steadily driven to bankruptcy and alcoholism by the white man Beauty Smith as a means of buying his dog. The last WF sees of him he is penniless as a result of his addiction.
White Fang is held against his will by his first owner, Grey Beaver, because his mother wishes to stay with humans while he wishes to go. When his mother leaves, it is the only life he knows and can stay in anymore. Later sold off unwillingly to a cruel dogfighting enthusiast.
Emphasized that White Fang does not think like men do, and would not feel bad or hurt by knowledge or memory of things, only react, but all he endures can be likened to repetitive trauma and resulting stress response to survive.
The opening prologue features a man studying his hands and the muscles in it and that the wolves wish to rip open and devour it, and his body. White Fang repeatedly bites and slashes open human hands, and is punished for it.
The word squaw is used by the narrator to describe native american women repeatedly. "Savage" repeatedly used to describe White Fang's masters who are Native American and beat him to instil fear. See N-word entry.
