You see many dogs in cages that are barking. After we see the dogs get fed a piece of meat, two dogs wrestle, growl and pull at same meat aggressively, which is a bit jarring.
Dogs are starved, clearly dirty, chained, and kept in small cages in a dark basement. Made to fight over small bits of meat (human?) No idea how anyone could vote no.
There's two extended scenes directly of it (in both cases, eventually it is stopped), and one scene where you briefly see a video of a girl being sexually assualted (a guy is masturbating to it).
Lots of heads getting bludgeoned in this movie, and someone’s head is pulled apart from the mouth. Not exactly squashed but similar enough that it could be pretty upsetting.
Essentially, when the main character tells the nurse to close her eyes and cover her ears, you should do that too if you don't want to see the mutilation.
There is a scene showing the aftermath after someone forced themselves to vomit a tracking capsule (the act is not shown, but as someone sensitive to this I still found it gross).
I hope this fits here but there is a very explicit scene with a toilet full of s*it and someone searching through it for something. It's after the pharmacy scene.
