About halfway through the movie you will get to a scene with a bowling alley.There will be a lot of white bags all over the place. They contain people and animals. The entire scene the animals are crying loudly as if in pain and struggling0. A blonde man walks through the room, making a speech and kicks some of the bags, eliciting more pained cries. He stops mid-speech to stomp one of the animals, presumably a dog, to death. While you don't see the animal the shot is very close up on the bag and graphic, bloody and very traumatic.
This is the only time an animal is harmed.
