Horses are used and killed in battle. A dog is seen very skinny with visible ribs, although this is presumably because food was unavailable rather than withheld.
It is a movie showing the horrors of war. There are people with legs blown off, faces blown off, blown in half, suicide with a fork. It is extreme gore realistic to what it was like.
A soldier is shot through the eye and the bloody wound is briefly shown. Another dead soldier is shown with a bloody eye (subconjunctival hemorrhage). During the final battle a soldier is repeatedly beaten in the face with a helmet and you can see his eye is damaged from it.
Many of the soldiers are teenagers, and a letter from home reveals that a character's child died prior to the events of the film, but no children die on screen.
Not exactly, but at the end of the film a character tries to save someone and gets into a struggle with the attacker which ends with the character getting stabbed
When the soldiers are positioned at the wall of the trench about halfway through the film, one turns around and retches. You hear it for about 5 seconds, but it’s so foggy that you don’t see much. No other vomit aside from this.

When Paul finds Tjaden on a stretcher in the city square, Tjaden says “I’m not going to let them amputate me; I’m not going to live in the world as a cripple.” Eventually, he kills himself to avoid having mobility impairments.
No, but during the final battle a soldier is held face down in a puddle of mud and nearly drowned. They linger on him gasping and the mud bubbling for a while.
