not on screen but it is implied there has been drinking in the investigation scene when spirit sniffs at a bottle lying next to one of the men that still has some alcohol in it
The female lead (horse) is injured after being shot at and swept over a waterfall. It is unclear whether she has a gunshot wound or was injured after losing her footing and falling into the river. There's no visible injury; she remains lying in her side, half out if the water and breathing hard. There is a lengthy scene in which the male lead (horse) stays with her through the night while she is clearly in pain. When he is forcibly led away, a man remarks "Leave her; she won't make it." The Native American man then comes to her, but it doesn't necessarily seem like he can help. Spirit clearly believes her to be dead until she is revealed to be fully recovered at the end of the movie.
The movie is about men trying to "break" Spirit, a wild stallion, so that he can be ridden. When he resists capture, he is extensively chased and then pulled to the ground with lassos around his neck and legs. When he bucks off all who try to ride him, he is tied to a post for three days without food or water. We see him growing tired and longing for water. When he is ridden again, the man vindictively uses his spurs throughout. When Spirit stops bucking, he looks down at his legs, which are shaking from exhaustion.
No mutilation is depicted. A horse bites at a man's hand, briefly pulling the finger of his gloves and perhaps pinching the skin. No injury is shown. In the next shot, the man's hand is bandaged, but the placement of the bandaging doesn't match the implied injury. When the man reaches between the horse and one of the stall's vertical posts, the horse leans to the side, crushing the man's fingers. Again, no injury is shown. Use your discretion.
The male lead (horse) is tied to a post for three days without food or water to weaken him so that he can be "broken". When a Native American is captured by the soldiers, he is also bound to a post with the intention to deprive him of food and water, but he soon escapes.
He doesn't die from it or sustain and permeant injuries, but there are numerous times throughout the movie where Spirit acts n a way where he puts himself at risk for others.
Getting captured to save his heart, almost getting shot to help Little Creek, jumping into a river to save Rain, almost getting crushed to death by a train and later burned alive of asphyxiated to save the Lakota horses - it's a theme throughout the movie.
An army soldier taunts a captured Native American, visually identifying his tribe and making insulting stereotyping remarks comparing the people of the different tribes. The man is visibly offended.
There is a moment in the narration when Spirit is jealous of the relationship between his love interest Rain and a human, where he refers to it as "unnatural" Kinda funny but not actual bestiality lol
No vehicles crash. A train engine that is being pulled uphill by a team of horses is released and does end up falling dramatically end-over-end back down the hill. It is not an active or occupied vehicle and no one appears to be injured.
No one drowns, nor is there significant threat of drowning. The female lead (horse) falls into a river and is swept downstream. The male lead (horse) tries to save her because she is unable to fight the current. They go underwater for about two seconds after being dumped into a deeper section of the river, but both otherwise keep their heads well above the water. After they go over a waterfall, the male lead looks frantically around, but spots her lying on the far bank.
Not bloody or gory but when the female lead horse gets shot, you can see the red bullet wound on her shoulder, it’s not graphic but it may mildly disturb sensitive viewers
