Several pet monkeys are seen. Later we see their empty cage and are told they have been killed. A helicopter crashes into an animal pen; a few goats are seen but it is unclear if any were harmed. A dog participates in a military raid; we do not see it injured and although we do not see it after the raid, its real-life counterpart (named Cairo) survived so we can assume the movie dog lived too. Zero Dark Thirty

All of the mammals in the movie are anthropomorphic and the movie is animated. Throughout much of the movie, the main characters are in peril, but are never seriously harmed, even though at one point it appears that the male protagonist (a fox) has killed the female one (a bunny), but it turns out to be staged in order to trick the villain. Both of the protagonists suffered from bullying in their childhoods, which is seen on-screen. The bunny character gets a small slash across her face from a fox's claws (not the male protagonist). The fox character is forced to wear a muzzle. A plot point is that a serum turns some of the animals into aggressive, feral beasts that attack other animals. This is sometimes seen, but the attacks are never fatal. One character (a panther) suffers scratches around his eye during such an attack (he may be blinded on the eye). A children's stage play includes lots of ketchup as fake blood in a death scene (we know this is fake from the beginning). Zootopia
