A bat that attacks the protagonist gets killed by her when she hits it with a chair. It may not have been a real bat though due to the movie's occult themes including witches and black magic. Several maggots cover the floor and when the room is entered some appear to be stepped on. The maggots are real and most likely have been stepped on for real. In one scene, a dog is accused of having bitten a boy, and is threatened to be killed if its owner doesn't leave the house. He does so and the dog is fine. However, later on the dog is possessed by an evil force and kills its owner, leaving its fate unknown. There is no implication of its death. Suspiria
