There's a dog in "Mold" that is seen barking outside the house. Since everything gets turned into mold, technically it's implied the dog did as well but it isn't shown or heard.

In reference to "Long Hair in the Attic", the character dies from a heart attack and is found dead. Just before he dies, another character mentions that he is sick from heart problems. It is not a seizure.
Soichi, the kid with the nails in his teeth, frequently has scenes where his teeth are mishap and seem to be missing. In "Layers of Terror", it is shown that Reimi's sister has multiple rows of (intact) teeth.
Several episodes, including "Hanging Balloon", "The Strange Hikizuri Siblings" (they were dead before the episode though, but it's the main focus), and "The Story of the Mysterious Tunnel."
During the seance, just after the candles go out, from 12:31-12:56 is the actual expelling from the mouth. Afterwards the ectoplasm is visible on the floor. The character has saliva dripped down their chin until the father takes over the characters body. Audibly it is not gagging but more of a slimy squish sound. I consider my emetophobia to be quite severe and this scene was a 2/10 for triggering. 1 being spitting blood and 10 being, you know if you’re reading this. I was able to play it back to get this info for you guys if that helps. 14:31-14:40 you can see the ectoplasm on the floor again after the kids are explaining to Shigoro that he was possessed by their fathers spirit. Misako begins crying and picks up the ectoplasm at 14:56-15:01 and runs away with it. 15:32-15:39 it shows a bit of the ectoplasm picked up by the brother in a napkin. 16:07-16:11 Misako has the ectoplasm sitting on her bed. They later say that is wheat flour not ectoplasm. 18:40-18:53 Misako is holding the moldy dried out pile of ectoplasm. 19:56-20:18 the younger brother has, what appears to be, a spirit come out of his mouth. Nothing wet and no gagging noises. Takes the form of a persons head floating in the air and follows them out of the house. Absorbs into the fathers headstone. Hope this helps
Yes. In Tomb Town, a car hits a person who subsequently dies. In Layers of Fear, a car nearly hits a semi-truck and then crashes into the woods. Graphic injuries are depicted in Layers of Fear.
