Shooting The Horse? Real or Fake?

[deleted]

Horses used in movies are all trained to play dead.

It's unlikely you will see this but https://equinehelper.com/bombproof-and-desensitize-a-horse-ultimate-guide/

Also I don't recall if the gun flashed but the sound could have bee added later

When he shot the horse, it looked like he was pointing the gun slightly off to the side, not directly at its head. But if that was a fake horse death (and I hope it was), that horse should have got the Oscar for best horse performance. He (she?) was also lying there playing (?) dead for a long time, and I couldn't spot any breathing movement.
