1. Never shoot a horse that is standing. Wait until the horse you want to shoot is lying down. It's probably a good idea not to kill a horse unless you have to, if it's sick. Horses are pretty smart, you know. And they really shouldn't be killed unless it would make them happy to be killed, if they're sick or something. It's kind of the humane way. It's kind of like assisted suicide. 2. Make the horse comfortable. Place a blanket over his face and stroke him until he is calm. 3. Wait until the horse is asleep or loses consciousness. 4. Load your gun. 5. Walk over to the horse very quietly. Do not wake him. 6. Press your gun gently into the space behind one of the ears. Point it down. 7. Step back as far as you can still keeping the gun in place. The horse may kick when you shoot. You could be injured. 8. Shoot once. 9. Jump back and away from the kicking legs. 10. Wait. The first shot should have killed the horse almost instantly. The kicking was just the horse's nervous system shutting itself off. 11. Walk slowly over to the horse. Check if it is breathing. If you shot properly the horse will not be breathing. 12. If it is necessary, place the gun in the same position as on the first shot and fire again. Wait longer. If this shot isn't successful you will have to shoot again. You can't leave the horse there to die in terrible pain. 13. Wait twenty four hours and then dispose of the horse's body.
