If you hit one too high in the shoulder, it will will strike the animal inthe vertebrae, which puts the animal in a temporary shock. Then it will recover and be gone with little sign of any kind of hit. If you look at a deer skeleon you will notice wher ethe shoulders are the back bone dips down, however the vertebrae are longer there ans stick up even with the rest of the backbone. If hit it will just shock the spinal cord temporarily dropping the animal.
