I just wanted to say, humans can do the same thing. It's a psychological thing to fall over when we get shot. Which is why drugs can affect such; its not that animals have a better adrenaline system. (I'm pretty sure.) As with anything unless youre taking out a major portion of the CNS (central nervous system) the human or animal will be able to act until enough blood flow or oxygen is depleted from the brain. Even with a major wound that can take up to a minute.
