There's a lot on the web about the affect of shock on people. It's not much different in animals.
This is a list of common symptoms. Of course most of these can't be detected in a wounded elk but some can. If you've shot many animals, you will likely recognize some of them.
Some of the typical signs and symptoms of shock usually include at least two or more of the following:
Confusion or lack of alertness
Loss of consciousness
A sudden and ongoing rapid heartbeat
Sweating
Pale skin
A weak pulse
Rapid breathing
Decreased or no urine output
Cool hands and feet
Any of these alone is unlikely to be a sign or symptom of shock.
