There are countless videos that show animals fighing until taken down. Once the predator starts to feed its as if they simply give up and cease fighting
Sure, to quote, from your link:
"They go into shock. Shock is a last-ditch effort by the animals’s body to preserve vital organs by reducing blood flow and energy consumption. The high adrenalin levels and endorphins associated with shock can act as pain killers. This is true of humans as well – a human traumatically injured in an accident may not feel pain until the shock wears off later. So, the animal isn’t calm at all. It’s mentally stunned due to its state of shock."
See that?
It's a last-ditch effort. Therefore,
in answer to the OP, yes, deer do feel pain, as does any mammal. Step on your dog's paw and see how it reacts. Pretty self-explanatory if you think about it...
Did you ever go into shock?
I have.
It can take minutes to happen after the traumatic event has occurred.
And...that doesn't mean the endorphins mask ALL of the pain.
Take an 8# sledge and whack your hand with it.
Then consider getting hit with 200 ft-lbs of force from a broadhead that misses your vitals.
See where I'm going with this?
Watch this video (last 30 secs or so) and listen what the shooting victim says about shock and pain.
The victim is
ALREADY whacked out on smack, the strongest painkiller available next to fentanyl, prior to getting shot. Think about it.
