I wouldn't bother with inspecting the foot. I also would not shoot her with a dart gun. She gets too shaken up to begin with, I would give shot a wait and see.
Take your time. Don't think she has to be in a chute to give a shot. Use the other cows to crowd her either in the lead up to chute or put them all in a trailer or small pen to the point she can't hardly move and give her the shot.
If your going to keep her after she gets over the foot. Get her in the habit of going through the squeeze. Open it up as wide as it will go, send her with cows in front and back of her with feed outside of the chute. Don't get in a hurry. B
