Z for Zachariah Chapter 3

Is the man part of the military? I would be very hungry if I had to live in a radiation suit. What happend to David's dog? A carbine is a good rifle. Why would the man waste bullets on a chicken, when he could go up and stomp on it? I hope the man didnt drink any of the bad water. I'd carry a gun in my hand at all times if I was the man.
