I shot and killed a dog once. It attacked me the month before, and even though I talked to the owner about locking the dog up, I didn't trust him and I started carrying my .45 when passing by the owner's house. About a month later, the dog went for me again, so I shot him in the head. The owner was pissed. He jumped in his truck and found me, and shouted some obscenities but didn't actually threaten me.
