This is an old thread that is largely resolved, but I'll add my two cents anyway:
All the OP did was revisit the location the attack, armed. Legal. The dog aggressively charged again. Not wanting a repeat of his first experience--shot it. Legal. He didn't go and murder the dog.
This
is an old thread . . . I have since made amends with the owner of the dog I shot. It was better than a year later when I was on my way home one Saturday afternoon and I saw a pickup truck, that I thought I recognized, apparently broken down on the side of the highway. I was off duty and in my own pickup but I pulled in behind to see what the trouble was.
I had my handheld radio with me so I radioed in, "Unit 4 to S.O."
"Unit 4 go ahead."
"S.O., I'm in my POV and going to be out with a stranded motorist on the highway at Ball Hill. White Dodge pickup with LPN XXX-XXX."
"10-4 Unit 4. Let me know if you need further assistance."
When I walked up I immediately recognized the fellow, and he recognized me as well.
"Hey, you're the guy that shot my dog!"
"Yes sir, and your the owner of the dog I shot after it attacked me, twice." I replied
"Well, I guess I had that coming," he said.
"So, what seems to be the malfunction here?"
Turns out the water pump was out. I had my tool box in my truck so I offered to help him pull it off right there and take him back to the auto parts store in town and get another one and come back and install the new one. About an hour and a half later we were done, his truck was up and running, and we had a good time getting to know each other while we worked.
When we finished up he thanked me and stuck out his hand and said, "sorry about the whole dog thing."
I took the offered hand and replied, "Sorry I had to shoot it, but sometimes you gotta do what you gotta do."
I've seen him a few times since and I think we're all good now.
