I like dogs, but growing up on a farm I have had to put more then my fair share down for a long list of reasons. One of the things that really griped my back side was when the “city” people would get tired of their dog or it would start to get “mean” and they would dump it. It is truly amazing how fast a domesticated dog will revert back to its hard wired behavior and start to hunt in packs and start to bring down livestock.
The local sheriffs department would do nothing about it but make out a report and tell you tuff luck.

When I got new neighbors who had a pit-bull I was less then thrilled. When they would let the dog out it would come over to my yard and stand on my porch and bark at us in the house. After making several complaints to John Q Law and being told that they could do nothing unless the dog bit one of us, I spoke with the neighbor. After a few weeks of not seeing the dog I figured that they had got rid of it, but Ohhh no they just stopped letting it out to heed Mother Nature’s call. All last winter I did not see the dog and then this spring their it was, back in my yard crapping and on my porch barking. So I talked to them again and was told it was a good dog, that it was real friendly and would “never bite” to cut this short when the dog had my kids on top of their swing set growling and jumping up trying to bite them I shot the dog.

I don’t think they were happy when I did it due to the fact they were out side standing there, and when I pulled it over to their yard so they could dispose of it I was called a long list of obstinacies and a murder (which made me laugh) So now to the moral of the story, I don’t want to have to kill some dog, but when it comes to the value of a human life, my kids, mine or any one else the dog will lose.

As for subduing the dog not a chance unless you think lead is a for of subduing .
That’s why animal control officers use long catch poles, so they don’t have to get that close, and most of the time there is an officer ready to shoot the dog if it gets to “out of control”
