Different states and counties are going to have different laws concerning wildlife and dogs. Like comparing oranges and apples and it can't be rationally discussed here. Mentality and the way different hunters were "brought up" are additionl factors.
One thing about it the (and I use the word hunter loosely here) hunters that have the lease that shot the neighbors dogs probably will lose their lease over this and they should. Even if it is timber company land, they do not like controversy and problems with their neighbors over hunting. Most will pull leases and offer them to local people or just close the hunting on the lands they own.
