again, though, in a LOT of places anything other than a kill shot is going to get you an animal cruelty charge. My husband worked in law enforcement in 2 different states. Each one, it was legal to kill a dog that attacked livestock but shooting to wound was a huge fine. Now, if you shot to kill but only wounded, then you were ok. But if you were shooting with birdshot? Then it is obvious that you didn't intend to kill the dog and that is a felony here in AR. Personally, I'd prefer that the idiots keep the dogs at home but since they aren't responsible enough for that no WAY am I going to be charged with a serious crime. The same goes for paintball guns, BB guns, and other similar methods. If it can hurt the dog and cause a chance of pain or injury, then the cops have the option of charging the person shooting the dog. The livestock laws don't include a "less than lethal" option.
Rubber bullets are for humans. Where a less-than-lethal option is preferred. Usually they are used to subdue suspects. Now, if the cops are sent to arrest a violent person? They aren't bringing the bean bags.
Think of it this way. Someone is attacking you and you shoot them. If you only shoot to wound, you will most likely be charged. Why? Because if you are in fear of your life and claiming self-defense, then why would you only want to scare them off? The same basic principle is at work here. If your animals and livelihood are being threatened, then the goal is to eliminate the threat.
