I wouldn't stand by and watch any animal dog, cat or lion attack my animals which includes my dog.
Whether or not I would shoot it depends on the cituation and the animal.
It's hard to answer a question like this without being in the cituation. Especially when it has to do with neighbors.
Hunters on my property would be in my territory and I would have run them off long ago. Youi need permission to hunt on someones property and that includes allowing a hunting dog on private property.
If the dog disappears for a few weeks that might show the owner a big lesson.
Not everywhere. That's part of the problem discussing this. Dogs can't read "No Trespassing" signs. In some jurisdictions, like Arkansas and Oklahoma, dogs can go onto your property. That's legal unless they are threatening of damaging and you better have a good story. I don't believe the hunters can go onto your property to retrieve the dog without the owner's permission, not sure about that, but there have been enough stories making the news in Arkansas and across the border in Oklahoma about dogs being shot by an owner when they were on his land and him going to jail or paying huge fines that it is clearly not illegal for a dog to be on someone else's property. I spoke to a customer at the local
Tractor Supply who said he'd received $12,000 from a someone who shot his dog on their property. Blanket statements like yours and Bullitt's on it being legal everywhere to shoot an animal on your property are just not accurate, even if they are attacking your chickens. Each state and often different jurisdictions have their own laws.
You're right. You have to be I the situation to know what to do.
I'm not anti-gun at all. I own one and I use it when I deem it appropriate. I have shot dogs that were killing my chickens, dogs dumped in the country not neighbor's dogs, and drug them off to feed the coyotes, vultures, and maggots. I believe in matching the weapon with the prey, the owner's experience and skill level, and the circumstances. They are all important. I've used a shovel and an ax to dispatch certain animals too. A gun is not necessarily my first choice but sometimes it is the best choice, and yes, even when it might be against the law.
I've seen the damage a ricochet can do to a 12 year old boy's kneecap. I spent over 30 years in the New Orleans area. One of the New Year's Eve traditions is to go out on the levee and shoot your gun in the air. About 10 years ago one of those bullets fired in fun hit a woman in the shoulder. It missed the baby she was holding but messed her shoulder up pretty badly. I can't even envision shooting a rifle, even a .22 short, in an urban or suburban area even if I knew I wouldn't get caught. But that's just me and my sense of ethics and responsibility. Obviously not everyone feels that way.
