the situation is too vague
Is it your property, public, someone elses? And who does the dog belong to? why are you contemplating shooting a dog in the first place, unless he attacks you on public property or you are on his turf, you will go to jail, as a "dog" is considered a "loved one" in some states, in most actually. On top of prosecution you will also likely get sued, or worse.I have a Lab and a 190 lb Rotti, thaey are both gentle as a lamb. I owned a Gym and the biggest guys would jump over the counter if they saw a rott or a pit, and that was with one of my little guys, dogs bark for many reasons, hardlly ever bark if they are going to bite, I never had a dog of mine bite anyone, and I have 4grandkids that are just now turning 3-6, my big old rot never even knocked one over. Either you are misunderstanding the dog or vice versa. Down here the only time you ever hear about a dog getting shot, is by a dumb rookie who is afraid of dogs. Old timers just walk right by them, if a dog attacks you for no reason, then you have to defend yourself, but you better be right. My uncle used to ride his bike and get chased by this big coon dog, one day he got fed up and took a rubber hammer with him on his daily ride, that dog never bothered him again, just used to watch him ride by.
