carry a blade, that's a good start.
i believe local leash laws would affect the legalities of the situation.
i also believe local town discharge laws would also affect the legalities of the situation.
warning shots are a no no in MA...stick with that.
not sure i could pick out the correct dog in a vicious dog fight with my CCW, alot of movement going on there, might kill my dog on accident.
i find the cited law interesting....seems like it's okay to shoot the dog if the owner isn't around to attempt to control it...but if he/she is around, then you can't cuz they are the ones responsible for their dog and (i guess) they deserve the chance to stop the attack and control their dog. i may be interpreting that wrong, however.
i had a pit for a long time, awesome dog. just didn't like cats...AT ALL!!!
i remember a story that happened about 8 years ago in Somerset, MA (where there is a mandatory leash law). a man, his wife, and their dog walking on a side street come up to a house where a man is working in his open garage with his rotweiler hanging out with him. rotweiler spots the couple and their dog, starts charging & barking at the walking couple. once the dog was off of the owners private property and on to the public roadway, the guy pulls out is .40 CCW, pops off 2 shots, hits the dog with one right in the eye and out the side of it's face. the dog stops in it's tracks and starts rolling around on the ground, howling, then eventually heads back towards the owner. the owner starts freaking and calls the cops. the walking couple stays and gives their statement to police, and then walks home. no charges, no license suspension, no NOTHING!!! the dog survives after a visit to the vet and a major vet bill. there was only a bogus law suit from the dog's owner for the vet bill to be paid by the couple, which he did not win and ended up having to pay himself. he didn't have his dog on a leash, he didn't have his dog under control (allowing it to leave his property), and witnesses confirmed the dog was charging and displaying aggressive behavior. case closed.
i'm trying to find an article about it, but can't at the moment. it was in "the spectator" which is a small local newspaper in the area. i remember this story clearly because it happened just before i started to become interested in firearms and started the quest to getting my LTC.
as with all firearm-related incidents, i feel it's extremely circumstancial.
