We made a report. I ordered a Cold Steel ash walking stick AND bear spray. I also talked to a policeman over the phone who was far too friendly when speaking of the dog's ownder. The dog was on a leash, but pulled free of the ownder when attacking. The guy was too old for the giant dog, and it was not adequately trained.
It seems that you can do anything that you need to when defending yourself here from dogs.
But - It is not legal to carry concealed around here.
We may want to see a lawyer about this event...not sure about this.
Here in Georgia, the police arrest dogs. REALLY! They call animal control and they lock the bad dog up. The owner gets to pay a $300 fine for a first and minor offense.
Second offence and the owner can get a much larger fine and the dog gets a chance to reincarnate as something better and less violent.
If the owner actually "sics" the dog on someone, he can go to jail. This offence is handled differently because the dog was acting as the agent for the owner.
Arty, you are in a difficult place. Your wife has a justafiable fear. Yet if you carry a gun, you can go to jail. I would have a talk with the owner, certainly about your medical expenses. There is no question but that he is liable.
If he refuses, there is no question about filing a lawsuit. Do it. I think that you deserve compensation for not only the expenses, but also pain and suffering as well as punitive damages against the owner.
I'd take a strong stand here. Your wife has been injured by a huge dog. Now she probably has a fear of even walking your dog. If this dog has attacked other people (there should be a police record) you will likely have a slam-dunk win.
I hate to reccomend the genre, but you could get a personal injury lawyer. The first visit is free.
