I think that dog owners SHOULD be held responsible for anything and everything their dog does. They train the dogs, they teach them obidience and patience. So why not when one flips out should they not be held responsible?
Young children die from Dog attacks often all over the world. People should be weary of their dogs and make every effort to keep an agitated, sick, or dangerous dog away from people. ESPECIALLY while walking it, that is when the majority of children will ask the person if they can pet the dog. I know its hard to say no to a child asking to pet the cute puppy, but if the owner is certain the dog is sick, aggitated or vicious, they should cross the road and keep it away.
People have nervous breakdowns all the time, dogs do too, especially trained guard dogs, they wig out the most. RCMP have to keep putting their dogs thru constant re-training to keep them in top shape and even in some cases have had the dogs councelled. I have no idea how you would councel a dog, but hey whatever, our tax dollars hard at work
If my dog attacked someone, I would take full responsibility for it, just like if I was in my car and I hit someone, I would be held resposible for that. Its essentially the same thing. You are in the car, you should be in control. You are walking your dog, you should have full control over your dog at all times.
If your dog escapes from your yard and attacks someone, well then that is the owners fault for not having the dog properly leashed, no proper fencing, no fence locks, whatever it may be. As well if a child goes into the yard and is attacked by the dog, there should be warning signs, as they will keep the majority of kids out of your yard.
So in short, if you hit someone with your car, its your fault, if your dog kills, or attacks someone, sure you should be punished and your dog should be put down. I dont know how far the punishment on the dogs owner should go, but I believe Canine (<- haha) manslaughter would be the most I would go for. (They have vehicular manslaughter why not Canine manslaughter).
I dont agree with the woman in your post getting second degree murder charges against her, possibly criminal negligance or as I fore-mentioned canine manslaughter (lol makes me laugh every time). Second degree seems way too harsh. Oh yeah tack on a $2000 fine as well.
There's my 2 cents (and a few nickles too)
