Seriously guys, the way I see it. If you know your dog and if you can understand other people, that act isn't a problem. I walked lately passed the garden with a very low fence, I had my "bad dog" on a lead and two rottweilers jumped out of the house, stand against that little fence and appear aggressive. The owner ran after his dogs calling them home. All would be fine if the fence was higher. But in that case I felt like me and my dog were in danger.

Dogs barks as they are made for protection. But no one would report you for  having  your barking dog behind locked doors. As same if you don't let your pet to chase the postman. 

I believe, that act, if it's happen, will put to jail irresponsible idiots and saves some dogs life, as many of those ppl will start being careful.

I am looking forward to banned owners (for life) act - little dream, and I would love to hear, that they dealing with dogs fights as well.

It really sounds like prevent, rather then getting rid of a "bad dog". 

But I may be wrong. We shall see in practice.

I love my dog enough, to make sure she is not aggressive and won't do any harm. We have deal with our postman, he is knocking to the window and leaving parcels on my stairs, either in neighbors house, letter box installed, dog out in a garden, but fence is solid. And we treat stranger's kids with no trust - means we walk across the road, just in case the little alien(means kid) starts, panicking, screaming and jumping. As I know my dog will read it as " common! play!".

I believe that all of us had little situation like this and you know exactly what I am talking about. Dogs owners knows better how to deal with things, and it's easier for us to understand and avoid it, then blame others for their fear. At the end of the day, their ours dogs and ours responsibility, as" your dog - your poop" ;)

Have a good day;)
