If assault by dog was treated as assault by owner (since in no way can we really blame the dog) then I think we'd see a rejuvenated will to take proper responsibility for your dog.
Why can we not blame the dog? I spend every evening at the dog park, and attacks there aren't exactly rare. Usually it's a little territory dispute, or a dominance display. Totally minor incidents, but they do happen. And it's the nature of the dog that causes it, nothing to do with the owner.
When some un-neutered male, or female in heat is brought to the park by a completely moronic owner - they we tend to blame the owner. If the dog is showing aggression, and that is reinforced or ignored by the owner, we blame them both.
But some dogs just have it 'in them'. My favourite dog, besides my own, is a pure bred Irish Wolfhound. She is such a pookie. But she plays hard, and many dogs can't handle it. It's in her nature to attack and kill, but she doesn't - she aggressively plays with other dogs not in her weight class. It's what her breed does. She is fast, the fastest wolfhound in North America. So no dog there can outrun her, even when she isn't trying. It's in her nature to pin other dogs to the ground.
She does it to any strange dog, and there is nothing they can do to stop it. Nothing a human can do either. So, she has to be leashed when new dogs are around, or she will 'starfish' them to the ground. It's the way she is.
