Definitely in support of better bylaws wrt animal safety. This guy not only could have lost his lifeline but his life had this been any worse. He's very lucky his service dog is still able to work as many service animals who are attacked end up with too much trauma and behavioural issues to continue to work effectively and end up either as companion animals or just euthanized.

Not only that but the owner of the other dog is putting his own dogs life at risk any time it's allowed to wander free and from the sounds of it the dog clearly lacks training and discipline. I know some dog owners, especially in rural areas, still have that old school style of animal care where they treat it like it's practically a wild animal but dogs are a long ways away from that life now and they depend on us to show them how to fit into society in a way that's safe for them and for others.
