Perhaps I have been lucky but I've obviously missed them - or sit in a different area of the Gardens.
I did say that part of my post was tongue-in-cheek but while I deplore aggressive dogs and feel dreadfully sorry for the child who was attacked, I do also believe that the majority of dog-owners are responsible and don't want aggressive dogs so I'd have to disagree with a proposal to ban all dogs. And no, I'm not a dog owner.
You haven't been attacked or threatened by any dog in the Horniman. You've just seen some which made you stressed. I wasn't comparing the equivalent dangers, I was merely pointing out that what stresses/irritates one person may not bother another.
