There is some truth in that, but at least no one here is saying "Banning's not the answer. In order to protect yourself against someone with a dangerous dog all you need is to get a dangerous dog yourself."
Ah ok. Good! I have three small dogs and yes they can sometimes run into the garden yapping their heads off, especially if they see a cat walking along one of the walls. Not all time though (and yes I do call them in). Most of the time in the garden they're quiet.
If any of my neighbours didn't...
