I live next to a green area where many dog walkers are. Occasionally when I'm in my garage the odd dog bounds in uninvited, usually a spanial type or labby, or a jack Russel ish type. They are always friendly. They are in and out in seconds usually, tails wagging, sniffing, the things dogs do.
Always followed by an apologetic owner shouting them.
I don't mind it if I'm honest, if its a friendly dog, then it's quite a nice thing.
But these killer ones are a worry.
How am I supposed to know if its a wrong un?
