I forget where it was (somewhere near Tadsworth, iirc), but out in the country the other week, we were taking a walk and some huge dog starts having a go outside its owner's house. Not a yappy little thing, but full-on agitated wookie, which was troubling enough that I armed myself with a suitable chunk of rock to brain it. The owner comes out and we asked her – perfectly politely – if she'd mind taking her dog in for a moment. Which seemed not unreasonable.
Her response, delivered in perfectly posh Surrey, was 'no, he's not going to hurt you.' So she should there while the dog barked and snarled at us. I should have bashed them both on the head.
I don't dislike dogs, but I got a nasty bite as a child, and thus I really dislike being charged or barked at by them. I don't fucking care if he's being friendly or not going to bite me.
