Dog owners:
"Aw, isn't he friendly?" is not an acceptable verbal exchange when your uncontrollable mutt jumps all over me in the street covering my work trousers in mud, crap and fuck knows what else.
Likewise, when your overly aggressive Alsatian starts growling and barking at me, "It's OK, he won't bite" is not much help. How do I know he won't bite? I bet every person who's ever been maimed by a psychotic canine was told "It's OK, he won't bite."
Keep the hound under control!
Edit: I love dogs - this was aimed at some of my moronic neighbours who can't keep their dogs under control!
