Out and about with Roxy, we have discovered that the most annoying thing for us is an excitable dog, one that is not on a lead ("Oh, he's ever so well behaved, and really friendly!").
Far too many people don't realise that while their dog may* well be a friendly dog, to have it dash up to you, a young child, or a nervous dog under your control can be a fraught situation.
Fortunately, while Roxy is a little naive about the outside world (after three years in a rescue centre, she's bound to be out of touch), she is also generally very friendly and very placid. However, since idiots abound, we are obliged to walk her in public with a muzzle.
Taking our new friend out for her evening walk one day, the three of us encountered wave after wave of hyperactive, noisy dogs, none of which could have been larger than a bowling ball. All of which apparently oscillated between 'happy-yappy' and 'Come on! I'll f***in' have ye!' with not a lot of changeover time.
Understandably, Roxy was more than a little unsettled by it all and tended to cling to us more than the most insecure of shower curtains. Most of the time. Finally driven to snapping point (literally), Roxy lunged for a very noisy toupee, only to be brought short by us; we'd been ready for this.
I was about to say something fairly regrettable, when Julie, having sensed my mood as well as Roxy's, beat me to it.
