I like it, too. Mateo is neither shy, nor fearful, but still strangers will reach out to pet him-constantly- without asking first. It's the rudeness that bothers me most.
Oh, and when he's occupied with a smell- on a tree, or his head is in a bush- people will ask if they can pet him-- and then reach out to pet him from behind, which startles him a bit. I have had to make a point of saying, yes...but wait until he can see you, first!
Another good excuse is, "Now is not a good time," and continue walking. I have used that a lot here in the city, when people are asking to take his picture, especially. Or when I just don't want to be bothered...
