If I see someone with a SD, I smile and usually make a comment to the handler (usually along the lines of "Beautiful dog,") but nothing to distract or potentially distract the dog. And I only comment if the handler looks at me, or is already talking to me. (At work, for example). Otherwise, I admire from afar.
I saw a picture of a malinois that appeared to be a MWD wearing a vest with a profane word thrown on there, but for some reason, it seems like that'd be more effective....
Why can't people just ask? Ugh.
