I agree that he could have phrased his question better. "Is SHE friendly?" would have been much nicer.
And what was he doing in a park with so many dogs anyway, if he is afraid??

I have trouble with kids on the street. As soon as they see our door open, they come running, screaming the name of whichever dog I have out. It's ok, but not when I'm trying to get Riley to go potty
When we moved in, we told these kids that Kito is not fond of kids. It's not really that, but he doesn't like when they come running at him screaming. He has to be calm, and so do they, and they have to let him smell them, and then pet underneath his chin--that's just the way he is. Abbey and Riley are over-friendly, so they're not a problem, but we still have to keep them sitting when the kids come over.
