If Uly has one fault, he is apt to bark at strangers. I'm pretty sure this is either territorial or caused by anxiousness, or a bit of both. I'm rather hoping he will grow out of this trait. In the meantime, I try not to make a big deal about it – I don't want him getting a lot of attention from me when he barks.
My response at the moment is to either tell him 'No noise', gently 'Shush-h-h', ignore him, or walk him away from whoever he's barking at. I haven't really worked out which is best and I think it rather depends on the situation.
Of course, some people want their dog to bark at strangers, and I don't mind him giving one or two barks when someone comes to the door, but I obviously don't want it getting out of hand. More of this later, I think.
